ABSTRACT:
A control device for striper units in a circular knitting machine having a plurality of cam disks, the profil whereof is followed by a respective lever operating a respective thread finger by means of a Bowden cable. Each cam disk is secured to a respective toothed wheel meshing with a further toothed wheel which may be coupled with and uncoupled from, a drive shaft constantly rotating with a predetermined rotational speed. Coupling and uncoupling of the further toothed wheel is controlled by the main chain of the machine so as to selectively cause a rotation of substantially 180.degree. of a respective selected cam disk to bring the corresponding thread finger in operation and another rotation of substantially 180.degree. to bring the corresponding thread finger out of operation. Other cam disks are provided to control in the same manner corresponding thread cutting and gripping means each time an associated thread finger is controlled.
