Heald control mechanism

摘要

A heald control mechanism including at least one elongate heald rod movable longitudinally between first and second limits of reciprocal motion; a heald rod motive means continuously reciprocating along a path parallel to the longitudinal axis of the heald rod; the heald rod being biased to normally reside at the first limit of reciprocal motion; the heald rod and motive means including co-operating latch means which automatically engage when the motive means moves relative to the heald rod along said path in a direction toward the second limit of reciprocal motion and which automatically disengage when the motive means moves relative to the heald rod along said path in the opposite direction; and heald rod selection control means operable to selectively isolate the co-operating latch means when the heald rod resides at said first limit of reciprocal motion and which on actuation renders active the co-operating latch means to enable the motive means to move the heald rod toward said second limit of reciprocal motion. <IMAGE>
