Description

The invention relates to a method for producing a knitted item on a flat knitting machine with at least one first needle bed in which needles are arranged so that they can be driven out by a knitting system, at least two self-sufficient thread guides and a knitting system, the thread guides and the knitting system being movable parallel to the longitudinal direction of the needle bed .

From the EP 1 724 385 A1 a method for producing intarsia knitting is known, wherein a thread guide is brought back into an inactive position after the end of his knitting area and when the system is changed to his color field. In this way it is avoided that it obstructs the thread guide, which forms the subsequent color field, or that the thread fed by it is caught by needles driven out in the following system. The movement of the thread guide takes place between the knitting systems.

Flat knitting machines with self-driving yarn guides are known. In these flat knitting machines, each thread guide has its own drive. This has the advantage that the thread guides can be stopped exactly at any area of a row of knitting. In particular, self-sufficient thread guides can be driven and moved independently of a knitting system and independently of one another.

So far, flat knitting machines with self-driving yarn guides have been used essentially for the production of intarsia knits, in which the boundaries of the color fields are adhered to with the exact mesh. Possibilities of using flat knitting machines with autonomously driven thread guides for other complicated knitted fabrics have not yet been shown.

The object of the present invention is to provide further method variants for the production of knitted pieces with self-sufficiently driven thread guides.

This object is achieved according to the invention by a method having the features of claim 1.

If intarsia ropes are to be produced on flat knitting machines and the flat knitting machine does not have an independently driven thread guide, the color fields must be spaced between the systems, otherwise the thread can be caught by the expelling needles when the intarsia thread guide is swiveled in. With the method according to the invention, intarsia knits can be produced on flat knitting machines without maintaining a distance from color field to color field. Besides, it is possible to produce intarsia ropes with just one knitting system. This results in faster production times. Color field distances do not have to be taken into account when creating the sample.

The thread guide or guides are preferably movable not only parallel to the longitudinal direction of the needle bed, but also perpendicular thereto.

By changing the position within a system according to the invention, thread guides in the offset can be influenced in such a way that the following thread is not inserted into a needle hook and thus a float arises. This also makes it possible to produce a filigree knit. With the self-sufficient thread guide, the thread material can be placed in the needle hook or behind the needle (float) by optionally moving the insertion point in a system. Thus, a distinction can be made between thread insert and / or float via the thread feed and without lock modification. Filigree or Devoré knitting patterns can be realized as desired without preparatory measures to convert a knitting lock using self-sufficient thread guides. Combinations with inlay, structure, jacquard or other bindings are possible without any problems.

A thread is inserted through the second thread guide into the needles of the second area driven out by the knitting system. A color field can thus be produced directly adjacent to another color field.

According to a further variant of the method it can be provided that the thread of the second thread guide is the thread of the first thread guide wraps around. The second thread guide can move into the color field of the other thread guide in order to realize the looping.

The color field generated by the first thread guide and the color field generated by the second thread guide can be connected by knitting with the first thread guide up to the needle into which the thread of the second thread guide is inserted after step b. is involved. In this way, intarsia ropes can be produced with no distance between the color fields.

According to a variant of the method, the color field generated by the first thread guide and the color field generated by the second thread guide cannot be connected by knitting with the first thread guide up to the needle into which the thread of the second thread guide is knitted after step b. is involved. This procedure can create an opening in the knitted fabric. For example, a cutout, a buttonhole or a neckline can be generated in this way.

In step a. In addition, the second thread guide can be used to insert thread into the driven needles of the first area, the first following the second thread guide. Thus, a knitted area can be clad. If then only one thread guide is used to knit, only one monofilament thread can be knitted, for example. Then both thread guides can be used again for knitting, so that an area is plated again. In this way a filigree knit can be produced. For this purpose, the trailing thread guide can catch up after a predetermined number of needles and also insert thread into driven needles. Furthermore, it can be provided that a The thread guide runs along in the knitting area of the other thread guide. The thread guides can create stitches, tucking, floating, splitting or even plating in interaction. It is also possible to change the thread guides in the up / down position. A driving offset can also be set. Reversible cladding in one system is possible.

