Abstract (en)

[origin: US4406038A] A stretch head for a stretching mechanism includes a plurality of needle rods which move along a generally planar working path and a return path. Linear motor means are operable to move the needle rods along the planar working path along material to be warped and along the return path, and screw means move the needle rods between the two paths.
