Claims

The object of the invention is to improve the Nadsl in such a way that shock peaks and vibrations are prevented, or at least theirs

1. Steel latch needle for knitting machines, tension peaks are reduced,

According to the invention, this is achieved in that at least part of the needle base consists of a shock-absorbing material (4, 4 ', 12, 14) at least part of the needle base
Material. Even if such a shock-absorbing one

2. Latch needle according to claim 1, characterized in that part of the existing material is only tenths of a millimeter indicates that the needle butt (14) is made entirely of io strong, as naturally dictates the needle size shock-absorbing material exists and can, it exercises as at the place of origin of the shock, Recesses (14 ') in the needle shaft (1) are fastened at the point where the needle punched together is. ßes with the needle controls of the knitting machine,

3. Latch needle according to Claim 1, characterized in that the shock-absorbing effect is carried out and carried out indicates that the shock-absorbing 15 thus to the desired success.

Material existing part (12) slots in the needle- The needle butt can also according to the invention
