Description

The invention relates to a method for producing a knitted part, in particular a bandage, on a flat knitting machine with two opposing needle beds and a stitch transfer device, and a knitted part.

Knitted parts are usually produced on knitting machines, knitting machines being either flat knitting machines or circular knitting machines being used. Each RR knitting machine has at least two opposing needle beds, referred to in a flat knitting machine as a front and rear needle bed, in a circular knitting machine as a cylinder (front needle bed) and Rippscheibe (rear needle bed). Independently of this, the thread or threads are guided with the thread guides and the needles of the respective needle beds of the knitting machine and the knitted body is knitted.

With such machines, different types of threads can be processed. In addition to the usual, the basic knitting threads also elastic threads are processed in certain applications, which give the knitted fabric stretchability. For example, such an elastic thread is processed in the knitting of a cuff, or in the knitting of a body-hugging knit part which is applied to the body of the wearer. Such an elastic thread has a high extensibility and a high return force, wherein usually silicone or elastomeric threads are processed.

Often, however, it is also desired that a knitted part has, at least in sections, on the left side of the goods, that is to say the side facing the wearer or the skin when worn, a light adhesive layer which prevents slippage of the knitted part. In order to provide such a knitted portion, it is customary to sew on or sew on an additional adhesive tape, which usually consists of a textile surface, which is covered with an adhesive coating, for example made of silicone. Alternatively, it is also known to apply directly to the base fabric applications, for example, silicone by printing or gluing, etc. However, these options are complicated, since additional parts have to be produced or sewed on or sewn on respectively applied.

DE 10 2013 022 057 A1 discloses a textile fabric with anti-slip effect. For this purpose, a thread is used, which has a silicone coating. The thread has a thread core of polyamide and a silicone sheath, is consequently not elastic as such. This thread is knitted on the right needle bed, so it is located in the fabric on the side facing away from the skin. Because the mesh heads of this thread are integrated into the fabric and facing away from the left fabric side to avoid excessive exposure of this thread to the skin of the wearer.

In US 6,871,516 B2 is a knit fabric described in which an elastic thread is used, which is inserted only as a weft thread and passes through without stitching.

In US 4,109,492 A is described a stocking that does not roll up in the federal area, this stocking is made on a circular knitting machine.

Finally, in DE 10 2012 004 150 A1 a knit fabric described with different zones in the force-elongation behavior. These different zones are formed by providing different types of bonding of the basic thread in the respective zones. In zones with normal force-strain behavior, the main thread is mostly knitted as a stitch. In zones with increased force-elongation behavior, the basic thread is at least partially knitted as a shortened stitch, tuck and / or floats. The number of tethers and / or floats can be used to vary the elasticity within a zone.

The invention is thus based on the problem of specifying a method for producing a knitted part, which offers the possibility of forming an immediately given Gestrickteilseitig adhesion area.

1. a) Stricken eines Grundgestricks auf beiden Nadelbetten,
2. b) Umhängen einzelner, auf voneinander beabstandeten Nadeln der die linke Warenseite bildenden Maschenreihe des ersten Nadelbetts hängender Maschen des Grundgestricks auf gegenüberliegende leere Nadeln des zweiten Nadelbetts,
3. c) Abstricken von mit Fang oder Masche belegten, zu infolge des Umhängens unbelegten Nadeln benachbarten Nadeln des ersten Nadelbetts mittels eines elastischen Fadens unter Bildung einer Flottung,
4. d) Zurückhängen der zuvor umgehängten Maschen auf die früheren Nadeln,
5. e) Abstricken der zurückgehängten Maschen und der aus dem elastischen Faden gestrickten Maschen mit dem das Grundgestrick bildenden Faden.

