Abstract
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.
