The invention relates to a method for knitting stockings on multi-system circular knitting machines and relates to the perfect formation of a loose chain of loops in a stocking, in where the stocking tip is knitted in multiple systems in a pendulum gear.

The knitting of stockings on circular knitting machines, both in the circular walkway and in the Working with multiple systems has the advantage that the production speed increases will. So far it was necessary in two-system knitting of a stocking tip that on The part of the stocking that follows the stocking point and contains the loose chain of loops is also two-system to manufacture. To this extent, a difficult problem has arisen for the chain of loops of such a stocking result than the loose stitches forming the chain row necessarily only on one of the two Systems have been made to achieve a single course of loose loops. The two-system The worked chain row therefore has a crack in a wale where two loose stitches one after the other in the direction of the stitches in the direction of the wale are separated by a single stitch. This leads to a thickening of the warp seam and also easy to make mistakes when opening the loose stitches of the chain of warps onto the needles of the warping machine, as explained below:

In the case of very thin knitted fabrics, e.g. B. wafer-thin stockings, for their production, for example, four hundred Needles are required in the needle cylinder, the meshes are extremely small, and it It takes a lot of practice to open the stitches for linking onto the needles of the linking machine. This process is facilitated by the loose row of loops, which serve as a guide for the worker. It is essential that one stitch of each wale is opened on a needle of the linking machine otherwise a ladder will be created immediately. The purpose of the chain is to provide the To close the hose opening and to secure the end meshes against the formation of runs a warp seam that is completely smooth and essentially invisible in the finished stocking.

If only one system is knitted when forming the loose row of stitches used for linking, whereby the loose stitches must extend over a circumference of slightly more than 360 °, so that two loose stitches are superimposed in some wales, there is no difficulty in opening the loose stitches on the needles of the method of knitting stockings

Linking machine, because the loose stitches at the point where they overlap in successive Rows lie and to the worker in appearance and effect as continuous simple ones Row of loops appear.

If, on the other hand, when forming the loose chain row again with the necessary overlap with two Systems are knitted, the loose stitches are at the point of overlap with an intermediate row separated by small meshes. Burping the loose stitches is no problem until the Overlap area is reached. There, however, the worker is faced with the question of whether either the above or the lower loose stitches, between which the small stitches of an intermediate row lie, on the Needles of the linking machine are to be pushed open. The row of loops makes in the overlap area a jump that extends over two courses. In the overlap area exists therefore, because of the spacing of the loose stitches, a high probability that one or two Wales are left out when burping, so that runs easily form there can. Furthermore, when belching occurs in the overlap area because of the transition from the a fold in the knitted fabric from the top to the bottom loose stitches across the intermediate row, and this fold is included in the warp seam, creating a noticeable and unacceptable local Thickening arises that looks like a bug.

To avoid these difficulties and disadvantages, knitting according to the present invention is

Since the invention only relates to the production of concentricity, the successive locks of the loose chain row following the two parts 42, 44 and 46 are used. These needles are extended in the systemic knitting of a stocking tip, the same knitting is then through the lock parts 50 and 52 in the Drawing only lifted so much from the knitting machine, of which the cam lock part 52 shows the needles and in the following description 40 lifts them into the locked position before they approach the explained, than the left-hand cam lock part 60 necessary for understanding the invention. A lock part 48 is manoeuvrable. In addition, the machine can be designed and work in the usual way on the right-hand side for lifting needles. In particular, the system during the backward stroke in the pendulum gear can specialize with only slight deviations whereby it lifts the needles after they have been switched off and described by the machine which is shown in the German patent 885 905 and shown in succession. have been drawn. In this patent specification, a knitting machine is open - the needles are in the locked position at the back bit, with the stockings continuously including the wärtshub in the pendulum gear. Furthermore, there are lock parts of the pendulum heel and toe 62, 64 and 66, which are radially movable, are knitted in two systems and in which the 50 of these are the lock parts 64 and 66 in the loose chain row is formed in two systems.

of the same length, but of different lengths, and are corresponding to F i g. 2 distributed.

