Abstract
A pulley-less shed-forming device for a weaving machine, such as a jacquard machine, has a number of shed-forming elements ( ), such as hooks, to determine the positions of one or more warp yarns on a weaving machine. A lifting device ( ), ( ) moves the shed-forming elements ( ) up and down. At least one actuator ( )-( ), ( ), ( ) is provided for selectively influencing the shed-forming element ( ), so that it is either kept at a fixed height, or is moved by means of the lifting device ( ), ( ). The element ( ) has at least one selection body ( ), ( ), ( ) which, for said selective influencing, may be moved into first or second stable positions, as desired, by an actuator ( )-( ), ( ), ( ) forming a shed-forming element ( ) in itself. It may also be formed as a device without a pulley. Because the positions of the selection body are stable, their position may be changed by a single temporal influence by the actuator making the device energy efficient.
