ABSTRACT:
The control system of a coupling apparatus of a dobby loom includes a hollow drive shaft, at least one eccentric hoop supported thereupon and a connecting rod arranged therearound for a controlled drive of an element. A dog is supported radially displaceable in the eccentric hoop and may be brought in a controlled manner via corresponding actuating means into engagement either into one of two recesses of the connecting rod or in one of two recesses of the drive shaft. For structural simplicity, the actuating means and the direct control means for the dog are located within the drive shaft, i.e. in the center of roation of the coupling.
