Warp knitting machine with thread insert

The innovation concerns a warp knitting machine that works with reciprocating and thread inserts are used as a comb for inserting long weft threads is.

When inserting long weft threads with a long weft device, in particular but with magazine firing devices, the threads are often depending on the thread material, Thread tension or due to other influences in vibrations of different amplitudes, so that they, at least in the area of largest oscillation amplitude, not covered by the moving thread inserts and thereby cause errors.

Attempts have been made to avoid this deficiency by arranging a comb, which for this purpose is pivotably mounted on the Gel.ängewelle and driven by additional control means arranged on the guide rail hanger in such a way that in addition to his usual back and forth movement, he also moves up and down

runs to bring the weft threads to the loop formation point. However, this arrangement is associated with considerable effort and expense additional space is required for the control means outside of the lay-on hangers.

With the innovation, however, a well-known thread insert is used, the only performs its usual to-and-fro movement and the, as well known, also serves as a comb to hold down the forming goods.

Nsiisrungsgeinäß is above this thread insert ir! Needle stroke direction fixed

at the Genänyewcllc 6ΊΠ6Γ ΒοΓΡβ änycGPdnst, which 5Π some StsllSfl distributed over the length of the bar, has thread guide surfaces extending backwards and pressing the fed weft threads into the thread inserters. These novel guide surfaces, which are simple in their design and arrangement, only serve to reliably feed the weft thread of the magazine device to the thread inserts, which then bring it to the loop formation point as before.

In an expedient further development of the innovation, it is provided that the thread guide surfaces are arranged on the rearward-facing leg attached to the front of the bars, brackets or the like, and beyond have a slightly upward portion.

Below is an exemplary embodiment of the innovation based on the drawing explained. Show it:

the same representation in different working positions.

A basic knitted fabric is worked with the two guide rails 1 of the Raschel machine, one after the other or after a certain pattern at intervals Weft threads 2 in the present example by means of a Magazmschußeinrich = tion can be supplied. The weft threads are brought into the loop formation point by the reciprocating thread inserter 3 and the sections 4 and 5 of the guide surfaces 6 on the bracket 7, which is fastened to the bar 8, cause the weft thread 2 to get safely into the thread insert 3 and off this is detected, as can be seen from the further working positions of the knitting tools in FIGS.

Claims (3)

PROTECTION CLAIM: 1. Warp knitting machine with reciprocating, and as a cutting comb serving thread inserts for inserting long weft threads is equipped, characterized in that above the Thread inserter (3) firmly on the hanger shaft in the needle stroke direction Bar (8) is arranged, which is distributed at some points over the length of the bar, tightly rearward extending, the fed weft threads (2) into the thread inserter (3) pressing thread guide surfaces (6) having. 2. Warp knitting machine according to claim 1, characterized in that the thread guide surfaces (6) on the rearwardly directed legs at the front of the bar (8) attached brackets (7), angles or the like are arranged. 3. Warp knitting machine according to claim 1 or 2, characterized in that guide surfaces (6) have a slightly upwardly directed Section (4) have.
