METHOD FOR CONTROLLING WARP YARN IN CONTROL DEVICE FOR WARP YARN OF PIEZOELECTRIC TYPE LOOM

摘要

PURPOSE: To miniaturize an apparatus at a high speed of response with a small power consumption without generating heat due to the accelerated action of a heald by using plural piezoelectric element groups in a warp yarn controller. ;CONSTITUTION: Plural piezoelectric elements are divided into plural block groups, which are electrically connected. The one group is electrically connected to a controller to construct a control device or piezoelectric elements of the piezoelectric element blocks are addressed to output pattern data according to the pattern procedure. The address is further advanced to successively transfer to the adjacent block groups. Similar operation is repeated until the final address is over. When a signal according to one pattern data is then completed, pulses are applied from a driver circuit of the controller to the block groups for charging before the picking is readvanced to the next stage. The pattern data according to the pattern procedure are successively outputted to advance the Jacquard weaving.;COPYRIGHT: (C)1993,JPO&Japio
