DD160565A1 - METHOD AND DEVICE FOR PRODUCING EDGE FINISHED VINE - Google Patents

Abstract

The application of the invention is possible on Haekelgalonmaschinen and other warp knitting machines with a needle bar with assignable parallel to the needle shank displaceable Schussfadenfuehrern and each needle associated with a Wirkfadenfuehrer. With this invention, it is possible to produce a good-quality edge trim border with a two-ply head part and a pattern part and the joining of the parts in one operation. The head pieces and the pattern piece overlap in the middle by at least one needle pitch and are tied together. The head parts get their binding by horizontal or vertical supply of Wirkfaeden.

Title of the invention

Method and device for the production of edge trim border

Field of application of the invention

The invention is applicable to the production of edge trim cords on warp knitting machines, in particular crochet galloon machines with a needle bed with weft thread guide and warp thread guides for the pattern piece and the back and front head pieces and means for joining the head pieces and the pattern piece.

Characteristic of the known technical drawings

There is a Einfaßband known, consisting of two parts with different width, which are sewn together (DT-OS 1965 447) to achieve the character of a Einfaßbandes.

Since this assembly in relation to the voltage causes great difficulty in sewing together, another method for producing a binding tape on crochet galloon machines has been known (DE-AS 2429 653). This binding tape is made on a machine of two separately machined parts, such that the knitted parts are returned via pulleys to Hadelbarre and cooperated by means of warp thread. The production of this Einfaßbandes is possible on a Uadelbarre, but requires a considerable space-

"Requires and most accurate adjustment of the individual elements, which complicates the machine operation and thus very expensive to manufacture." The wild presentation of the separately worked parts in the interaction of this Einfaßbandes a quality lower appearance is achieved.

Object of the invention

The object of the invention is to produce a Kantenausschlußborte on a warp knitting machine with a Uadelbarre in one operation, to increase the productivity of the machine and to simplify their operation and to improve the appearance of the product.

Essence of the invention

The object of the invention is to develop a method and the associated device in order to produce an edge termination border with a two-ply head part and a pattern part and the joining of the parts in one operation. According to the invention, this object is achieved in that the knitting threads for the front head part and the pattern part, the weft threads in the closed Pransenbinding horizontal and for the rear head portion of the weft yarn in the closed fringe is tied vertically, the weft threads for the two-ply headboard with the weft threads for the Pattern part in the middle at least one lapping overlap and within this overlap the weft threads of the front and the rear head part and the pattern part is tied by at least one knitting thread. The vertical feed of the knitting yarns for the rear head part takes place between the weft threads for the rear head part and the weft threads for the front head part. The path of the weft thread for the rear head part is shorter than the path of the weft thread for the front head part by at least one HadeIteilung and thus becomes a

229627 3.

Connection of the two head parts in the outer wale area prevented.

The apparatus for performing this method is a warp knitting machine, in particular crochet galloon machine with a Hadelbarre with knitting yarn guides, which are associated with the ladein and differently displaceable weft yarn guide. To produce Kantenabschlußborte with two-layer headboard and a pattern part weft guides are spaced from each other for the front header and the rear header and the pattern member in Nadelaustriebsrichtung arranged. Between the trajectories of the weft thread guides for the front and rear head part knitting thread guide, which have both an offset drive and a drive transverse to Uadelbarre assigned to the tongue needles located in this area. By using the latch needles in this area, a separate binding of the rear header by feeding the knitting yarn from above is possible. The knitting thread is placed on the open tongue at the moment when the cut stitch is on the needle shaft and thus a good insertion and setting of the knitting thread is guaranteed.

To form the front header, this weft leader makes a stroke beyond that of the weft leader for the rear header to the outside. The path of the weft leader of the pattern part intersects with at least one hawl pitch with the tracks of the weft guides of the head parts. In the area of the overlap and in the area of the front part of the head projecting beyond the rear track, knitting thread guides in front of the weft thread guides are assigned to the!

Embodiment 1

An exemplary embodiment of the invention will be explained in more detail below with reference to drawings:

229627 3

The drawings show:

a schematic representation of the thread course of Kantenabschlußborte

a schematic representation of the assignment of the knitting yarn guide to the ladein and the trajectory of the weft

a schematic side view of the invention produced Kantenabschlußborte a cut in the loading plane to form the outer wale

a section in the loading plane to form the wales for the rear head and a section in loading plane to form the middle wale

The Kantenabschlußborte consists of a front header 1, a rear header 2 and a pattern part 3. The head weft thread 4 for the front head part 1 is tied in the outer wale 5 and the middle wale 6.

The head weft thread 4 * for the rear head part 2 is tied off by the wales 7 and the wale 6. To connect the sample part 3 with the head parts 1; 2, the pattern weft 8 within the overlap 9 with the head parts 1; 2 tied off by the middle wale 6.

The crochet galloon machine for making these edge trim trims has knitting yarn guides 10 for the front header 1 and pattern part 3 associated with the needles 11 * and knitting yarn guides 12 for the back header 2 associated with the reed needles 11. The arrangement of the knitting yarn guide 12 takes place between the weft yarn guides for the front and rear head part 1, 2.
