ABSTRACT:
A pair of arms is hingedly connected to a rocker. These arms support the pressing bar. At their opposite ends the arms are pivotably mounted such to the casing of the appratus that in one position thereof the axis of rotation of the lower feeding roller coincides with the pivot axis of the pivotal point of the arms at the casing. By this design it is no longer necessary to adjust the apparatus for the intermittent feeding of a web-shaped workpiece by utilizing auxiliary structures to various respective thicknesses of the web being fed.
