ES385350A1 - Electric pattern attachment for a multi-system circular knitting machine - Google Patents

Abstract

Improvements introduced into electrical pattern forming devices for circular knitting machines of various knitting systems with rotating needle cylinders and magnetically actuated positioning members depending on the pattern, in the various systems, members acting on the needles or on needle pushers, whose heels are staggered on the periphery of the needle cylinder; with a drawing program carrier containing information corresponding to the drawing to be knitted, with a reading device to produce drawing signals corresponding to the information contained in the drawing program carrier, and with gate circuits, bistable circuit elements, memories and amplifying steps, through which the drawing signals determine the state of excitation of the electromagnets of the positioning members synchronized with the rotary movement of the needle cylinder, characterized in that as the carrier of the drawing program A binary-coded fixed drawing memory is provided from which the information for the repetition of the drawing or for the proportion of repetition of the drawing of the different knitting systems of the machine is read by means of a reading device taking into account needle separation from one knitting system to the other, successively, for each a point formation system in the direction of rotation of the needle cylinder, under the control of an association mechanism and delivered for each rotation of the needle cylinder to a repeat memory associated with the corresponding point formation system or in the In the case of a width of repetition of drawing that in number of mesh columns is different from the number of electromagnets per point formation system, it is led to the electromagnets without storing it, through intermediate steps.
