Abstract
The actuating tool for coupling and uncoupling the coupling elements of the shaft coupling arrangement is rotatably mounted in the loom frame externally of the coupling elements. The tool includes a drive shaft, crank webs which extend transversely of the drive shaft and a pair of rollers which are disposed externally of the coupling elements. Upon pivoting of the tool, the rollers effect coupling or uncoupling of the coupling elements. The tool may be operated automatically and may be constructed so as to guide the individual push rods of the shaft drive when loom shafts are not present.
