Problems solved by technology

Machine knitting tools, on the other hand, must have a long service life and must not show signs of excessive wear or damage due to the introduction of acceleration forces
Replacing a defective machine weaving tool requires stopping the weaving machine and resulting in lost productivity

Embodiment Construction

[0037] figure 1 and Figure 7 A set 10 of a plurality of machine knitting tools 11 and, for example, a plurality of machine knitting needles 12 is shown, in particular a first machine knitting needle 12a, a second machine knitting needle 12b, A third machine knitting needle 12c and a fourth machine knitting needle 12d. The number of machine knitting tools 11 per set 10 can vary. Each group 10 can comprise two or more machine knitting tools 11 .

[0038] The machine knitting tools 11 or machine knitting needles 12 within the same group 10 are formed in different ways. The differences are described in more detail further below.

[0039] will refer to Figure 2 to Figure 6 The structure of the machine knitting needle 12 is explained based on the first machine knitting needle 12a.

[0040] The machine knitting needle 12 has a shaft 15 which extends in the longitudinal direction L between a front end 16 and a rear end 17 which is opposite the front end 16 . According to an e...

Abstract

The invention relates to a machine knitting tool (11) and in particular to a machine knitting needle (12) comprising a rod (15) extending in the longitudinal direction (L). The machine knitting tool (11) has a stitch forming portion (M) directly adjoining the front end (16); and a driving portion (A) directly adjoining the rear end (17). At least in the drive section (A), the bottom side ( 25 ) of the rod ( 15 ) has no notches or recesses and extends along a plane (E). In the drive section (A), the rod (15) forms at least one rib portion (30) with a rib height (h1) of at most 1.1 mm. In addition, in the driving part (A), the rod (15) forms at least one support protrusion (31) extending in the height direction (H) beyond the rib height (h1) of the at least one rib part (30) And has a raised height (h3) which has a maximum height.

Description

technical field [0001] The present invention relates to a machine knitting tool, and in particular to a machine knitting needle. The machine weaving tools are preferably designed for weaving staple yarns, such as cotton yarns. The machine knitting tool or the machine knitting needle is preferably a latch needle or a compound needle. Background technique [0002] A wide variety of machine knitting tools and machine knitting needles are known. During knitting with a knitting machine, the machine knitting needles, such as in particular latch needles, move in the longitudinal direction in the guide channel or needle channel. For this purpose, each machine knitting needle has a drive part with a butt part. The butt portions cooperate with cams of the knitting machine to position or move the machine knitting needles in the needle channels in the longitudinal direction. In the case of circular knitting machines, the needle cylinder (Strickzylinder) rotates together with the mac...
