Abstract: An apparatus for capturing and stabilizing yarn prior to interweaving thereof. The apparatus is comprised of a generally tubular body having an open end, an open side and a generally vertical slot which extends between the open side and the open end.

Abstract: A split heddle for controlling a yarn is particularly useful in automated seaming machines. The heddle is comprised of two blade like members. Each member has an aperture which is intersected on one side by a slot and on the other side by a groove. The members are superimposed with the apertures in alignment and the grooves opposite the slots. The unit is secured by laser, spot or sonic welding. After insertion of the yarn(s) in the aperture, the heddle is rotated 180.degree. with respect to the yarn(s) and the yarn(s) is/are captured in the channel formed by the opposed grooves.

Abstract: An apparatus for use in seaming flat woven fabrics is disclosed. The apparatus utilizes a shed formation means to unweave yarns from a yarn fringe and presents them for interweaving in the seam area.

Abstract: A machine for forming a seam in a length of woven fabric to join together opposite ends of the gavric to thereby form an endless woven fabric belt.

Abstract: A drive unit for adjustable beds, such as hospital beds and the like, of the type which have movable head and foot sections, and/or other adjustment functions, comprises a single, unidirectional, rotary motor, and a drive shaft for each adjustable bed function. A pair of drive wheels are rotatably mounted on each of the drive shafts, and are rotated thereon in opposite directions by the motor. A pair of spring clutches are operably associated with each pair of drive wheels, and alternatively engage or connect selected drive wheels with their associated shafts to rotate the shafts, and thereby adjust the position and/or configuration of the bed.
