A stamped knitting tool for textile machines and particularly for knitting machines is provided with a shank member and a working member. The shank member includes upper and lower edges and first and second end surfaces, and has at least one butt extending from one of the edges and a recess defined in the first end surface and laterally bounded by a web portion of the shank member on each side. The recess is divided into a guide region adjacent the first end surface and a following anchorage region at the rear, and the edges of the web portions facing recess have an irregular profile in the anchorage region. The working member has a needle head or needle hook disposed at one end and a connecting member portion disposed at the other end, with the connecting member portion being positioned in the recess of the shank member so that it is held in a form-locking manner by the web portions in the guide region and so that it is anchored to the shank member in the anchorage region. To provide the anchoring in the anchorage region at least one open space is provided in the anchorage region between the connecting member portion and the adjacent edge or edges of the shank member defining the recess, and a vibration damping material fills the open space and firmly connects the connecting member portion to the shank member.

Knitting tool for textile machines, particularly knitting machines

A latch needle for loop forming textile machines includes a steel needle shank and a nonmetallic latch. The steel needle shank has upper and lower edges, a sawslot defined in the needle shank and a needle hook at one end of the needle shank. The needle also includes an axle which extends transversely across the sawslot and contacts the needle shank. The latch is pivotally mounted on the axle and is provided with a noucat at one end. The latch is pivotal between an open and a closed position. When the latch is in the closed position, the noucat rests on the needle hook and when the latch is in the open position, the back surface of the latch contacts part of the needle shank. The nonmetallic material which the latch is composed of is a fiber reinforced thermoplastic homopolymer or copolymer plastic.

Latch needle for loop forming textile machines

A stamped knitting tool for textile machines, particularly knitting machines, including a shank having at least one butt and at least one closed or open-edged free space or opening formed in the shank and filled with a heterogeneous material firmly bonded to the needle shank. The shank edges outlining the free space or opening are given an irregular profile with which the heterogeneous material is anchored in the shank in a form-locking manner. According to a preferred embodiment, the shank has two spaced solid guide portions extending between its upper and lower edges with one of the guide portions being disposed in alignment with and below the butt, and at least one narrow web portion having a maximum height of 1.1 mm connecting the two guide portions together so that the facing edges of the guide portions and an edge of the web portion or portions defines the opening in the shank. In this embodiment, the material filling the opening and bonded to the shank in a form locking manner is a vibration damping material.
