Abstract
A needle selection mechanism in a hand-operated knitting machine in which collisions of parts are minimized to reduce production of noises is disclosed. The mechanism comprises a patterning data carrier mounted alongside a needle bed and a pair of needle selector units mounted on a carriage and each including first and second drums each having a set of tiltable data storing elements mounted thereon. A set of patterning data are applied from the data carrier to each selector unit to be stored thereon when the unit passes the carrier which is fed from row to row when the carriage passes it. During a movement of the carriage on the needle bed, a preceding one of the selector units effects selective actuations of movable knitting needles in accordance with the data stored thereon. The tilted data storing elements on both drums of a following one of the selector units are restored to their initial positions by a clearing member common to both drums which operates in time before the following unit reaches the data carrier.
