Title: Needle controlling mechanism for circular knitting machines

Abstract: An improvement in multi-feed circular knitting machines wherein the knitting needles are adapted to assume knitting and non-knitting conditions and whereas the jacks are suspended in the knitting needles in an articulated manner. The cam clyinder is provided with a needle lowering cam at each cam system. Each jack has at least one butt adapted to be engaged by the needle lowering cam when the corresponding jack has been swivelled on to the cam cylinder. The improvement comprises the construction and the manner of interaction of the butts and the needle lowering cam. The butts are arranged on the swivellable jacks and are selectively adapted to be pivoted away from the cam cylinder by means of a special pivoting device in each system when the corresponding needle is to misknit, that is in advance of the needle lowering cam of the system and are adapted to be swivelled back to their original position by special means immediately after having passed the needle lowering cam.
