Shaft drive for loom shafts

[0032] figure 1 The heald frame 1 and the associated heald frame transmission 2 are shown. The heald frame 1 is composed of a frame with a wire heald 95, and the frame moves up and down as indicated by the arrow 3 during the work. For transmission, a connecting rod 4 is used, which is connected to two or more parts 5 and 6 of the heald frame 1 and constitutes the output device of the heald frame transmission device 2. There are toggle levers 7, 8 belonging to the connecting rod 4. The toggle lever is connected to the heald frame 1 on the one hand and directly or indirectly with the tie rod and the pressure rod 9 on the other hand. The pull rod and the pressure rod are connected to the heald frame transmission 2, which for this purpose has a pendulum rod 11 that follows the swing motion at the output end. The heald frame transmission 2 is generated from the uniform rotational movement of the input shaft 12 figure 1 The reciprocating movement indicated by the arrow 13 is indicated b
