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.

Cette invention se rapporte à un ensemble rouleau presseur, conçu pour peser sur au moins un enroulement (29) d'une matière se présentant sous la forme d'un voile qui est maintenu, lors de son bobinage, dans un dispositif de bobinage. Ledit ensemble comporte un rouleau presseur comprenant une multitude de rouleaux de charge (2, 2') fixés par l'intermédiaire de bras de fixation (10) à une poutre de support (1), chacun desdits rouleaux de charge (2, 2') comportant un organe hydraulique de mise sous pression contre au moins un enroulement et un organe conçu pour écarter dudit enroulement par levage pneumatique. Ledit ensemble se caractérise en ce que lesdits organes respectifs de mise sous pression et de levage sont combinés au sein d'une unité à piston et cylindre (4) agissant dans deux directions et en ce que ces organes sont disposés à l'intérieur de chaque rouleau de charge (2, 2'). Grâce audit agencement, l'espace de montage nécessaire est minimal et il est particulièrement simple d'échanger les rouleaux de charge en détachant les bras de fixation de la poutre de support.
