PCT No. PCT/SE93/00497 Sec. 371 Date Dec. 5, 1994 Sec. 102(e) Date Dec. 5, 1994 PCT Filed Jun. 4, 1993 PCT Pub. No. WO93/25740 PCT Pub. Date Dec. 23, 1993In a weaving machine a control unit for controlling the movement of the shaft frames or harnesses creates a feedback function through load cells and AC-servo motors that enables accurate shaft frame adjustment in forming an open shed. The weaving machine includes detecting mechanisms that detect parameters regarding condition the shaft frames. An individual control unit controls each of the shaft frames. The control units adjust the shaft frames in one or more positions to create open and closed sheds in the warp threads to enable the weft threads to be inserted by the shuttles as the warp threads change position. The control units receive feedback data of at least one of the parameters from the detecting mechanisms, such that operation of the control units incorporates the feedback data. Control systems control the control units to create a substantially constant level in the butting edge of the fabric irrespective of the positions of the shaft frames. |
