Embodiment Construction

[0078] With reference to the above-mentioned figures, the jacquard device 1 according to the invention for selectively moving thread guides 2 in a knitting machine comprises at least one support element 3 provided with a plurality of housings 4 for a plurality of thread guides 2 .

[0079] Preferably, the support element 3 comprises an upper part 3a ( Figure 5 ) (further divided into other sub-parts), at least one middle part 3b and lower part 3c ( Image 6 with 6 A).

[0080]In the preferred embodiment described here, the support element 3 is a jacquard-type thread guide rod for a linear warp knitting machine and is movable relative to at least one needle bed 5 of knitting needles 6 (according to the prior art, at least with the usual Swing (SWING) and needle bed traverse (SHOG) motion) for selectively feeding yarn 7 to the knitting needles of said needle bed.

[0081] The machine in which the embodiment is described here (not shown as a whole since it is of a known type...

Abstract

A jacquard device (1) for selectively shifting thread-guides (2) in a knitting machine, comprising at least one supporting element (3) provided with a plurality of housing seats (4) for a plurality of thread-guides (2), a plurality of thread-guides (2) mounted onto the supporting element (3) and having at least one thread-guide portion (2b) selectively moving at least between a first and a secondoperating position and apt to guide a thread (7), at least one actuating element (12) for each thread-guide (2) for shifting the thread-guide portions (2b) of the thread-guides (2) between the first operating position and the second operating position, and at least one electropneumatic actuating device (15) operatively connected to the actuating element (12) for shifting the thread-guide portion (2b) of the thread-guides (2).

Description

technical field [0001] The present invention relates to a jacquard device for selectively moving yarn guides in a knitting machine, in particular for linear knitting machines, such as raschel and similar types of warp knitting machines, to obtain e.g. jacquard fabrics etc. Various knitted fabrics. Background technique [0002] As is known, modern Jacquard looms are provided with and feature means adapted to selectively move the yarn guides according to the pattern desired to be obtained in the fabric. [0003] For this purpose, basically two technologies are now used: one makes use of piezoelectric or piezo-ceramic elements, and the other uses a much older system, still as efficient as the first, for pulling and pushing the displacement element, Said displacement elements are able to deflect the thread guides at their lower ends. According to known technology, in this region the thread guide holes of the thread feeder through which the knitting yarn passes should interact ...
