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. The pivotation can be produced and controlled by a dog chain guided over a cylinder, which can guide other dog chains for displacement of additional weft rods and the axis of which extends at right angles to the weft rods.
