A trick location detector is provided on the carriage for detecting varying positions, expressed in terms of the number of tricks from one or the other tricked end of a needle bed, of the carriage on the needle bed during its run thereon. Coupling plungers in a plunger box on the carriage are controlled by solenoids in such a way that the plungers each is actuated to slide to its operative position relative to one of the yarn carriers for engagement therewith so that the yarn carrier so engaged by the plunger is carried along by the carriage over the predetermined distance.

Abstract: A thread control device of a weft knitting machine comprises a thread guide, which is fastened to a weft rod. The weft rod is mounted to be pivotable about its longitudinal axis and to be axially displaceable in supports, which in turn are movable at right angles to the axis. The weft rod is connected to be secure against rotation with a non-axially displaceable crank. A non-rotatable drive transfer member is reciprocatingly displaceable in a plane parallel to the axis by, for example, a pivot arm. A thrust member is articulated by ball joints to the crank and to the transfer member and in operation converts reciprocating motion of the transfer member into oscillatory pivotation of the crank. Such a thread control device makes high operating speeds possible and enables production of tapes with complicated patterns.
