ABSTRACT:
This invention relates to a warp knitting machine which is equipped with two longitudinal conveyors for conveying weft yarn groups towards a knitting head. The longitudinal conveyors comprise a plurality of hooks for engaging and holding the weft yarns and a weft yarn carriage is provided for laying the groups of weft yarns from one conveyor to the other. Each of the conveyors are provided with a depressing mechanism which includes a depressor which has an inactive position, an intermediate position and a depressing position. Means are provided for moving the depressor from the inactive position to an immediate position extending over a group of weft yarns laid between the hooks on one of the conveyors. Another means is provided for lowering the depressor from the intermediate position to the depressing position to depress the group of yarns into the hooks of the conveyor and for holding them there until the weft yarns are securely engaged in the hooks.