If you look at the needle butts as they are moved in circular knitting, the leading ones have Short toe needles 86 have a foot length of 7.6 mm. The needles 88 connect to this group of needles with a foot length of 6.9 mm, and this in turn is followed by the needles 90 with a foot length of 6.1 mm. This group is followed by the needle groups 92 and 94, the feet of which are again one 6.9 mm and 7.6 mm in length.

The first group 96 of the long foot needles has feet with a length of 8.6 mm, while the foot length of the next group 98 is 9.9 mm. The middle group 100 of the long-toed needles is a foot length of 8.6 mm, while the feet of the following group 102 again 9.9 mm and those of the last Group 104 are again 8.6 mm long. These dimensions are not binding and can be changed if necessary but they indicate the ratio of the foot lengths that are switched on in the operation are. The meaning and application of the different foot lengths results in general from the specified Patent specification. In the present case, group 102 is primarily important. In particular The connection of the pattern pusher with the needles of this group 102 also plays a role. the Pattern pusher in general and for some of the leading needles in Group 102 are short-legged 14 provided. Of these leading needles in this group are the first needle and the following ones Needles alternately assigned pattern pusher with long feet 16, while the intermediate Needles are each assigned to pattern pusher, which have short feet 14. The number of model pusher with long feet is open and can be chosen, but in general it is convenient that at least three or four sample pushers with longer feet 16 are switched on. As will be explained later is, this arrangement is particularly with regard to preventing the formation of eyelets Made the transition from two-system to one-system knitting.

F i g. Figure 3 shows a stocking made according to the invention. With the exception of the area of The sock is as usual and can have different shapes. In cases where the present invention is applied, namely in the two-system knitting of stocking laces, the stocking would usually be knitted consistently in two systems or with the only one Except for the beginning rows. The stocking has the stocking edge 106, the leg, in the usual manner 108, instep 110, high heel 112, heel 114, molded sole 116 and toe 118, all of which can be produced in the manner described in said patent specification. the However, the invention is also applicable to stockings in which some of these parts are omitted or in other shape are formed. For the knitting disclosed in the cited patent it is It is essential that the heel 114 with the short-toe sole needles, but the tip 118 with the long-toe tensioning needles is knitted. The warp seam is accordingly on the underside of the foot.

However, the invention is also applicable to the knitting of stockings in which the warp seam is attached The top of the foot is because the toe is knitted in two systems with the sole needles. The necessary Changes are without further explanation from the following description of the How it works is understandable.

Since the knitting is carried out in the usual manner except for the completion of the tip, the description is the mode of action below is limited to the operations that are related to the completion start the last backward stroke of the needle cylinder as required by the stocking tip. At this time the lock parts 62, 64, 66, 30, 34, 32, 28 and 80 are moved out of their operative position, and knitting is done with the long-footed needle groups while the short-footed needles are held up and are idle.

On the last backward stroke of the needle cylinder, through which the stocking tip is completed and are knitted in the two courses, the switch lock part 28 is fully turned on, and the Groups of long-footed needles are at the same height as they are raised above the lock part 36 results under him. At the end of this stroke, all long-footed needles have passed the lock part 36, while the needles of the short-foot groups are located above the cam lock parts, with the leading short-footed needle during this backward stroke a position close to the key switch part 28 reached.

When the needle cylinder begins to rotate forward again in concentricity, the lift lock part becomes 48 withdrawn. The long-footed needles, which are caught by the lock part 36 on the last backward stroke have been raised, are now lifted by the lock part 38 and in the locked position lowered by the cam parts 42 and 44, taking up yarn on the right-hand thread feeder and entangle when they go down on the gate lock part 46. You will then go through the Lock parts 50 and 52 raised and take yarn on the left-hand thread feed when they go down on the cam lock part 60; they knit a second row of stitches. Then will the needles are raised again to catch height by the lock part 61. During this movement that becomes Intermediate ram lock part 74 withdrawn.

With further rotation of the cylinder, the short-footed needles are lowered by the switch lock part 28 and follow the knitting path taken by the long-footed needles. However, while the Group 90 needles, the feet of which are 6.1 mm long, go over the lock part 36, this is withdrawn. Likewise, the lock part 38 is withdrawn, so that the remaining short-footed needles get from the lower end of the switch lock part 28 directly to the lock part 40, his occupies upper position. However, since the short-footed needles are raised to the external operating position have brought their old stitch under the needle tongue before working the tip, this is useful Lock part 40 only for their lifting before they take up yarn on the right-hand thread feeder.

