Abstract (en)
[origin: WO2004113210A1] The invention concerns means for unrolling at least one narrow web (3) of material at a time from perforated multiple rolls (2) having webs of material consisting of preferably dryformed paper. The means include a locking disc (5) rotatably supported by a frame (4) and from the center of which a shaft (6) for carrying the relevant multiple roll (2) extends outwardly, said locking disc (5) having a plurality of apertures (7) disposed in its surface and being connected to a source (8) of vacuum over a connection (9) for causing the multiple roll (2) to adhere thereto by means of vacuum for affixing the multiple roll (2) in position during the unrolling concurrently with respective webs (3) of material included in the roll (2) being detachable along perforations (10) limiting the widths of said webs of material, and at least one mechanical support member (11) for being applied in the direction of the shaft (6) and being positioned at an adjustable predetermined distance from the locking disc (5), said distance corresponding to the width of at least one web (3) of material in the direction of the exterior (19) of one or a plurality of remaining webs of material for preventing collapse of tilting of the web (3) of material or webs of material remaining on the shaft (6) during the unrolling.
