Abstract:
1. A device for controlling the transverse movement of the warp threads of a textile weaving machine, in particular of a textile weaving machine having individual heddle movement, with a multiplicity of driving parts for warp threads, which serve for driving the warp threads and which in each case comprise a spring drive spring means and holding means, the holding force of the holding means being opposite to the drive force of the spring drive and being capable of holding the driving parts in an upper shed position and in a lower shed position counter to the spring force, the driving parts, further, being operatively connected via force transmission elements in each case to an electric motor as a result of the activation of which a shed control by the driving parts can be initiated, and the action of the holding means being capable of being overcome by the sum of the forces of the spring drive and of the electric motor, characterized in that the driving parts are operatively connected in each case to an electric motor in a staggered or register-like manner via force transmission elements of different length, and in that the electric motors have, as compared with the driving parts, a step-up such that a movement of the electric motors causes a greater movement in the driving parts.
