The invention relates to a cutting device for a winding machine for winding a web of material, particularly a paper web, the winding machine having two support rollers, one of the support rollers being partially wrapped by the web of material which is advanced upward from underneath the support rollers and introduced into a space between the support rollers, to be wound into a finished roll which rests on the winding bed formed by the two support rollers. A tiltable cutting device includes a blade, a blade carrier, a connecting link, and a support structure. The blade carrier and the support structure are pivotally connected to each other by the connecting link in such a manner that the blade carrier can be tilted into a position in which the blade faces the web of material while the opposite end of the blade carrier rests against the outer surface of the unwrapped support roller.
L'invention se rapporte à un outil de coupe pour bobineuse de matériau en bande, notamment une bande de papier; la bobineuse est dotée de deux cylindres de support, l'un de ces cylindres de support étant partiellement enveloppé par la bande de matériau qui, entraînée par en-dessous et vers le haut, est ensuite introduite dans l'écartement entre les cylindres de support pour bobinage final par les deux cylindres de support. Un dispositif de coupe inclinable comporte une lame, un porte-lame, une biellette de connexion et une structure de support. Le porte-lame et la structure de support sont reliés par un mécanisme de pivotement, de manière telle que le porte-lame puisse être incliné dans une position dans laquelle la lame se trouve orientée vers la bande de matériau, tandis que le côté opposé du porte-lame se trouve en contact avec la surface externe le cylindre de support non enveloppé.
