ABSTRACT:
A fabric rolling unit comprises a pair of tangential fabric-rolling rollers, one of which is a driving roller and the other one is a driven roller, with the axes of said rollers being parallel to each other and horizontal, on which rollers either a beam tangentially rests, on which the fabric roll is wound, or the same fabric roll respectively rests. In order to make it possible for large-diameter fabric rolls to be obtained, the beam is supported in a freely revolving way at the upper ends of the stems of two vertical hydraulic cylinders. Inside the upper chamber of these cylinders a constant pressure is preset, whereas inside the lower chamber of said cylinders the pressure is controlled and varied by means of proportional valve. The proportional valve, in turn, is controlled via an electronic circuit, by a load cell which constantly monitors the variable load applied by the beam and by the fabric roll during the rolling process, so as to keep constant the load applied to the cell.
