Abstract
A device for coupling and uncoupling heald shafts (1) to shaft rods (2) in a loom comprises first and second coupling portions (6, 7) attached to shafts (1) and shaft rods (2), respectively, and a latch member (8) for latching the coupling portions to each other. A pivotable actuating member (14) is pivotably coupled to the shaft drive to move the coupling portions between a rest position, where the shaft rods are uncoupled to the shafts, and a working position, where the shaft rods are coupled to the shafts for operation of the device. A support member (15) is coupled to the shaft drive and comprises a plurality of elongate holes (17) for receiving and guiding the shaft rods during operation of the loom and V-shaped notches (19) aligned with each of the elongate holes to secure the shaft rods in a stable position when the rods are uncoupled to the shafts. The shaft rods are designed so that the ratio of the length of each rod to the maximum stroke height, i.e., the axial distance in which the shaft drive reciprocates the shaft rods, creates a free space underneath the shafts for permanently guiding the shaft rods into the support member.
