摘要： A synchronizing device for the selection of individual knitting needles in a straight and circular knitting machine to operate according to a desired knitting pattern includes a synchronizing rail of a magnetizable material arranged on a stationary selection needle bed and cooperating with a magneto-resistive sensor arranged on a circulating knitting carriage. The sensor includes a permanent magnet whose magnetix flux is directed perpendicularly to the synchronizing rail, and four magneto-resistive webs arranged side by side in the magnetic flux and at right angles to the direction of circulation of the carriage. The webs are connected in a bridge circuit generating positive and negative analog signals which are compared in comparators with fixed threshold values to generate leading and trailing synchronizing pulses. An additional comparator is provided for detecting the direction of circulation of the carriages.

摘要： In a straight and circular knitter, a control arrangement for supplying information upon needle selection on circulation knitting carriages includes a central control station provided with a main computer storing all information for controlling the knitting machine. Each knitting carriage is equipped with a control unit including an auxiliary computer, an end stage for operating the needles and a bus control circuit. The main computer is connected to respective circulating control units via a slide contact track and contact shoes coupled to respective auxiliary computers. The microprocessors in respective control units are interconnected by a bus including a transmitting line, a receiving and a bus control line. The bus control line forms with the bus control circuits and microcomputers of respective control units a closed loop which controls the transmission of error data to the main computer in the event that an error is detected in a control unit.
