<p>Rider roll arrangement, in order to weight at least one winding (29) of a material in the form of a web which is supported during winding in a winding device, having a rider roll, which comprises a multitude of weighting rollers (2, 2') mounted by means of brackets (10) to a support beam (1), with each weighting roller (2, 2') comprising a means for a hydraulic pressing against and a means for a pneumatic lifting away from at least one winding, characterized in that the means for pressing or lifting respectively are combined in one piston/cylinder unit (4) acting in two directions and are arranged in the interior of each weighting roller (2, 2'). Due to said arrangement, the building space is minimal and it is especially simple to exchange the weighting rollers by means of detaching the brackets from the support beam.</p> |
