SHEDDING DEVICE DESIGNED TO SELECT SHEDDING MEANS BY SUPPORT OF PIEZOELECTRIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a shedding device improved in energy saving, so designed that piezoelectric flexural elements select shedding means by support of a piezoelectric element having U-shaped clips with an arm allowed to slide on a hook borne on its free end so as to select the rise or non-rise of the hook smoothly and quickly. ;SOLUTION: This shedding device is designed to select shedding means by support of a piezoelectric element which actuates based on the hooking/ unhooking principle and contains ascending/descending auxiliary hooks 2, 2' and ascending/descending auxiliary blades 1, 1', and furthermore, so designed that piezoelectric flexural elements select the shedding means by support of another piezoelectric element having U-shaped clips 8, 8' with an arm 17 allowed to slide on a hook borne on its free end. The auxiliary hooks 2, 2' are elastically attached to flexural springs 3, 3' which, in turn, pull up a tackle 11, thereby also pull up a harness cord 12, are therefore allowed to slide vertically along grooves 16 by the action of the ascending blades 1, 1'.;COPYRIGHT: (C)1997,JPO
