Abstract: A pallet transport device having a securing element positioned between two longitudinal rails in projections of a non-driven pallet transport device. A shaped body is seated on an axle. When docking with a driven pallet transport device, each projection is pushed into a docking receptacle so that a lower, shaped activation surface contacts and pushes the shaped body into a specified position. The shaped body thus pivots about an axis and the pallet can be displaced as desired. When the pallet transport device is undocked, the shaped body pivots upwards and the securing surface locks the pallet in a locking direction. Thus, the pallet transport device can be locked or unlocked without external help and has a high degree of operational dependability.

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.
