Definitions

  • the invention relates to a device for developing a control program for a knitting or knitting machine for producing a stitch product with a thread course transverse to the direction of production, according to the preamble of claim 1.
  • the knitting or knitting machines in question can be flat knitting machines, in particular with two needle beds, flat knitting machines or also circular knitting machines which are equipped with point needles, latch needles or the like.
  • the course of the thread is transverse to the direction of manufacture of the knitted product, so that, according to German usage, a single-thread knitted fabric is used if it has been produced on a knitting machine, or of single-thread knitted fabric if a corresponding knitting machine has been used.
  • Modern knitting machines offer a multitude of possibilities in the design of the stitch product, since the thread course in the manufacture of the stitch product can be varied individually by using appropriate control mechanics or electronics.
  • the control commands are often carried out in the previously known knitting machines using jacquard cards of the knitting or knitting machine. More recently, the control commands using magnetic storage means such.
  • these modern knitting machines can be used to produce knitted fabrics with complicated weaves, different weave patterns, complex color patterns and knitted fabric outlines. From the textile industry also increasingly requires appropriately designed knitted fabrics, whereby due to the short fashion cycles it is important that a template developed by the designer for the shape, binding structure and coloring of the knitted fabric is implemented as quickly as possible in the production.
  • control program is based on a multicolored image template and the specification of the desired type of jacquard or intarsia for the previously selected knitting machine created automatically with the help of the control program computing unit.
  • the control program can be changed in a separately running program in such a way that a predetermined outline shape of the knitted product is taken into account when knitting (form knitting). It is also possible to use weave patterns with more or less complex patterns Binding structures are taken into account, by explicitly entering the corresponding program parts in the SINTRAL program language.
  • a color cartridge is used to represent the binding, with the colors used being assigned to binding elements and modification elements.
  • the binding can optionally also in a thread run display mode or a stitch display type can be played on the screen.
  • the SINTRAL control program can be tested with the help of an analysis program. Detected program errors are displayed for subsequent manual correction by the specialist working on the machine. A change z. B. the thread run by the expert takes place that this changes the SINTRAL control program accordingly.
  • the SINTRAL control program In order to be able to determine the effects of these control program changes on the thread run, the SINTRAL control program must be created completely and a simulation run must be carried out for the previously selected machine type in order to subsequently display the resulting thread run on the screen.
  • the control program computing unit is not able to automatically calculate a control program from a template with several different binding patterns arranged side by side; in this case, the specialist working on this sample system must enter the program steps required for this in the SINTRAL programming language.
  • the invention has for its object to provide a device for developing a control program for a knitting or knitting machine of the type mentioned, in which the implementation of information entered about to be knitted weave pattern in a knitable control program is facilitated.
  • the adaptation unit thus checks the at least two adjacent patterns forming the binding arrangement, be it binding, color and / or outline patterns, within which the entire stitch product or parts thereof, such as e.g. B. sleeves, descriptive overall arrangement. For example, if you start from two knit weave patterns, e.g. B. retrieved from a corresponding library, there is still a knitting incompatibility in many cases if you juxtapose these two patterns in the direction of the stitches. If, for example, a transfer operation follows in one of the two possible directions in one pattern on a common row of stitches, but in the other direction in the other binding pattern, these two operations cannot be carried out in the context of a single sled run.
  • the adaptation unit therefore checks all information about the two patterns, in particular all lines of the thread path representation whether there is such an intolerance. If it detects such an incompatibility, then according to one embodiment of the invention, it corrects the binding information about both binding patterns in such a way that the two opposing transfer operations are carried out in two successive sled runs.
  • the adaptation unit detects knitting incompatibilities which it cannot eliminate automatically, it emits a corresponding error message according to one embodiment of the invention.
  • a particularly preferred further development of the device according to the invention is characterized in that the adaptation unit is designed to transmit the corrected binding arrangement or the error message to the graphics unit for the optical reproduction of the corrected binding arrangement or the original binding arrangement together with the error message, and that the graphics unit is used for manual correction of the each reproduced binding arrangement via the input unit and for transmitting the manually corrected binding arrangement to the adaptation unit for re-checking the knitting compatibility.
  • control program After the interactive completion of a knitted weave arrangement from the several patterns, the control program can finally be calculated, for which purpose the adaptation unit is connected to the control program computing unit for transmitting the corrected stitch arrangement and for subsequent calculation of the control program.
