ABSTRACT:
A locking lever is articulated to a latch. The locking lever is pivoted or swung out against the action of a spring and the pivoting or swinging movement is limited by a stop mounted at an eccentric. The opposite pivoting or swinging movement of the locking lever is limited by a surface at the locking lever which runs-up against a surface at the latch. Upon rotation of a drive shaft carrying the eccentric the latch can now assume a decoupling or decoupled position. Due to the provision of control levers with hook-shaped ends which, when pivoted into a predetermined position, cause the locking lever to run-up or travel against one of the hook-shaped ends, the latch is only then caused to be decoupled when subsequently and in accordance with the weaving program a decoupling operation of the latch is really intended to take place. Otherwise the latch is not decoupled because in that case the locking lever cannot run-up against one of the hook-shaped ends of the control levers.
