The invention relates to a method for manufacturing against warping solid initial rows at flat edge knitting machines, System Cotton, knitted regular right-right items.

In the production of regularly knitted pieces of goods without a double edge or lost initial rows it is difficult to make the first courses so that the leading edge of the fabric looks good receives. As a rule, the first row of stitches is too loose compared to the following knitted fabric, so that it is not possible to use the first row of stitches on regularly knitted double-edged goods to use at all.

This disadvantage was countered by creating a so-called lost edge, which was created by a Separating row was connected to the following item of goods. The lost edge consisted of one Double edge, with the help of which the item of goods was pulled off through the inserted double edge rod, or a piece of right-to-right goods into which the deduction rack was hung.

A beginning of the fabric in 2: 2 or 1: 1 weave has already been suggested for round-edged knitting machines, in which the first row of stitches is formed by all needles, the second, however, only by the Cylinder needles; by offsetting the dial, the dial needle stitches are shifted so that the Pull the first and second row of stitches together and form a good-looking fabric beginning.

Apart from the fact that here only a good appearance of the edge of the goods by turning over the Initial loop series is achieved, there is no difficulty in circular knitting machines, a Withdrawing goods over the row of nets with the pull-off rake attached, because usually no pull-off rake is used.

The object of the present invention is therefore the beginning of the goods on a flat edge knitting machine formed right-right goods so firmly that the beginning of the goods despite removal is not warped by the pull-off rake attached to the row of nets.

On flat knitting machines for right-to-right goods, where the same problem occurs with the formation of the initial rows, two rows or a round tube are knitted after hanging the pull-off rake in the net row, which gives the edge of the fabric a corresponding stability. On flat edge knitting machines, however, if only one needle contour is to be used, only the chair needles can be used and only one row of tubing can be produced with it, as this is used for the process of producing fixed initial rows

Machine needles there is no second row of sinkers.

Another method for producing a fixed beginning of goods on flat knitting machines for right-to-right goods consists in moving the needle beds and before knitting the row of nets after hooking the haul-off rake into the row of nets, the needles are returned to their normal knitting position. The latter method is only used for initial rows in needle stitch patterning Avoid double stitches.

The above-mentioned methods for producing fixed beginnings of goods are customary on flat knitting machines but for flat edge knitting machines due to the special stitch formation by means of a row Sinkers not applicable. It has been shown in particular on flat edge knitting machines that that when using an automatically operated trigger rake the row of nets does not have sufficient stability has, so that the loops of the net row are pulled long by the trigger rake, whereby the result is an excessively loose and unclean edge of the goods.

According to the invention, the above-mentioned object is achieved in that after hanging of the deduction rake in the row of nets formed on the chair and machine needles, the loops of the Transfer the row of mesh every second or third chair needle and machine needle to neighboring needles what is knitted in a customary and desired bond. This can transfer the loops of the net rows of the chair needles in question in the opposite or the same direction as in the machine needles via one or more needles.

It is known in the case of knit-proof goods that stitches transferred onto adjacent needles pull the knitted fabric together, but can do another task to produce knitted fabrics, to give no suggestion for the solution of the present problem.

The invention is described in more detail with reference to the drawings.

F i g. 1 shows a right-to-right product in which the loops of every third machine and chair needle are transferred to the right via two needles in the row of nets;

F i g. 2 shows a right-to-right product in which the loops of every third chair needle in the row of nets over a needle to the left and the loops every third machine needle over a needle are transferred to the right;

F i g. 3 represents a 2: 2 product, in which in the row of nets, the loops every third chair needle over two needles to the right and the loops each third machine needle are transferred to the left via two needles;

F i g. 4 shows the initial sequencing as in FIG F i g. 1 shown as a cartridge;

F i g. 5 represents the initial sequencing for the in FIG. 2 goods shown as a cartridge;

F i g. 6 is the cartridge for that in FIG. 3 start of goods shown;

F i g. 7 shows the cartridge in a modified initial row for a 2: 2 ware.

When producing a solid beginning according to the present method, a row of nets I is first formed with all chair needles S and machine needles M, regardless of whether 2: 2 or right-right goods are to be knitted afterwards. Working the row of nets with all needles is necessary in any case to ensure that the pull-off rack is securely attached and to distribute the pull-off tension evenly over the row of nets. The take-off rake with its needles / 4 is hooked into this row of nets I. The division T of the trigger rake corresponds to the needle division of the machine, but only every second connecting loop between the chair needle and the machine needle can be detected by the hook end of the trigger rake, as can be seen from FIGS. 4 to 7 can be seen. After the pull-off rake is hooked into the net row I, the covering takes place, whereby every second or third chair and machine needle loop is transferred to the right or left to neighboring needles. Through this covering process, the thread is tensioned and the loops are drawn together so that the loops loaded by the individual hooks A of the trigger rake can absorb the trigger tension without being stretched, which results in an unclean appearance and warping of the leading edge of the goods would have. The covering can be done in different ways.

In the case of the one shown in FIG. 1 the beginning of the goods shown were after hooking the pull-off hook A of the pull-off rake into the net row! For example, the loops of every third chair needle S and every third machine needle M are transferred to the right via two needles. After the covering process, rows II, III, IV etc. became right-to-right

ίο worked.

F i g. 4 represents the cartridge to the one in FIG. 1 represents the goods shown.

In the case of the one shown in FIG. The beginning of the goods shown in FIG. 2 were, as in the cartridge in FIG. 5, after the trigger rake has been hooked into the row of nets I, the loops of every third machine needle M and chair needle S are transferred via a needle. The covering did not take place in one direction, but the relevant machine needle loops were transferred in the opposite direction to the relevant chair needle loops, as in FIG. 5 indicated by the arrows.

F i g. 3 and 6 show a further embodiment in which in the network row I the loops every third machine needle to the right and every third chair needle to the left over two needles were transferred. When producing a beginning of goods after the cartridge in FIG. 7 will in the row of nets, the loops every third chair needle and every third machine needle by two Transfer needles to the right. Before row II is cast, the machine needles, from to which the net row loops have been transferred, withdrawn so that they no longer have a thread get and inserted the discard rake for the freely covered chair needles, the one on these needles resulting mesh throws off in the further work process. The series II and following will be knitted in this way in 2: 2 weave.

The machine pictures in FIGS. 1 to 3 are drawn schematically to make the process better can be recognized. These loops of the row of nets run through the ceiling after the Deduction calculation on the finished piece of goods in the II. And III. Row of stitches so that one solid and smooth leading edge of the goods is created.

For the subjects of claims 2 to 4 is only in connection with the subject of the claim 1 protection claimed. Independent protection is not an option.
