Abstract

A control device for the needles of a knitting machine having a control element which, in accordance with a predetermined knitting pattern, selects the needles required for the knitting process. The needles or pushrods associated therewith are moved by a drive device, out of a rest position and into an operative position, wherein the control element has a surface which is divided up into electrically-conductive and nonconductive fields which correspond to the knitting pattern and are scanned consecutively during operation by a scanning element adapted to be moved transversely to the direction of feed of the fields. This scanning element provides an output signal of a first or a second type, depending on the character of the scanned fields. The drive device is moved past the needles or their associated pushrods synchronously with the scanning speed. In the presence of a signal of the first type, an electomagnetic setting element of the drive device is moved so that the path is free for a needle or pushrod which at this time is located in the region of the setting element so that it can move out of the rest position into the operative position.