To solve this problem, a method for producing a knitted part, in particular a bandage, on a flat knitting machine with two opposing needle beds and a stitch transfer device is intended to realize this by the following steps:

1. a) knitting a basic knit on both needle beds,
2. b) transferring individual stitches of the basic knit hanging from the course of stitches forming the left side of the fabric of the first needle bed onto individual needles of the second needle bed which are spaced apart from one another on opposite needles of the second needle bed,
3. c) knitting off needled or stitched needles of the first needle bed adjacent to needles empty due to the transfer by means of an elastic thread to form a float;
4. d) hanging back the previously transferred stitches on the previous needles,
5. e) knitting the stitched stitches and the knitted from the elastic thread stitches with the basic knit forming thread.

The method according to the invention makes it possible, as it were, to "knit in" an "adhesion area", that is to say that a defined adhesion area is formed solely by appropriate knitting. For this purpose, the basic knit is first formed using a first thread, in which knitting on both rows of needles in accordance with the corresponding predetermined knit weave.

In order to knit the "adhesive area", in the next step, stitches are hanged from one needle bed to needles of the other needle bed. Specifically, individual, spaced-apart stitches of the left side of the fabric, so the fabric inside forming stitch row of the base knit are transferred to opposite empty needles of the other second needle bed. This is done by means of a corresponding stitch transfer device of the knitting machine. Depending on the knitted binding, as in a 2 × 1 patent bond, every 2nd stitch (= 3rd needle) is transferred.

In the following step, the needles or stitches of the basic knitting yarn, which are empty as a result of the transfer of needles of the left side of the needle forming the first needle bed are knitted by means of an elastic thread to form a float with stitch. The elastic thread is thus knitted with a stitch on those needles that are right and / or left of a now empty needle, because previously suspended loop. The elastic thread then extends in each case with a floatation of stitch to stitch, wherein the float extends, for example, in a 2 × 1 patent bond over two needles, but any conceivable combinations are possible.

Then, in the next step, the previously transferred stitches of the basic knit are hung back onto their previous needles by means of the stitch transfer device. This back hanging is almost against the flooding.

In the last step, the stitched stitches and stitches knitted from the elastic thread are knitted with the stitch forming yarn, after which the steps b - e (repeat) can be continued until the "sticking area" has the desired width and is knitted. This may be followed by a knit of any binding, or the knit may end with the knitting in step e). The more often the repeat, ie steps b) - e) are repeated, the wider the knitted "sticking area" becomes. A narrow "adhesion area" can theoretically be formed by carrying out steps b) - e), ie only one row of stitches.

By hanging the stitches, the knitting of the elastic thread on needles of the left side knitting needle bed with floats and hanging back is achieved that knitted by the floats the suspended stitches respectively the stitches in the field of floats with the textile knitted fabric be pressed by the restoring force of the elastic thread in the fabric. In contrast, the knitted with the elastic thread on the first row of needles stitches are virtually sublime, so that the elastic thread emerges on the left side of the fabric or the fabric inside. The emergence of the elastic thread is particularly assisted when the needle on which a stitch of the elastic thread is knitted, is previously covered with a catch. Because the catch increases quasi the thread volume, so that the stitch of the elastic thread protrudes a little further.

In this way, it is thus ensured that on the one hand directly on the goods side, the skin side, sufficient amount of elastic thread material is present, so that the easily adhering property of the elastic thread, such as a silicone or Elastanfadens, can be exploited to a to ensure good adhesion to the skin of the wearer. At the same time adjacent stitches formed by the textile knitting thread, pressed by the floats of the elastic thread in the fabric interior, so are not on the skin side and therefore reduce the adhesion of the knitted "adhesive tape" not. This ensures that a very good adhesive contact can be achieved solely by appropriate knitting of the elastic thread in the manner described. It is no longer necessary to provide an additional adhesive tape or the like to form the adhesive area.

Preferably, the needles, which are knitted with the elastic thread with mesh, previously occupied only with a catch, which as described does not form its own mesh but merely increases the "thread volume" on the needle, which causes the elastic thread something Continue to emerge from the knitted fabric. This also means that from stitch row to stitch row always the elastic thread prominently emerges. Nevertheless, the needle could also be covered with a loop of the textile basic knitted thread. In this case, the stitch of the textile thread and the elastic thread would alternate in terms of stitches, as it were, from one course to the next. Seen in the longitudinal direction means the occupation with the Fang that quasi a closed line (wales) of elastic thread stitches on the fabric inner side forms, while occupying a textile stitch from the basic knitting yarn from stitch row to stitch row a change from textile thread and elastic thread would be seen in the fabric longitudinal direction.

