  • Patent number: 3990269
    Abstract: Knitting needle especially for circular knitting machines, having a shock-absorbing shank. The knitting needle is torsionally twisted through a certain angle in the region of its butt. The torsional twist, on the one hand, takes up the clearance in the needle trick of the needle carrier, and on the other hand, permits springing of the needle in the region of the butt, by its impact on the raising or sinker cam of a cam box system, which leads to damping the impact force. This springing of the needle also diminishes the angle of the twist, thus enabling the effecting of a line contact of a corresponding part of the butt with the cam edge. The friction between twisted needle stem or shank and its trick prevents the throwing off of the needle, thus reducing the stress to which the needles and the cam edges are exposed. The reduction of the impact force also reduces still other forces which affect the needle in the needle trick.

  • Patent number: 3949572
    Abstract: A shockless needle for circular knitting machines, wherein the needle is slidably mounted in a trick and is provided with a butt which periodically engages a needle-sliding cam. The butt extends radially from the needle in a direction at least substantially at right angles to the longitudinal axis of the needle. The needle or jack of the invention is provided at the location of the butt with a relief in order to decrease the thickness and thus the stiffness of the needle and also simultaneously increase the clearance between the butt portion and the confronting thick walls. In another embodiment, the walls of the trick of the knitting machine at the location confronting the needle butt are recessed in order to increase the clearance between the butt portion and trick walls and to provide space for the sidewise deflection of the needle when the needle is momentarily bent when its butt is engaged by the needle-sliding cam.

  • Patent number: 3943732
    Abstract: A shockless needle for circular knitting machines wherein the needle is slidably mounted in a trick, and is provided with a butt which periodically engages a needle-sliding cam. The butt extends laterally from the needle in a direction at least substantially at right angles to the longitudinal axis of the needle, the needle being pre-sprung in the location of the butt so that the opposite sides of the needle at such location engage the corresponding confronting sides of the trick.