  • control program arithmetic unit have a first subunit for the calculation of a general control program independent of the knitting machine type. It has been found that the wide variety of current knitting machines have a number of essential design features in common. It is therefore common for one that has this. A corresponding control program is therefore created for a "universal" knitting or knitting machine which has these common design features. A machine type-specific control program can now be derived from this universal control program with little effort, the corresponding computer module also being able to be integrated in the respective knitting machine. The centrally developed universal control programs can then be fed directly to the individual knitting machines.
  • the input unit is designed for the independent input of binding patterns, color patterns and outline patterns.
  • the binding pattern or color pattern entered in each case can then be entered or outline patterns can be further revised for each.
  • the binding patterns, color samples and outlines in their final form are then later superimposed on the computer in order to finally obtain the control program for the desired stitch product.
  • the versions of weave patterns, color patterns or knitted fabric outlines developed during this development can optionally be transferred to the corresponding library for storage, for which purpose the input unit is connected to a corresponding data memory.
  • the weave patterns consist of weave rows formed by the weave elements and of weave rows formed by the modification elements, and that the lines of the weave arrangement are formed by the rows of weave patterns joined together.
  • This special type of representation of the thread run is particularly useful for those familiar with the manufacture of knitted products, since the production process is striking in accordance with the runs of the lock.
  • the modification elements such. B. reassignment, throwing off and offset in each case, what is achieved with the corresponding action, but not how this is carried out in the specific type of knitting or warp knitting machine in detail.
  • the display type is therefore independent of the machine type.
  • the number of rows is practically always greater than the corresponding number of rows of stitches, since in many cases the rows of ties corresponding to the rows of stitches of the product are followed by one or more rows of modifications.
  • the thread path representation type can be chosen in a further development of the invention, a symbol representation type, which consists of the individual stitch rows each associated symbol rows, each symbol, the thread guide around a pair of needles and at least part of the subsequent modification operations to be performed.
  • This type of representation has the advantage of being closer to the appearance of the knitted product, even if only a part, preferably only the next modification operation, is also displayed.
  • Another possible type of representation is the stitch representation type, which represents an already quite realistic image of the stitch product to be produced.
  • stitch rows are shown, each of which is assigned to the stitch rows and which are formed from stitch elements, each stitch element representing a stitch image which corresponds to a representation of a corresponding section of the stitch product produced.
  • An advantage of the thread running representation type according to the invention lies in the fact that a general distinction is made between rows of bindings and rows of modifications and that a line is assigned to each forward and reverse of the lock. If two different weave patterns are placed next to each other with a different sequence of weave series and modification series, it must be ensured that all weave series of both patterns are brought to the same height so that they can each form a continuous weave line that can be processed by a single barrel run . According to the invention, this alignment of the binding rows of the two binding patterns is produced automatically by the adapter unit in that the binding row is shifted upwards by inserting blank lines under the relevant "lonely" binding row without connection to a binding row of the other binding pattern until the isolated binding row meets a subsequent series of bonds in the other pattern.
  • a knitting incompatibility can also arise if a row of bonds without an offset of one of the two bond patterns is followed by a row of bonds with an offset (one of the two needle beds) of the other bond pattern.
  • this crossing is fixed by laying the thread in the course of the current weaving line. This leads to a change in the design compared to the two initial binding patterns, which must be avoided.
  • the adapter unit automatically shifts all rows of one of the two weave patterns, so that in the course of this shift the weave row with an offset comes to lie next to a weave row of the other weave pattern, in which no corresponding crossing occurs when one needle bed is shifted.
  • the adaptation unit in turn automatically ensures that after their displacement the binding rows and the modification rows are aligned with one another with the insertion of corresponding blank lines.
  • the shifting of the respective binding pattern takes place until the matching unit determines that no stitch crossing with subsequent fixing occurs in any of the lines. If this goal cannot be achieved, the adapter unit issues the corresponding error message.
  • the adaptation unit In order that the binding pattern to be shifted remains intact, it is expedient for the adaptation unit to shift the binding pattern in one direction at most until the corresponding edge of a further binding pattern or of the overall arrangement is reached. In order to prevent the overall arrangement from being overstepped from the outset, it is proposed that the adaptation unit shift the binding pattern in the direction away from the closest edge of the overall arrangement.
  • the two binding patterns to be matched are periodically constructed in the wale direction (perpendicular to the row direction) with a period usually referred to as the repeat length, it is sufficient to shift the corresponding binding pattern at most until an overall shift corresponding to the greater repeat length of the two binding patterns is carried out is. If a mesh crossing still occurs after this maximum shift, an error message is issued.