In a development of the invention, it can be provided that at least one, preferably at least two, needles lie between two stitched stitches. Depending on how many needles intervene, the length of the float and consequently the distance of the "rows of stitches" seen in the fabric transverse direction from elastic thread meshes.

As described, in the last step of such a knit weave is knitted with the basic knit thread. This can be done by knitting the needles knitted with the elastic thread either with a catch or with a stitch, while the needles are knitted with the stitched stitches with stitch. The difference whether a catch or a stitch is knitted with respect to the emergence of the elastic thread stitches is already explained above. The needles with the stitched stitches are preferably knitted with stitch, since this stitch is in turn umgehängt in the next process cycle, thereby ensuring a smooth process. With suitable thread material, the touristic use of the binding elements floats and / or catch on this needle is also conceivable. It is useful if, when knitting according to the last step with the basic knitting yarn forming the stitches of the opposite needle bed are knitted.

It is conceivable to knit only one needle at a time with the elastic thread. That is, each float runs from a single stitch to the next single stitch. Alternatively, it is also conceivable that two adjacent needles are knitted with the elastic thread. In this case, both needles would be covered with catch or stitch of the base knit. Overall, then arise wider rows, seen in knit cross direction, made of elastic thread.

In a further development of the invention it can be provided that the stitches are distributed over the entire width of the base knit in pattern distribution. Alternatively, it is conceivable to relocate the stitches only in individual areas of the basic knit. This makes it possible to form the protruding rows or areas of elastic thread only partially, so that the adhesive effect is only partially effective, for example, to be able to sew easily over this area or to localize the adhesion locally, etc. In areas where no hanging Consequently, there is no float, which could hold back the knitted stitches with the basic knitted thread or would press into the fabric inside. Rather, the knit stitches appear in these non-overhanging areas and form the fabric inside. A significant adhesive effect is not given in this area. The stitches, knitted with the elastic thread, step back, they pull into the fabric, the adhesive effect in this area inevitably decreases. This means that patterns can be redistributed in a pattern, and / or in blocks, in order to only partially infiltrate the "adhesive tape".

The elastic thread used is preferably a silicone or elastane thread. In principle, if the knitting machine is configured accordingly, it is possible to work with "bare", ie, unbound, silicone or elastane threads. Preferably, however, an elastic thread wound around a fluid-soluble, in particular water-soluble binding thread is used. Such a binding thread reduces the friction of the otherwise easily adhering silicone or Elastanmaterials on the stitch-forming elements (needle, thread guide, etc.) and the thread feeder (feeder, thread tensioner, thread brake etec.). For example, a binding thread made of "Solvron®" is used, which is water-soluble. This means that the knitted part must be washed after knitting, which causes the water-soluble binding thread to dissolve and the adhesive properties of the silicone or Elastanfaden fully come into effect.

Finally, it is conceivable to insert an elastic weft before or after the knitting with the elastic thread. This weft thread, which can be inserted, for example, when a compressive knitted part is to be knitted, does not affect the function of the "knitted adhesive tape" in any way.

In addition to the method, the invention further relates to a knitted part, in particular in the form of a bandage, produced by the method of the type described above.

A knitted part according to the invention, in particular a bandage, consists of a thread forming the base knit and an elastic thread knitted at least in sections, wherein the elastic thread is knitted, knitted and raised in at least a part of the courses running in the fabric transverse direction on the left side of the goods with stitch, wales and on the left side of the goods knitted adjacent stitches of the basic knitting yarn by one with respect to the left side of the fabric in front of the stitches lying flotation of the elastic thread are pressed into the fabric interior.

