ABSTRACT:
The weft yarn tensioning device has a tensioning lever whose yarn-tensioning and yarn-releasing movements are controlled positively by means of two cams. An adjusting element is disposed between the cams and is provided with a cam segment adjacent a respective cam. The camming surfaces of the cam segments each form a continuation of the camming surface of an associated cam for the release movement of the tensioning lever. The cam segments can be adjusted relative to the cams so that the pattern of the release movement is adapted to the quality of the weft yarn.