  • the binding pattern in question will be shifted upwards, ie towards the end of the overall arrangement to be knitted last, since in this In general, the rows are checked and, if necessary, automatically corrected.
  • the adaptation unit causes the binding pattern in question to be shifted in the opposite direction, i.e. towards the beginning of the overall arrangement. The same applies in the event that there is a binding pattern between the binding pattern and the end of the overall arrangement, the distance to the next binding pattern then being compared with the maximum overall displacement.
  • the adapter unit separates the two corresponding modification rows of the two binding patterns again by inserting an empty row in one of the two binding patterns, which is equivalent to inserting an entire empty row with subsequent resetting of the rows following the empty rows of one of the two binding patterns by one row.
  • the adapter unit preferably sets back the binding pattern by a row whose conversion element “transfer” has a relatively larger transfer distance. It is generally advisable to carry out the more problematic of the two hanging operations first, namely the one with the greater distance, since the stitches are then drawn closer and thus offer greater resistance to a further hanging operation.
  • Another condition for the knitting of several modification elements "cloaks" in a modification row is that of the same direction. If this condition is violated, the adaptation unit again separates the two modification series by inserting an empty line and resetting one of the two binding patterns accordingly by one series.
  • the operation "transferring" is carried out with the aid of thread spreading elements on the needles of the knitting machine. Due to the local conditions, it is cheaper to move to the left in the needle bed grid before moving to the right.
  • the adaptation unit therefore preferably staggered the modification series in precisely this order.
  • a subsequent transfer process can only be carried out if the distance from the start and finish of the transfer process does not exceed a certain limit.
  • This limit depends on whether the binding elements of the pair are moved away from or towards each other at the beginning of the transfer process. In the former case there is a low limit value that is the same for all possible pairs of binding elements. In the latter case, this limit is in the range of twice the distance between the two binding elements.
  • a modification line is then inserted after the reassignment line with reassignment modification elements which undo the reassignment operations carried out when the previously added line was carried out.
  • the adapter unit again issues an error message.
  • the adaptation unit is designed for checking the compatibility of knitting when a color pattern is superimposed on a basic knitted fabric.
  • the adaptation unit preferably again makes an independent correction when it has determined that when the color patterns are superimposed on a basic knitted fabric, incompatibilities occur in the binding arrangement.
  • the adaptation unit itself is not able to remedy the incompatibility, it again issues an error message, as has already been described.
  • the tolerances are preferably carried out one after the other in accordance with the previously explained processes.
  • a particularly advantageous embodiment of the invention in connection with the superimposition of the basic knitted fabric with a color pattern consists in that the color pattern can be selected by knitting types, for example an intarsia or a jacquard knitting type, but also a so-called transparent knitting type.
  • a transparent type of knitting means the following.
  • When partially overlaying a basic knitted fabric with a color pattern usually only rectangular color patterns are provided.
  • those areas that are not to be assigned to the color pattern are knitted in the color of the basic knitted fabric from the rectangular area.
  • These areas for example the outer areas of a heart pattern within the rectangular, adopted color pattern, are therefore knitted in the so-called transparent knitting type, in which these areas practically represent the basic knitted fabric.
  • the type of tying can be selected between two colors during this transition.
  • the type of binding is the type of connection of the color areas with the basic knitted fabric.
  • the position of the binding elements can alternatively be predetermined, but can also be selected automatically, so that the operator of the device need not worry about the choice of the position in this case.
  • the jacquard knitting process is selected as the type of knitting, in this case it is possible in accordance with further embodiments of the invention to choose whether the jacquard knitting area is placed or not placed, in the latter case thus running over the entire basic knitting.
  • a jacquard knitting area placed in the basic knitted fabric it is alternatively possible according to further embodiments of the invention to use the back of the jacquard knitting area as a net, optionally with different net structures, as twill nets or as nets with basic knitted fabric use, with the thread of the basic knitted fabric in the background is continued to train.
  • net In the case of the jacquard knitting, in contrast to the intarsia knitting, a multi-colored back is formed, the term net is to be understood as a knitted structure in which the pattern-forming colored thread is not knitted on the back, i.e. not in the net.

  • the pattern-forming color thread and the non-pattern-forming color thread are knitted 1: 1 on the back.
  • the jacquard knitting area also lies as a so-called cross tube before, which is generated by knitting each non-pattern-forming, ie complementary to the pattern-forming needle on the back, ie on the back needle bed. This creates tubular knitted fabrics, with the pattern-forming and non-pattern-forming threads crossing over when the color changes.
