Problems solved by technology

However, this solution has the disadvantage that, due to manufacturing tolerances, the radially inner and radially outer surfaces of the grooves cannot be economically produced so accurately that they can be formed within the range of rotation of the jacquard disk Set the curve roller inside, relative to the jacquard disc, uniform gap or uniform prestress

Embodiment Construction

[0023] according to figure 1 The bar device has a bar 2 which can also be called a thread guide bar. A plurality of thread guides 3 are secured to the bar 2 , for example in the form of eyelets or guide needles.

[0024] During operation, the bars are driven back and forth as indicated by the double arrow 4 . The double arrow 4 shows a direction parallel to the longitudinal extension of the bar. In many cases, the bar 2 also moves perpendicularly to the plane of the drawing during the loop forming process. However, this is not explained further in the current run.

[0025] The comb device 1 has a traverse drive device. The traversing drive has a jacquard element 5 in the form of a jacquard disc with a first peripheral surface 6 . Said jacquard elements 5 are rotated by a drive motor 7 . It is also possible to use a jacquard chain instead of a jacquard disc.

[0026] The jacquard tappet 8 bears against the first peripheral surface 6 of the jacquard element 5 with a rolle...

Abstract

The invention discloses a guide bar arrangement (1) of a warp knitting machine which has at least one guide bar (2), transverse moving devices (5-7) acting on the guide bar (2) in an exclusive drive direction and a pull back arrangement acting opposite to the drive direction. It is wanted to agree a high working speed with a high accuracy. For this purpose, the pull back arrangement has pull back drive devices (11-17).

Description

technical field [0001] The invention relates to a bar arrangement of a warp knitting machine with at least one bar, a traverse drive acting on the bar in a single drive direction and acting counter to the drive direction pullback device. Background technique [0002] In order to manufacture knitted fabrics, loops must be formed. In order to form a loop, the warp thread must then be made to surround the knitting needles by means of yarn guide needles, also known as eye needles, or other yarn guides. The guide needles are here arranged on the bar. The guide needles arranged at the bar must all move in the same way. The movement of the guide needle in the direction of its longitudinal extension is brought about by a so-called traversing drive. The traversing drive can have, for example, a jacquard disc or a jacquard chain against which a jacquard tappet operatively connected to the bar bears. The jacquard tappets are held on the jacquard disc or the jacquard chain by a pul...
