ABSTRACT:
A process and apparatus is disclosed for feeding weft threads to a warp knitting machine including longitudinal conveyors traveling towards the knitting instrumentalities. Weft thread rakes are arranged outside of the longitudinal conveyors and are movable between a starting position in which the weft threads are placed into the longitudinal conveyors and the rakes, and a racking position against the traveling direction of movement of the longitudinal conveyors. After reaching the racking position, the weft threads are transferred onto the longitudinal conveyors and the rakes are then returned to the starting position in the direction of travel of the longitudinal conveyors. The move of the rakes from the racking position to the starting position is effected by a temporary coupling connection of the rakes with the longitudinal conveyors. After transfer of the weft threads, this coupling connection is cancelled as the rakes reach the starting position.