  • all of the rear structures with the jacquard knitting in place to have the sides of the jacquard knitting area in place in accordance with the intarsia binding structure.
  • the jacquard knitting area is not placed in the basic knitted fabric
  • it is advantageous not to knit the back of the jacquard knitted fabric i.e. H. the back has floating threads, or to form as stripes, twill, nets with different net structures or as a cross tube.
  • a stripe back side of the jacquard knitted fabric is to be understood as a structure that comes about by knitting the colored threads present in the pattern on each rear needle, so that when the knitted fabric is viewed on the back side, there is a uniform stripe structure.
  • a preparation of the rear-side binding structure and / or at the end of the jacquard-knitting process is carried out optionally and in a desired manner before the start of the jacquard knitting process, for example in the form that one or more stitches of the basic knitted fabric adjacent to the jacquard knitting area are knitted with the jacquard pattern thread or executed in these stitches of the basic knitting handle of the jacquard area thread will. It is also advantageous if the direction of the thread supply or removal to the color pattern and / or the binding structure provided for the supply and removal of the thread of the color pattern can be selected.
  • a control program for a universal knitting machine or a special knitting machine of a predetermined machine type can be created on the basis of input information such as outline patterns, weave patterns and color patterns including color pattern definitions (jacquard, intarsia, transitions).
  • the input information is not yet such that it can be used to easily calculate a control program that can be knitted.
  • two already knitable weave patterns, e.g. B. retrieved from a corresponding library as part of the facility and arranged side by side in order to create a corresponding stitch product this connection usually brings adjustment problems with it, since the corresponding rows of stitches of both weave patterns are to be produced together during one run of the lock of the knitting machine .

  • This universal control program is independent of the type of knitting machine and can therefore be used for a large number of knitting machines, with the help of an appropriate compiler, e.g. B. can be integrated into the respective knitting machine, a machine type-specific control program is created.
  • the second sub-unit 36 already mentioned above offers the possibility of creating a specific control program for the common types of knitting machine, which is indicated by a block 99. The output then takes place again (output block 100). This completes the program (end block 101).
  • a typical starting situation is shown in FIG.
  • a weave pattern denoted B1 (“Aran”) is to be knitted together with a second weave pattern B2 (“braid”), both weave patterns following one another in the direction of the course MR.
  • the wales direction MS which corresponds to the direction of goods withdrawal, is also shown in FIG. 8.
  • Each of the two weave patterns B1, B2 can be knitted by itself, but not their combination in the weave arrangement 8. This is due in particular to the fact that each line Z parallel to the direction MR, which is symbolized by the two mutually offset rows of the needles 100a of the front needle bed and the needles 100b of the rear needle bed, and that in FIG are shown continuously from left to right, each time by running the lock of the knitting machine. It is impossible to use a row of bonds, e.g. B. in 102 of the left weave pattern B1, and then continue with a pure modification row 104 of the weave pattern B2. All lines Z must either consist entirely of binding elements or consist only of modification elements.
  • the adaptation unit 28 ensures an automatic mutual alignment of the binding rows and modification rows of the two binding patterns B1 and B2.
  • the first line Z1 of the binding arrangement is selected.
  • a subsequent decision block 112 it is checked whether there is a binding row in the binding pattern B1 in the current row Z1, which is the case in the example according to FIG. 8 in the row Z1.
  • the program therefore continues in a decision block 114, which checks whether there is also a binding row of the same color of the binding pattern B2 in the current line. This is the case at line Z1 of FIG. 8, so that the program proceeds to decision block 116.
  • the program then jumps back into the main branch between blocks 110 and 112.
  • the answer in decision block 112 is no for our example, since the second binding row of B1 is a modification row with 4 transfer elements 120.
  • the program therefore continues in a decision block 122, in which a query is made as to whether there is a series of bonds in B2 located. This is the case according to FIG. 8.
  • a subsequent block 124 an empty line is inserted in front of the current line Z 2 in the binding arrangement, with the result that both binding patterns B1 and B2 are raised by one line except for their lowest binding row.
  • the raised rows of B1 are shifted back one row, so that the modification row having the 4 modification elements 120 replaces the corresponding empty elements of the inserted empty line.
