A latch needle for loop-forming textile machines includes a needle shank having an upper side, a back and a sawslot extending into the needle shank from the upper side and oriented parallel to the shank. A hook is provided at an end of the needle shank. A spring element is disposed in the sawslot and has at least one end supported by the needle shank. A needle latch is supported in the sawslot for pivotal motion about an axis between a closed position in which the needle latch engages, with a frontal end thereof, the hook and a rearward position. The needle latch has a latch shank which includes an upper side and a lower side. In the rearward position the needle latch lies, with the upper side of the latch shank, on the upper side of the needle shank or is situated in the vicinity of the upper side of the needle shank. The latch shank further has an end part formed as a cam engaged by the spring element. The cam includes a component formed of a flat portion and/or a kink edge at the upper side of the latch shank. The component, cooperating with the spring element, determines and maintains the rearward position of the needle latch. The cam has an arcuate cam face adjoining the component and having, from the pivot axis of the needle latch, a radial distance which gradually decreases from the upper side of the latch shank towards its lower side.

Latch needle for loop-forming textile machines

A latch needle for a textile machine includes a needle shank having a sawslot defined in the needle shank by two facing cheeks forming part of the needle shank; a pivot pin supported by the cheeks and extending transversely to the length dimension of the needle shank; and a latch accommodated in the sawslot. The latch includes a latch shank having an upper side and an opposite lower side. There is further provided a bearing bore in the latch shank. The bearing bore is traversed by the pivot pin to provide for a pivotal movement of the latch relative to the needle shank. The bearing bore is spaced from the upper side at a first distance and from the lower side at a second distance; the first and second distances have unlike lengths.

A tool for a stitch forming machine which includes a bed and a plurality of guide grooves disposed in the bed, the tool including a shank slidably disposed in one of the guide grooves. The shank includes an end having a stitch forming device, and has a butt and at least two bends spaced from one another along a longitudinal direction of the shank. The bends are oriented toward the same side of the shank and are disposed in a region of the shank which, during sliding movement of the shank during operation of the knitting machine, remains within the guide groove.

Tool for stitch forming machines, particularly knitting machines

A latch needle for machines producing knit goods includes a needle shank having a slot, a needle head, and a latch. The needle shank has a first longitudinal plane of symmetry and the slot has a second longitudinal plane of symmetry. The latch is pivotably supported in the slot in the needle shank so as to be pivotable about a latch axis extending transversely to the second longitudinal plane of symmetry of the slot. The second longitudinal plane of symmetry intersects the first longitudinal plane of symmetry at an acute angle.

Latch needle for machines producing knit goods

A compound needle for a knitting machine has a machine shank of substantially rectangular cross section, in which a substantially U-shaped longitudinal groove open at the top is formed. A closing slider adapted to fit the cross section of the groove is guided in the groove in a longitudinally slidable manner, and the groove has at least one slit leading to the outside, which extends parallel to the longitudinal axis of the groove. In order to attain satisfactory removal of fluff or lint from the longitudinal groove, on the one hand, and to assure sufficient stability and resistance to transverse bending of the needle on the other, the longitudinal groove is closed on its top, at least partially, in the vicinity of the recess by means of a rib which also forms a guide for the slider.
