Description

The invention relates to a method for producing a knitted piece on a flat knitting machine with at least one first needle bed, in which needles are driven expelled by at least one knitting system, at least one independently driven first yarn guide and at least a first knitting system, wherein the thread guide and the or Knitting systems are movable parallel to the longitudinal direction of the needle bed. The direction of movement of a knitting system corresponds to the knitting direction.

Flat knitting machines with self-propelled 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 exactly stopped and positioned at any area (point) of a row of knitting. In particular, independently driven thread guides are independent of a knitting system and independently drivable and movable.

From the EP 1 724 385 A1 a method for the production of intarsia knitting is known, wherein a yarn guide to be brought after termination of his knitting area and a system change in his color field back to an inoperative position. This prevents it from hindering the yarn guide which forms the subsequent color field, or from the yarn supplied by it being picked up by needles driven out in the following system.

So far flat knitting machines are used with self-propelled yarn guides mainly for the production of intarsia knitting, in which the limits of the color fields are maintained to the exact mesh. Ways to use flat knitting machines with self-propelled yarn guides for other complicated knitted fabrics, have not been shown.

Object of the present invention is to remedy this situation.

This object is achieved according to the invention by a method for producing a knitted piece on a flat knitting machine having the features of claim 1.

The first and the second knitting system each comprise a lock, which is driven by a carriage. The first and second knitting cam can be arranged on the same carriage and thus be moved by the same carriage. By means of the method according to the invention, it is also possible to plate by means of self-propelled thread guides, to produce split stitches and to produce a filigree knit. In this case, a yarn guide movement takes place at a time in which no stitch formation takes place.

Preferably, the thread guides are also movable perpendicular to the longitudinal direction of the needle bed.

In particular, when cladding with the method of the invention, certain areas in a knit can be reinforced or stabilized. It may be thread of a different color, structure or other material, such as a melted thread or a elastic thread, plated in predetermined areas. The yarn guide positions to each other are always individually and independently of the knitting system adjustable. This makes it possible to set which thread should be at the top or bottom. Furthermore, several needles are plated side by side. It can be exchanged alternately upper and lower thread with each needle. No special plating yarn guide is required. During step b. The knitting systems can be moved.

If split meshes are produced with the method according to the invention, openings can be produced in the fabric, for. B. to carry out other yarns. Furthermore, a knit widening can be performed on the fabric edge. For this purpose, a thread take-up can take place via two or more needles of the opposite needle bed. Furthermore, filigree or devore knitting patterns can be produced with the method according to the invention without the need for preparatory conversion measures on one or more knitting systems. Combinations with inlaid, structured, jacquard or other bindings are possible.

In step b. a self-powered second yarn guide is moved between the first and second knitting systems. This makes it possible in step c. either with two threads, namely a thread from to knit first thread guide and a thread from the second thread guide and thus to plate or to knit with a thread of a thread guide and to fleece the thread of the other thread guide.

Furthermore, it can be provided that the first and / or second yarn guide is seen in the knitting direction moves behind the needles, in which the continuation of the knitting yarn is to be inserted. This ensures a reliable thread feed.

In principle, it is conceivable in step c. just insert thread into the needles, but do not knit off any stitches. On the other hand it is conceivable, in step c. also to form stitches. This is particularly advantageous if cladding is to be performed.

After the step c. the first and the second yarn guide are moved between the second and a third knitting system, in particular when the needles are not driven out. Thereby, knitting in the third knitting system is prepared, whereby stitches of the basic knit can be formed by the third knitting system. In this case, the first and / or the second yarn guide can be moved counter to the knitting direction. In particular: the first and the second yarn guide can be seen in the knitting direction behind the last one in step c. formed mesh to be moved.

Further advantages arise when in step c. a thread guide runs after the other thread guide. This makes it possible to produce a filigree knit.

As already mentioned, stitches of the basic knit can be formed when stitches are formed with the first and / or second yarn guide and the third knitting system by expelling needles by the third knitting system and inserting yarn into the driven-out needles, the third knitting system in FIG Knitting direction is moved.

Further features and advantages of the invention will become apparent from the following detailed description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The features shown there are shown such that the features of the invention can be made clearly visible. The different features can be implemented individually for themselves or for several in any combinations in variants of the invention.

Hereinafter, the front needle bed is marked with V, the back needle bed with H, the needles of the front needle bed with capital letters, and the needles of the rear needle bed with lower case letters.

According to the Fig. 1a are formed on the needles A to F of the front needle bed V by means of a first self-propelled yarn guide and a first knitting system with a thread 1, which is guided by the first yarn guide stitches. The knitting direction is to the right. With the needles A to F a basic knitting is formed. The first thread guide is placed over the needle g of the rear needle bed H. A second self-propelled yarn guide was introduced by standard knitting techniques in the knitting process (here in the direction of knitting to the right) and is placed over the needle h of the rear needle bed H. In particular, the second thread guide is independently fluffed before the first knitting system in the area of the needle H. The guided by the second yarn guide thread is indicated by the reference numeral 2.

