Abstract

A cam system for flat-bed knitting machines has a needle cam unit which has at least one integrated knitting cam loop transferring cam for both knitting and loop transferring directions, of which the knitting cam has adjustable sinker elements on both sides and the loop transferring cam has transfer cam parts with a central lobe, located above the knitting track, for transferring the loops and receiving cam parts associated with them having a central receiving lobe and an oblique face that is operative in a trailing fashion. The cam system also has a depressor apparatus, in which the needles supported in needle tracks of the needle beds are controlled by pressure jacks acting upon needle jacks, the pressure feet of the pressure jacks being movable into different tracks, which are located in the planes of pressure strips. Other than the already present and movable sinker elements for sinking movements, this cam system has no further moving parts nor additional width, is intended to enable more-advantageous and more-reliable loop transfer by proving that lobes for pre-tensing the loops are provided for the transfer cam parts, and the receiving cam parts permit a substantially later r…
