The invention pertains to a winding machine for winding a product web with two support rolls, which are mounted parallel to each other to form an intermediate space and together form a winding bed to received the wound paper roll, one of these rolls being encircled by the web coming from underneath. The machine also has a web slitting device located in the intermediate space, comprising a blade carrier with blade, which, for the purpose of slitting the web, is connected to a transverse beam so that it can be pivoted toward the web. The invention is characterized in that the blade carrier is designed as an articulated lever, one end of which carries the blade, and the other end (support end), while the blade is slitting, forms a support roller not supporting the web, with the result that the blade carrier is automatically locked in position.
La présente invention se rapporte à une bobineuse servant à enrouler un produit en bande, constituée de deux cylindres porteurs montés parallèlement l'un à l'autre, et séparés par un espace intermédiaire; la bande de papier arrive par en dessous, passe entre les deux cylindres porteurs et s'enroule partiellement sur l'un des cylindres avant d'être bobinée en rouleau. La machine comporte également un tranche-bobine positionné dans l'espace séparant les cylindres porteurs; le tranche-bobine comporte un porte-lame et une lame, laquelle est couplée à une poutrelle transversale commandant son pivotement vers la bande. La présente invention se caractérise en ce que le porte-lame constitue un levier articulé; l'une des extrémités du levier porte la lame, tandis que l'autre extrémité (qui sert au support) assure le verrouillage du porte-lame dans la position appropriée.
