Abstract
A gripper rod for a shuttleless loom has a toothed rack section made of fiber reinforced synthetic composite, preferably thermoplastic, material. The toothed rack is made of a stack of belts of such material with rectangular perforations increasing in size from the inside out or from the bottom up. By compressing and simultaneously heating the stack the matrix material is cured, whereby the belts are bonded to one another. The gaps between the teeth may extend entirely through the rod or the rod may have a base also made of such belts but not having any perforations.
Claims7
A gripper rod for a shuttleless loom, comprising a toothed rack section for cooperation with a pinion for driving said gripper rod, said gripper rod comprising a plurality of fiber reinforced belts of synthetic material laminated and bonded to one another to form a stack of said fiber reinforced belts, said belts further comprising perforations with dimensions increasing from belt to belt in an outward direction, and lands with correspondingly decreasing dimensions from belt to belt in said outward direction, said belts being arranged relative to each other so that said perforations are arranged in alignment relative to a central perforation axis extending perpendicularly to planes defined by said perforations in said belts so that teeth are formed by said lands between adjacent perforations for meshing with said pinion.
