ABSTRACT:
A shed forming device positions warp yarns in order to form a shed in accordance with a pattern to be woven, before inserting a weft through this shed. The positioning of the warp yarns is one potential cause of an increase or a decrease of potential energy in the shed forming device. One or several elements is added to compensate, by their change of state, partly or entirely for the decrease or increase of potential energy which is produced in the shed forming device by the positioning of the warp yarns. The change of state of the elements is effectuated without any coupling with the positioning of individual warn yarns. A weaving machine uses such a shed forming device.