  • decision block 116 It is then checked in decision block 116 whether one of the patterns has already been processed; if this is not yet the case, the program jumps back between blocks 110 and 112 via the line advance (block 108). If it is determined during the course of the program in decision block 114 that there is no binding row in B2, although it was determined in block 112 above If there has been a binding row in B1, the subsequent blocks 130 and 132, similar to blocks 124 and 126, ensure that the binding pattern B2 having the binding row is raised in the result until, after the required number of program runs, this Binding series is opposite one binding series of the other binding pattern B1.
  • a knitting problem can occur when two weave patterns are arranged side by side if a weave row BR1, for example weave pattern B1, continues in a weave row BR2 of the other weave pattern B2 For example, offset the rear needle bed to the right, as indicated by the corresponding modification element 134.
  • the two weave patterns B1 and B2 can each be knitted individually, but not the combinations, as shown in FIG. 10b.
  • the offset is carried out, there is a so-called mesh crossing within the area marked with a circle A, which is fixed by the subsequent insertion of the thread. This results in an undesired change in the bond structure of the finished product.
  • Subroutine 74 according to FIG. 18 automatically tries to avoid such crossings.
  • a count parameter n is set to 0.
  • the repeat length r of both the binding pattern B1 and the binding pattern B2 is determined. This repeat length indicates the period length of the periodic pattern B1 or B2 in the direction MS according to FIG. 8.
  • the distance between the top line of the binding arrangement composed of B1 and B2 and the end to be knitted last of the end of the overall arrangement B - total, (defined by the outline read in block 63) is determined.
  • a decision block 146 checks whether a bed offset occurs in the current row, which is determined by the count index n. If this is not the case, then subroutine 74 has been successfully completed. If, however, there is a row of bonds with bed offset in the relevant row, a decision block 148 is next used to check whether an intersection occurs in the other row of bonds (B1 according to FIG. 10) due to this bed offset. If this is not the case, then the program has been successfully completed. If, however, an intersection occurs, a decision unit 50 checks whether the distance to the end of B determined in block 144 is smaller than the larger value of the repeats rB1 and determined in block 142 rB2. If the distance is greater than or equal to the maximum value, ie there is sufficient shifting space, then in a subsequent block 152 a basic formation line is inserted in front of the first binding line of the composite binding arrangement for the corresponding shifting up by one line.
  • the binding pattern B2 is set back together by one line, so that the mutually incompatible binding lines BR1 and BR2 according to FIG. 10 no longer follow one another.
  • the binding series and modification series of the two binding patterns B1 and B2 have to be aligned again, which is caused by a block 156 which calls the subroutine 72.
  • a decision block 158 checks whether the program loop of subroutine 74 has been run through so often that the resulting shift corresponds to the maximum value of the two reports rB1, rB2. If this is not the case, the loop is run through again in a block 160 after the counting index n has been increased.
  • a shift to the beginning of the knitted fabric is carried out by inserting a basic weave line after the last line of the weave arrangement (block 162) corresponding shift of all rows of the composite binding arrangement towards the beginning of the overall arrangement. Then one of the two binding patterns, in particular B2, is advanced by one line (block 164).
  • the subroutine 76 checks the binding arrangement for whether transfer processes with different transfer distances are provided in one line.
  • a line is shown in FIG. 11a with a first modification element "cloaks" 170a, which is followed by a second cloak element “cloaks” 170b.
  • the distance from the cape is approximately twice as great for the modification element 170b as for the modification element 170a.
  • the adaptation unit now creates a knitability by shifting the two weave patterns against one another in such a way that both modification elements are in different lines.
  • decision block 178 it is checked whether the larger transfer process is provided in B1. If this is not the case according to FIG. 11a, the rows of B2 following the inserted line are reset by one row in a block 180. The program then continues in a decision block 182, in which it is checked whether all modification lines of the binding arrangement have been processed.
  • decision block 182 is also passed immediately. If it is determined in decision block 178 that the major reassignment process is in B1, the program proceeds to block 184 in which the rows of B1 following the inserted line are reset by one row. The program then proceeds to decision block 182 and from there via a line advance block 185 back to the beginning between blocks 172 and 174.
  • the first modification line of the binding arrangement is selected in a header 186 of subroutine 78.
  • a check is carried out for the current line in each case as to whether opposing transfer processes are present there. If this is the case, an empty line is inserted in front of the current line in a subsequent block 190 and then in the subsequent decision block 192 checks whether the transfer process "right to left" (184b in FIG. 12) is provided in the binding pattern B1. If this is not the case, as in FIG. 12a, the rows of B2 following the inserted line are reset by one row in a block 194 (with the result corresponding to FIG. 12b).
