Abstract
A control device for a textile machine, in particular for a knitting machine having at least one yarn feeding device, with each yarn feeding device being provided with two stop-motion devices each respectively having an electrical stop-motion switch associated therewith. The stop-motion switches of the yarn feeding device are connected to a rectifier circuit such that the two stop-motion switches of the yarn feeding device are supplied with voltage half-waves of different polarity. A control unit is provided which is common to all stop-motion switches and which is capable of surpressing voltage half-waves of one polarity in order to neutralize the stop-motion switch supplied with the voltage halfwaves of said one polarity with reference to a relay which stops the mechanical drive of the textile machine.
