ABSTRACT:
The tensioning beam assembly has a tensioning beam and/or support beam mounted in step bearings located across the width of the weaving machine. Sagging of the tensioning element is eliminated and reduced diameter tensioning elements and support beams can be used.
The tensioning element may be formed as a solid shaft which is rotatably mounted in individual step bearings on the support beam or fixedly mounted by connecting pieces to the support beam. In one embodiment, the tensioning element is in the form of a plate which is secured directly to the support beam and which has a curved outer end over which the warp threads pass. In still another embodiment, the tensioning element is in the form of a U-shaped plastic strip which is mounted about a projection extending along the support beam.