  • FIG. 13 another knitting incompatibility can occur if a line with both right and left binding elements, that is to say with binding elements which are formed on both rows of needles, is followed by a line with a modification element "transferring", and the transfer process is due to the unfavorable neck direction and neck removal can not be carried out, otherwise the thread breaks when the needle bed is displaced in the transition area between the two needle beds.
  • the modification element "transfer" 210 indicated in line Z6 in FIG. 13 is intended to ensure that the stitch 212 of the rear row of needles is transferred to a needle 214 of the front row of needles. For this purpose, the two needle beds have to be shifted far apart, for example the rear needle bed to the left.
  • transition section 216 of the thread to the right of the stitch 212 is unduly stressed.
  • the other transition section 218 is not overused in this transfer operation because it is at the beginning of the movement is not stretched, but pushed together and even at the end of the needle bed shift (by two needle bed grids) there is still no tension.
  • the situation according to FIG. 13 may have arisen, for example, from the situation according to FIG. 14 a.
  • the weave structure shown here can be knitted per se since the problematic transfer operation (modification element 210) is preceded by another transfer operation, namely a modification element "transfer" 220, which ensures that all stitches are formed on the same row of needles. Since both the direction and the distance between the two modification elements 210 and 220 are different from one another, the corresponding subroutines 76 and 78 already described ensure that the modification elements are arranged in different lines, in accordance with FIG. 14b in such a way that the modification element with the larger one Cape removal comes first; then, however, the undesirable situation according to FIG. 13 is given, since 210 stitches are arranged on both rows of needles when the conversion element is implemented.
  • the lines are interchanged in order to obtain the knitted situation according to FIG. 14c, in which the modification element reassignment 220 is carried out first, with the result that then all stitches are on the back row of needles.
  • the modification element cape 210 can then be implemented without further ado.
  • the lowest binding line of the binding arrangement is selected in a start block 230 of the subroutine 80.
  • decision block 232 it is checked whether there are both left and right education elements. If this is the case, it is checked in block 234 below whether a modification line with a reassignment process follows the current binding line. If this is the case, then the maximum transfer distance U max calculated in the direction of the transfer process, i.e. all connecting sections 216, 218 of the thread between the two needle beds are checked to see whether they are subjected to tension at the start of the transfer process (this generally corresponds to the transfer distance zero) or initially compressed, with the maximum then Cape distance is approximately twice the length of the connecting section. The maximum transfer distance is, of course, the smallest allowable transfer distance in the transfer direction of all connecting sections.
  • a subsequent decision block 2308 it is checked whether the actual reassignment distance corresponding to the ascertained reassignment process is greater than U max . If this is the case, there is a knitting intolerance. In the following, an attempt is then made to remedy the intolerance to knitting. For this purpose, a check is made in a subsequent block 240 as to whether it is possible to interchange the modification line containing the reassignment process with a subsequent modification line. If this is the case, then in a subsequent block 242 both modification lines are exchanged, with the program returning between blocks 234 and 236 for the subsequent rechecking of the maximum transfer distance, taking into account the modification lines preceding the actual transfer process, including the exchanged modification line.
  • a decision block 254 asks whether all the binding lines have already been processed. If this is not the case, then a block 256 is used to advance to the next binding line between the starting blocks 230 and 232 for a new program run until all the binding lines have finally been processed.
  • the program jumps between blocks 252 and 254. This also applies in the event that it is determined in block 134 that the current one Binding line is not followed by a modification line with a reassignment process. This also applies if it is determined in block 238 that the distance of the cape is not greater than the U max .
  • the program proceeds to a decision block 258, which checks whether it is possible to reassign all left elements to the right. Is this the case, then in blocks 250 and 252 a modification line carrying out this reassignment operation is preceded by the modification line having the problematic reassignment process, and a corresponding inverse modification line is reproduced.

  • the preceding line Z6 is a binding line with predominantly left-hand stitches 260, but also an isolated right-hand stitch 262.
  • the connecting section 264 would be stretched too much when the modification element "transferring" 266 was carried out after initial compression, since the transfer distance exceeds the double section length.
  • the subroutine 80 With its steps 246 ff, the subroutine 80 now ensures that a line Z6 'is inserted before the line Z7 with a conversion element “reassigning” 268, which ensures that the lonely right stitch 262 is reassigned to a free needle 265 of the rear row of needles , so that the reassignment operation according to line Z7 can then be carried out.