The basic knit is preferably knit with a 2 × 1 patent bond. The binding shown in particular in the following figures in threadline ( 1 ) and mesh image ( 2 ) of a 2 × 1 patent, however, serves only as an example, other binding variants based on the presented mode of operation (highlighting stitched knitted with elastic threads and pushing back the stitches knitted with classical thread material by floating the elastic thread) are of course possible.

Further advantages and details of the invention will become apparent from the embodiment described below and from the drawing. Showing:

• 1 a diagram illustrating the thread pattern for explaining the method according to the invention, and
• 2 a representation of the mesh image of the left, facing the body side of a fabric part of the invention.

1 shows in the form of five partial diagrams a) - e) the thread course of the different, an inventive knit part forming threads.

Knitted is supposedly on a flat knitting machine, which is a rear needle bed 1 and a front needle bed 2 having. Knitting is on the one hand with a classic, the basic knit forming knitting thread 3 For example, from wool, cotton, polyamide, viscose, polyester, acrylic, etc. Furthermore, with an elastic thread 4 Knitted, for example, a silicone or elastane thread, which is optionally provided with a water-soluble binding thread.

Diagram a) shows the home position and the offset home position. On the back needle bed 1 is the left side of the fabric, so the knitted interior side, which faces the wearer knitted, while on the front needle bed 2 the knitted outside is knitted.

Every needle bed 1 . 2 has a large number of individual needles 5 . 6 Depending on the knitting technique to be knitted or stitched or unoccupied. In the example shown it is assumed that a 2 × 1 patent bond is knitted. Obviously the basic knitting thread runs 3 both around needles 5 of the rear needle bed as well as needles 6 of the front needle bed. In the example shown, the needles are each 5a of the rear needle bed with a catch 7 of the base knit thread, while the needles 5b of the back needle bed with a stitch 8th are occupied. The remaining needles 5c are not occupied.

On the front needle bed 2 are the needles 6a each with a stitch 9 of the base knit thread, while the needles 6b are free.

In the next step, see diagram b), which shows the beginning of the report, the stitches become 8th from the needles 5b of the rear needle bed 1 on the needles 6b of the front needle bed. So you are now on the front needle bed 2 ,

In the next step according to diagram c) the elastic thread is 4 knitted. This will be done on the needles 5a with the catch 7 each mesh 10 knitted, as the diagram c) clearly shows. Otherwise, the elastic thread is 4 afloat, that is, between two stitches 10 one float each 11 given is. This float 11 extends in the case of the 2 × 1 patent bond shown here over two now due to the hanging of the stitches 8th empty needles 5b and 5c ,

In the next step shown in diagram d) are the previously transferred stitches 8th from the needles 6b back to the needles 5b of the rear needle bed 1 reassigned. This transfer is almost against the floating elastic thread 4 according to step c) on the first and rear needle bed 1 is knitted.

In the last step according to diagram e) the textile basic knitted thread will be redone 3 knitted, with him again the same needles 5a with a catch 7 respectively. 5b with a stitch 8th respectively. 6a with a stitch 9 are knitted as shown in the basic offset position according to diagram a). This means that the diagram e) ultimately represents the end of the repeat, but at the same time also the starting situation for the beginning of the repeat according to diagram b).

The steps according to the diagrams b) - e), which correspond to the method steps b) - e) according to the invention, and which represent the repeat, can now be repeated as often as desired. The more they are repeated, the wider the knitted "sticky area" becomes. A narrow adhesion area can also be formed only by such a row of stitches. The conclusion may be made by the Abknicken according to step e), or it may be followed by any other knit section with any binding.