If the group 100 long-footed needles have the

Pass lock part 62, this is moved inward so far that it is just the 8.6 mm long feet of the Group 100 no longer detected, and if it lowers needle group 102 with a foot length of 9.9 mm, it is moved completely inward to lower all subsequent needles.

When the long-footed needles come around again, will. The yarn finger will be on the right-hand thread needle groups 96, 98 and 100 from the feeder are raised as soon as the last needle is reached The lock part 61 is guided at the catch height and has taken up follow the yarn; the laid out yarn will Path the short-footed needles have taken. Then put them through the usual thread clamping and cutting the two-system knitting clamped by lifting 5 device and cut. Soon after this Needles through the lock part 40 up to the enclosed position of the pattern pusher through the lock part 80 away, where they have then been lifted and their intermediate pushers on the knit both systems. Lock part 74 have passed, the lock

Before the guide needle of the group 102 reaches the part 80 and the lock part 74 in the position of the ready position together with the pattern pusher 8 for the optional lifting of the working lock part 80, this needle is moved into the locked position, like the lock part in its operative position later required to act on this,
moves the long feet 16 of the sample pusher. Just before the point in time at which the first through the corresponding intermediate pusher 6 needle of the group 96 reaches the coulier point of the coulier with their feet 12 over the point 78 of the lock part 60, this gate lock part 76 is raised, which in turn the first lowered to start the loose chain row; it remains needle of group 102 and then alternately in this lowered position somewhat longer than one revolution of the needle cylinder provided with long feet 16 pattern pusher, whereupon it is raised to its normal position again in assigned needles of this group to catch height after they are raised. The other needles of group 20 loose chain row only finished on this one system, but are not raised and left in place. If desired, the loose Kettelben can thus be lowered to the level to which they were lowered by the series of half a cylinder turn later, the lock part 62; they will only be lifted by the cam 50 on the leading needle as the cam group 86 begins. If necessary, it can still begin part 48, as mentioned above, withdrawn 25 later. After some rows of stitches have been made. The shoulders 20 of the raised one-system pattern pusher 8 that follow the loose chain row touch the cam 76 and are knitted, the machine can go through again as follows, after they have been partially lowered by this back to two-system knitting The yarn finger on the right-hand thread feed, which is in a position in which it is lowered, brings the yarn on both the feet 14 and the feet 16 in a position in which it is lowered which it acts through the first raised. Attach the needle for knitting to this thread feeder.

The raised needles of the group 102 that is picked up. The lock part 62 can be partially lifted in this way by the pattern pusher at the catch height of the last long-footed needle, follow the needles of 35 be withdrawn, so that the group 100 short-footed needles on the containment lock part 40; as soon as group 90 is no longer recorded. While this but the last needle of group 100 is passing the tip of the needle, it can be fully retracted and reached lock part 40 and its old stitch under, so that the first needle of group 90 and the tongue has brought the lock part 40 to the following Needles are lowered to the gate lock part 46 catch height, so that although some of them are approaching the catch height and so no yarn on the needles raised alternately to the right can still be picked up in the one-sided thread feed. At the point where the closed position is raised, the remaining needles at which the two-system knitting begins, it will remain in the catching position, moving the thread lock part 81 so that the lower ends of the thread feeder on the right-hand side are fed and the pattern pusher 8 swings out so that their feet stop and take in. Since the intermediate 45 ends 85 come into contact with the lock part 83 and all following needles are men through the lock part 62 and are raised by it, whereby the are lowered, they go under the lock part 40 corresponding needles into the locking position on the right-hand thread feeder by, so that if the intermediate pushers 6 are not lifted onto the lock part 74 by them, the yarn at this thread feeder is not raised. The leading, take. All needles of the group 102 are brought together on the lock part 50 to grip the needles that have been raised into the enclosed position. As soon as this then the waiting yarn at the right-hand thread inlet, the needles that have been picked up at the right-hand feeder that have not picked up any yarn through all of the following thread feeders, the needles will be knitted. An eyelet that is raised when the thread end is worked in.
