Title: Wave shed loom - has winding stations to give a precise weft length on weft carrier bobbins
Inventor: HABERHAUER KARL DIPL ING
IPC: D03D47/26
Filed: 1989-10-03
Abstract: The wave shed loom, with a winder system to give the weft carrier a length for the weaving width, has continuously driven winding stations moved to and fro in steps in sequence at the entry point for the weft carriers into the wave shed in a drive and control assembly. The weft carriers in a store cell are brought to the entry point shortly before the drive and control assembly stops. As it stops an empty returning weft carrier at the change wheel is passed to the store at the same time as a full carrier is passed into the wave shed. Flat steel strips, moving up and down through a recirculating cam belt together with angled strips and an eye form a guide path for the weft carrier, when in the open shed position, and move it onwards through the shed closing motion. The weft is beated in at the fabric edges by a reed carrier given a spiral movement by a central eccentric which describes an elliptical path through a lower support. The empty weft carrier is returned from the far end of the wave shed through a carrier change wheel to the change wheel at the winding side. ADVANTAGE - The appts. gives a precise length of weft yarn to be inserted into the wave shed. The formation of the wave shed is simplified, and allows for patterning. The weft is beated in by a small and exchangeable reed packet.

Title: Weaving loom appliance - enables reed staves to be moved, to open or close the warp as required
Inventor: BUESGEN WILHELM-ALEXANDER
IPC: D03D49/62
Filed: 1991-11-12
Abstract: Implements on a weaving loom, for plain or pile fabric, enable the warp to be spread, so that the yarn is concentrated in specific areas. The reed staves are mounted on guides which can be manipulated sideways, to open up, or close up sections of warp. The reed staves are pref. supported by boxes which run along the fixed guide bars. These have end connections to form a frame, held steady while the reed moves the weft to the feel of the cloth between changing warp coming from the healds at the back. The bottom bars can be moved closer to, or away from, a fixed bar by means of a miniature gearbox beneath the bar. The fixed bar has a crown gear drive and the movable bars at each side have screw thread advance and reverse. The crown gear drive is pref. provided with a drive spindle protruding downwards. The box section at the top, on the guide bar has a protrusion moving in the direction by means of a catch holding back the stave, taking it in or out of action. The guide bar sepn., may be varied by means of wedges and springs between the bars, so that pressure on the wedges drives the bars apart, opening the dents in the region required. USE - To weave a dense area, as a reinforcement, where required, or to leave an open area with only weft threads showing.