By hanging the stitches 8th is the each umgehängte stitch when knitting the elastic thread 4 in relation to the left side of the fabric, that is the knitted interior side forming stitch row of the rear needle bed 1 offset to the knitted interior. That means that the float 11 the elastic thread 4 in relation to the fabric inside in front of the stitched stitches 8th that is, the part of the basic knit that is between the stitches 10 from the elastic thread 4 lies, is arranged. This now leads to the fact that the floatation on the finished fabric part 11 the stitches 8th pushes in the direction of the knitted outside, so pushes them into the knitted interior. In contrast, highlighted to the left side of the fabric, so the fabric inside, are the stitches 10 elastic thread on the back needle bed 1 knitted. That is, directed to the fabric inside much elastic thread material is given. Since the elastic thread, be it the silicone thread, be it the elastane thread, has a corresponding adhesive property and there the stitches 10 highlighted or raised lie results from this consequently a corresponding adhesive area, the only given by the knitting in the longitudinal direction given courses from the stitches 10 the elastic thread 4 is formed. The adhesive properties are remarkably good as they are pushed back by the stitches 8th are not affected by the non-adherent basic knitted thread.

The finished fabric part results in lengthwise wales seen in the longitudinal direction of the fabric 12 out of the stitches 10 , adjacent to those, more or less engrossed in knitwear, the floats 11 the elastic thread 4 and behind them the wales of the stitches 8th and 9 (seen in the fabric longitudinal direction) of the basic knit lie.

An exemplary mesh image of the left, ie to the body-facing goods side, so the fabric inside, in the form of a 2 × 1 patent bond is in 2 shown.

Shown are the stitches 10 from the elastic thread 4 , seen in the longitudinal direction, longitudinal, raised wales 12 form.

Shown are the corresponding catches 7 of the textile basic knitted thread 3, on which the stitches 10 the elastic thread 4 are knitted.

Between the wales 12 respectively the stitches 10 the floats run 11 the elastic thread 4 , These lie to the fabric inside out directed above the knitted outer side seen behind mesh 8th and 9 , The stitches 8th are the stitches that are on the back needle bed 1 were knitted and moved back and forth while the stitches 9 the stitches are on the front needle bed only 2 knitted. Due to the restoring force of the elastic thread 4 in the field of flooding and the formation of the mesh 10 , knitted on the catch 7 , lie the wales 12 exalted with respect to the level of the floats 11 so as to give rise to a raised rib structure passing through the elastic thread 4 is formed.

Is as an elastic thread 4 used a thread wound with a water-soluble binding thread, so it is necessary after the production of the knit part to wash it, so that the binding thread dissolves and the respective silicone or Elastanfaden then merely lies.

Although the embodiment each shows a 2 × 1 bond, it is equally conceivable one kind 1 To knit × 1 binding. In this case, there would be between two wales 12 only one wale, formed (seen in Knitting) from the stitches 9 , on the needle bed 2 If you want broader ribs on the right side of the fabric, ie the side of the fabric facing away from the body, you increase the number of wales out of the stitches 9 on the needle bed 2 , Likewise, the ribs on the needle bed 1 , left side of the product towards the body, be widened by increasing the ribs from the catch 7 in suitable combination with the wales out of the stitches 9 on the needle bed 2 and the subsequent knitting by stitches 10 with the elastic thread 4. By increasing the number of stitches 8th on the needle bed 1 and the corresponding free needles 6b on the needle bed 2 The width of the float can also be determined 11 increase.

In principle, it would also be conceivable, instead of a wale 12 two such wales per width of the knitted part 12 train. In this case, in the step according to diagram c) would have on two adjacent needles 5 of the rear needle bed 1 the elastic thread are knitted. This would result in the sum of slightly wider rows of stitches through the parallel adjacent wales 12 , This means that there are also variations in this regard.

Finally, of course, there is the possibility, depending on the chosen type of binding not just a scam 8th umzuhängen, but for example, two such stitches, the left and right of the needle to be knitted with the elastic thread lie. Also in this regard, therefore, a possibility of variation is given. In addition, of course, at any time a procedural step can be inserted, with the needles on the front needle bed 2 additionally knitted, for example, to form a pattern, etc.

The adhesion region according to the invention can be knitted on any base or base knit section. For example, in a bandage first the tubular knitted body, z. B. knitted as a compression knit, after which the adhesive area is knitted using the method according to the invention. Of course, such an adhesive region may also be provided on both knit dividend ends, as it may theoretically also extend over the entire length of the knit part.
