Abstract
The needles (18, 19) of a needle set (17), which substantially agree in their geometry, have butts (28, 29) of different lengths, which have a predetermined breaking point (57, 58). The predetermined breaking points are differently embodied, so that the breaking torques of the butts (28, 29) of the needles (18, 19), which are a part of the set (17), are different. By means of this it is possible, on the one hand, to assuredly prevent damage to the knitting machine, but on the other hand to assure the dependable operation of the needles.
Claims11
A needle set (17), in particular for knitting machines,
- having at least two needles (18, 19) which are part of a knitting arrangement, each of which has a shank (22, 23), and from which a butt (28, 29) extends laterally away, wherein the needles (18, 19) have different butt heights, and wherein predetermined breaking points (57, 58) are embodied on each of the butts (28, 29) of both needles (18, 19) in such a way that the butts (28, 29) of the two needles (18, 19) differ in respect to their breaking resistance.