From the Fig. 1b It can be seen that the first and the second yarn guide are moved counter to the knitting direction to the left between the first and second knitting system and then with the second Knitting system insert their respective thread 1, 2 in the needle G of the front needle bed V, the knitting direction is again to the right. By selecting which thread guide should be leading down and trailing up, a plating offset can be set.

Subsequently, both yarn guides are floated in front of the knitting system 3 on position E self-sufficient, ie behind the needle G on which a mesh was last formed. The needles H to K are knitted in the carriage direction to the right with a third system and the thread 1 of the first thread guide (see Fig. 1c ). The knitting direction is again to the right. It is understood that the plating can also be done over several needles. Knitting the basic knit according to Fig. 1c could also be done with the thread 2 of the second thread guide. Furthermore, it would be conceivable that the second thread guide knit the needles AF and the first thread guide the needles HK.

The Fig. 2 shows an application example, wherein a first color field 5.1 were knitted with the thread of a first thread guide and a second color field 5.2 with the thread of a second thread guide. In region 5.3, the second color field 5.2 has been joined to the first color field 5.1 by forming plating meshes.

The Fig. 3 shows a further application example, wherein in each course row with the same needle a single mesh 6 was plated.

The Fig. 4 shows a further example of application, in which one or more rows of mesh 7 were alternately plated on a row. The advantage of plating with self-propelled yarn guides is that the plating is adjusted via a carriage-independent plating offset can be. The cladding can be done up or down. Functional zones can be reinforced in areas by selective thread plating. Furthermore, the knitting technique for fashionable applications, such. B. seam imitation, structure design, coloring, etc.

According to the Fig. 5a For example, in a method for producing split stitches with the thread 10 of a first thread guide and a first knitting system on the front needle bed V, a number of stitches are formed for a basic knit. The stitches are formed on the needles A to F in a knitting direction to the right. Subsequently, the first yarn guide between the first knitting system and a second knitting system to the left, that is opposite to the knitting direction, to the needle C of the front needle bed V is moved. No needles are expelled. In particular, the first self-propelled thread guide behind the needles, in which subsequently thread to be inserted, moves. Subsequently, a thread insert takes place in the needles e to f of the rear needle bed H with a second knitting system, what in Fig. 5b is shown. Of the Fig. 5b it can be seen that only thread is inserted, but no stitches are formed on the needles e, f.

Subsequently, the yarn guide is moved counter to the knitting direction between the second knitting system and a third knitting system behind the needle, with which the basic knit is to be developed. In particular, as it turns out Fig. 5c results, the yarn guide to the left to the needle D of the front needle bed V moved. Subsequently, stitching takes place on the needles G to K of the front needle bed V with the third knitting system.

The knitting process of Fig. 6a to 6c corresponds essentially to the knitting sequence according to Fig. 5a to 5c with the difference that in the Fig. 6b Thread in the needles d to g of the rear needle bed H is inserted. To make this possible, the yarn guide has been moved further to the left as in the embodiment according to Fig. 5b , The twisting of the needles F and G can be made via catch, mesh or board mesh. Also a knot in the offset to save sled strokes is possible.

The Fig. 7 shows a knitted fabric in which a split stitch 20 has been produced in the edge region over two needles.

According to the Fig. 8 a split mesh 21 was created via two needles and integrated in the mesh structure 22.

According to the Fig. 9 a split mesh 23 was created over three needles.

To use the split stitch, empty needles must be created in the area of the split stitch on the front needle bed to bring the thread loop created on the back needle bed onto the front needle bed. When creating split stitches over three or more needles, the difference with the previous knitting sequences is the length of travel of the yarn guides between the knitting systems.

The Fig. 10 shows a knitting process for the realization of a filigree knitting technique with self-propelled yarn guides. First, with a first knitting system and two self-propelled yarn guides on the needles C to G of the front needle bed V, a number of stitches are formed with the yarn 30 of the first and the yarn 31 of the second yarn guide. The knitting direction is to the right.

Subsequently, a retraction of both yarn guides against the knitting direction, d. H. to the left. This is done between the knitting systems, with unexposed needles. With the second knitting system and a leading yarn guide, d. H. the yarn guide, which guides the yarn 31, are then formed on the needles H to L stitches, while the second yarn guide travels at a distance, so that his thread 30 can not be detected by the needles in this area. With the second thread guide, d. H. the trailing thread guide, a floatation is therefore realized.

Subsequently, a retraction of the leading yarn guide, d. H. a movement of the leading yarn guide between the second knitting system and a third knitting system against the knitting direction. Subsequently, stitching is made on the needles M to R of the front needle bed V with both yarn guides and with the third knitting system.

In other words, on the needles C to G is clad with the first knitting system with two yarn guides, wherein a monofilament thread leading and knitting a basic thread is trailing. Subsequently, both yarn guides are withdrawn between the systems. It is then knitted with the monofilament yarn guide and the second system, with the ground yarn guide trailing between the second and third system, there is no needle selection, the thread floats. Subsequently, the monofilament yarn guide is withdrawn between systems 2 and 3. In the system 3 is plated on the needles M to R with two yarn guides, the monofilament thread leading and knitting the main thread trailing. Thus, a filigree knit can be generated in a simple manner. Lead and trailing thread guides can swap positions.
