ABSTRACT:
A coupling device for connecting a heald shaft to a heald drive such as a push-pull rod and for disconnecting the heald shaft from the heald drive such as a push-pull rod has a plug-in member connected to the heald shaft and a socket member connected to the heald drive. The socket member is equipped with a toggle mechanism for locking and unlocking a pawl that engages or disengages the plug-in member. The toggle mechanism is spring loaded so that a separate locking device is not necessary. A plurality of such coupling devices are arranged in groups for operation in unison by a drive mechanism that includes a cam drive for each coupling device. All the cam drives for a group of coupling devices are secured to a splined shaft for operation in unison so that all coupling devices can be coupled or decoupled simultaneously.
