ABSTRACT:
An apparatus for applying substantially uniform tension to warp threads along a warp thread path in a weaving machine. The apparatus has a carrier element (5), a tensioner element (7) for the warp threads which is multiply supported thereon, said tensioner element being pivotal about the axis of the carrier element, and a drive apparatus (8) which is connected drivewise to the carrier element. The drive apparatus (8) consists of a motor (9) and a kinematic chain which is connected to the carrier element (5) in such a manner that the introduction of the forces into the carrier element takes place substantially symmetrically with respect to its longitudinal extent.