The method according to the invention can also be used to knit multigauge if two or more thread guides knit in one color field, only the pattern thread guide in the color field edge stitch makes a connection or does not make a connection and then knitting is continued with the thread guide of the adjacent color field. Furthermore, additional yarns, rubber threads, wires, stabilizers or similar material can be introduced.

With the method according to the invention it is possible to knit an opening, for example a V-neck or a slit, in a knitting system. In terms of binding technology, novel variants are possible by plating inlaid edge meshes, e.g. B. in one carriage direction, and binding in the sinker mesh in the other carriage direction. It is also possible to insert only one thread guide into the weave in plating patterns with two or more thread guides per color field.

In the following illustrations, the front needle bed is labeled V and the rear needle bed is labeled H. The needles of the front needle bed V are marked with capital letters, while the needles of the rear needle bed H are marked with small letters.

According to the Fig. 1a loops are formed on needles A to G of the front needle bed V with a first thread guide. The thread that is guided through the first thread guide is identified by the reference number 1. After the loop has been formed on the needle G, the first thread guide is brought out of needle engagement by being moved against the knitting direction. A second thread guide is brought into needle engagement. The thread 2 of the second thread guide wraps around the thread 1 of the first thread guide. The second thread guide moves into the color field of the first thread guide. In particular, it moves at least one needle over the position of the first thread guide. This is in the Figure 1b shown. As evidenced by the Figure 1c 2 stitches are made on needles H to K with the second thread guide and the corresponding thread educated. Reference number 3 shows the position of the first thread guide after it has been moved against the knitting direction. It is thus possible to produce an intarsia knit with just one system. No color field gaps need to be taken into account when creating the sample. The thread of the second knitted field or color field is enclosed between the edge meshes of the first color field.

In the knitting sequence according to Figures 2a to 2c are initially according to the Fig. 2a formed on the front needle bed V with the thread 10 guided by a first thread guide on the needles A to E loops. The thread guide 11, which guides the thread 10, follows the needles A to E. When the last needle E to be knitted has inserted the thread and is pulled off so far that the thread is securely in the hook, the thread guide 11 becomes so wide shifted against the knitting direction so that the needles F to 3, which are driven out, cannot grasp the thread. A second thread guide 12, s. Figure 2b , also moves against the direction of knitting and inserts its thread 13 into the needle E. Then the needles F to J are knitted in the same system as the needles A to E with the thread 13 of the second thread guide 12, see FIG. Figure 2c . The color field formed by the first thread 10 and the color field formed by the second thread 13 are thus connected.

The Figures 3a to 3d show a similar knitting pattern. First of all, the first thread guide 11, which guides the thread 10, is used to knit with needles A to E on the front needle bed, thereby forming loops. When the last needle E to be knitted has inserted the thread 10 in its area and has been withdrawn so far that the thread is securely in the hook and the needle tongue is closed, the thread guide 11 is shifted against the knitting direction until the needles F to J that have been driven out cannot grasp the thread, s. Figure 3b .

At the same time, another thread guide 12 moves into the knitting position, s. Figure 3c . The needles F to J are then knitted with the thread 13 of the thread guide 12 in the same system as the needles A to E, ie loops are formed. Since the thread guide 12 is not used here until the needle F is knitted, ie not already on the needle E as in the previous exemplary embodiment, an opening is created in the knitted fabric here. For example, buttonholes, cutouts or necklines can be made.

In the Fig. 4 a further process variant is shown schematically. With a knitting system, area A is knitted with two thread guides, clad, with a monofilament thread (base thread) being knitted in front and a pattern thread being knitted afterwards. Between areas A and B, the trailing thread guide (pattern thread guide) is pulled back against the knitting direction so far that it no longer lays into the driven needles. The trailing thread guide runs over area B and floats. The leading thread guide (monofilament thread) inserts into the needles of area B. Between the areas B and C, the following thread guide (pattern thread guide) is accelerated again and moved into the knitting position so that the pattern thread guide is inserted again. Area C is knitted clad with both thread guides, the monofilament thread being knitted leading and the pattern thread being knitted trailing.
