Abstract (en)
[origin: EP0458754A1] The device (9A,7A,10a,10b,11A) for tensioning the warp yarns (T) allows for tension by operation of the tensioning members (11A,11B) to apply tension to opposite lateral ends of warp yarn sheet and can be adjusted as necessary and required in accordance with the time of weft picking and/or the time of shed closing. Thus, timed application of tension to warp yarns at the time of picking provides for smooth separation of warp yarns at the lateral ends, thereby forming a shed opening without a delay. As a result, failure in weft picking due to inadequate and improper shed opening can be prevented successfully. The decrease of diffrence of tension in the open shed and the closed shed points in the weaving cycle reduces vibration of droppers and as a consequence also fluffering and even the number of breaks of warp threads (T). <IMAGE> <IMAGE>
