Problems solved by technology

However, only a certain degree of physical deformation is possible during the stamping process, and materials with greater hardness cannot be processed
In addition, there is a risk of dirt deposits such as yarn fluff in the case of punching

Embodiment Construction

[0041] attached Figure 1a and 1b Two views of a first design example of a needle 10 according to the invention are shown. The needle 10 has a flat base part 20 with two side surfaces 20a, 20b that are substantially parallel to each other and connected by a connecting surface 20c, in particular extending circumferentially. The base part 20 has a longitudinal axis L. The base part 20 has a head part 21 with a hook part 21a and a tongue part 21b, and a foot part 22, via which base part the movement of the needle 10 within the textile machine can be controlled. Foot portion 22 is not fully shown in the figures. Between the head part 21 and the foot part 22 a middle part 23 is provided.

[0042] The region of the middle part 23 facing the head part 21 has a smaller thickness than the region facing the foot part 22, wherein the thickness refers to the distance between the two side walls 20a and 20b. The area facing the head part 21 is thus offset relative to the area facing the...

Abstract

The invention relates to a needle (10) or a printed circuit board (10 ') for textile machines, comprising a flat base body (20), wherein the base body (20) and the side faces (two substantially mutually parallel side surfaces (20a, 20b) 20a, 20b) connecting the connecting surface (20c) and in at least one of the side surfaces (20a) and / or the connecting surface at least one depression (30) is disposed, said recess (30) is made by an electrochemical taking down. ; Furthermore, the invention relates to a method for producing a needle (10) or board (10 ') for textile machines, comprising a flat base body (20), wherein the base body (20) comprises two substantially mutually parallel side surfaces (20a, 20b) and a the side surfaces (20a, 20b) connecting the connecting surface (20c) and in at least one of the side surfaces (20a) and / or the connecting surface at least one depression (30) is arranged, wherein the at least one recess (30) generated by an electrochemical taking down becomes.

Description

technical field [0001] The present invention relates to a needle or sinker for a textile machine and a manufacturing method thereof. Background technique [0002] Needles and sinkers are used in textile machines, especially knitting machines, especially for moving yarns, for example forming stitches or guiding or controlling knitting elements. [0003] A needle and sinker for a textile machine with a flat base part is known, wherein the base part consists of two substantially mutually parallel side surfaces and a connecting surface connecting the two side surfaces, and on at least one of the side surfaces and / or at least one recess on the connecting surface. The recess may be arranged in the form of a chamfer, bevel or depression within the surface or adjacent to an edge of the surface. In particular knitting needles, such as transfer needles, have such a recess in which a transfer spring is arranged. [0004] It is known to generate these recesses by cutting processes su...
