Abstract (en)
[origin: EP0331634A1] The carriage (6) is moved so that the periphery of the roller (4) bears against the reel (3). The blade (14) of the cutter (5) cuts the wrapper of the reel and a few outer turns of the web. The roller (4) is set into operation such that the waste off-cuts are sucked up by the device (8) into which the free end of the web (3) is also inserted. The suction device (8) pivots downwards so that the free part of the web lies on the presentation unit (54) which has in the meantime been advanced. <IMAGE>
