ABSTRACT:
A roller is rotatably supported by a roller holder which in turn is supported by a mounting frame so as to be adjustably displaceable downwardly relative to the latter when pressed by an adjusting screw. The adjusting screw includes a flange fixedly mounted thereon just below its slotted head, and the mounting frame has stop means engageable with the flange on the adjusting screw to restrain the latter from movement in its loosening direction.
