SELECTION DEVICE FOR THE NEEDLES OF A KNITTING MACHINE ABSTRACT OF THE DISCLOSURE A selection device for knitting machines having a rotating cylinder with slots around its circumference for accommodating a knitting needle and an associated knitting jack in each slot, the device including a selection tape loop for controlling the jack selectors of the knitting machine. The jack selectors are movable between an operative jack position and a non-operative jack position. Stationary detecting elements co-act with the tape loop for determining the positions of the jack selectors to provide a predetermined knitting pattern. A drive mechanism moves the tape loop in synchronization with the cylinder and relative to the stationary detecting element. Cam elements are provided for moving each of the needle jacks in the operative jack position along its slot into engagement with its associated knitting needle to move the associated knitting needle into an active position for knitting the desired pattern, whereby the needles associated with each of the needle jacks in the non-operative jack position remain in their respective slots and are non- operative during knitting. Control holes are also provided in the tape loop for coacting with a disengagement mechanism for stopping the drive mechanism at a predetermined time. 1.
