ABSTRACT:
The apparatus includes two retaining elements associated with the control elements, two actuating elements associated with the retaining elements, a shaft acting on the actuating elements in order to pivot the latter and to displace them in translatory motion, and an electromagnet which can be optionally energized and deenergized.
The shaft is oscillatingly driven in accordance with the motion of the control element at the timing of the loom. The actuating element is brought into contact with, and out of contact from, the electromagnet independently of the control cycle and is displaced in the direction of the retaining element only when the electromagnet is not energized. The actuating element need therefore be displaced only once during the period of time defined by the clearance S, so that the operating speed of the loom can be increased.
