Rotations of a circular knitting machine are counted and encoded into electrical signals. After a prescribed number of revolutions a programmer and program indicating disc signal a switching mechanism to shift a cam drum to the next position in the pattern. A first circuit is provided for operating the needle cylinder at a slower speed during the aforesaid shifting operation, and a second circuit is provided for running the machine at maximum and intermediate speeds during the knitting operation in response to a preselected pattern. The programmer includes two types of output signals for controlling the production of fabric according to type or size.

Control system for circular knitting machines and the like

A quick connection or clutching device is positioned between a continuously rotating drive member and a driven member which assures, upon disengagement, an accurate angular positioning of the driven member. In use the device is applied to a circular stocking machine and the like, for the actuation of the cam drum advance and stopping mechanism from the needle cylinder.
