Device for storing pre-selected patterns for circular knitting machines having a plurality of systems

Claim 1

A peg-board for preselected patterns for multi-system cicular knitting machines having a plurality of loop-forming members, comprising in combination, a plurality of peg control members; a supporting plate; a plurality of housings mounted on said supporting plate, each housing having at least one peg control member receiving opening; said openings being arranged in said peg-board means in rows and columns; at least one magnetic-field dependent resistance mounted in each housing adjacent to each said opening; electronic circuit means operatively connecting said magneticfield-dependent resistance to said loop-forming members of said circular knitting machine, said electronic circuit means being at least partially in the form of a printed circuit; said magnetic-field-resistance includes a plurality of field plates and permanent magnetic means, each field plate forming part of a separate electronic switching circuit of said electronic means; said peg control members being adapted to be inserted into said receiving openings for influencing the magnetic transflux characteristics of the magnetic-field-dependent resistance mounted adjacent the corresponding receiving opening and thereby adjusting the actuation of at least one loop-forming member in said circular knitting machine; each said permanent magnet means having a pair of pole legs which define an air gap between the opposed ends thereof, one of said field plates being disposed in said air gap, some of said peg control members having at least one magnetically conductive member mounted thereon which serves to bridge said air gap in the opening in which said peg control member is inserted.
