Abstract
An apparatus and method for coupling and uncoupling a plurality of heald shafts (31) to and from their corresponding shaft rods (2) in a shaft drive. Male and female coupling parts (3, 5) are connected to each heald shaft and shaft rod, respectively, and a locking element 4 is pivotally mounted within the female coupling part to lock these parts together. Two drive units (7, 8) pivot two U-shaped shackles (9, 10) from an open position into a closed position. This movement unlocks each locking element so that each male coupling part and heald shaft can be vertically removed from its female coupling part. At the same time, the shackles secure each female coupling part so that they will remain in position to receive the next heald shaft.
