Guide bar arrangement of warp knitting machine

Abstract

The invention provides a guide bar arrangement (1) of a warp knitting machine with a bar (2), a plurality of guide needles (3) group-wise combined into needle segments (4), and a drive mechanism (12) for generating the offset movement of the guide needles (3). For this purpose, the needle segments (4) are movably connected with the bar (2) in the displacement direction (8) and the drive mechanism (12) acts on the needle segments (4).

Description

technical field [0001] The present invention relates to a bar device of a warp knitting machine, which has a bar, a plurality of guide needles forming a fan-shaped plate in groups, and a drive mechanism for causing the guide needles to produce traverse motion. Background technique [0002] Such a bar arrangement is known, for example, from DE 44 35 562 C2. [0003] Another bar arrangement of this type is known from DE 1 857 100 U1. Here, the bar is suspended on the bar by means of ball guides, so that the bar can be moved back and forth in the traverse direction by the drive. [0004] In order to produce knitwear by means of a warp knitting machine, the yarn must be wound around the knitting needles by means of guide needles, sometimes called eyelet needles, during the knitting. For this reason, guide needle is usually fixed on the bar, and bar is moved back and forth on the traversing direction by drive mechanism. During the back and forth movement along the traversing d...

Problems solved by technology

This also leads to an increase in mass, which has an adverse effect on the working speed of the machine, since the mass of the bar must be accelerated and braked during any working stroke of the machine

Drive power thus rises excessively with respect to machine width and speed

In addition, there will be a lot of wear and tear
