Sley for a magnetic shuttle

A sley for a loom, said loom including a reed assembly fixed on said sley, means for swinging said reed assembly to bite a strand of weft yarn into the shed of warp yarns, a raceway formed in the upper surface of said sley in front of said reed assembly, means for generating a magnetic force which moves along said raceway, and a shuttle with-side wings attractable by said magnetic force to fly along said raceway, said sley being fixed on said swinging means, said magnetic force-generating means being disposed under said raceway, characterized in that a slot is formed in said sley, in such a manner that the bottom portion of said shuttle and/or the top portion of said magnetic forcegenerating means can extend partially into said slot, so as to minimize the distance therebetween, thereby increasing said magnetic force and a separate recess is provided in said sley on each side of the slot in front of said reed assembly with each said slot having spaced apart protrusions which extend to a location flush with the upper surface of the sley and over which said wings slide.
