发明名称 Method and apparatus for severing a paper web, particularly a perforated paper web
摘要 A method and an assembly for severing a perforated continuous form along two lines. The paper web is clamped by three clamping elements (6, 11, 15) extending essentially orthogonal over the entire width of the paper web (4) against an anvil plate (1) placed on the opposite side of the paper web so that the perforations (5) of the web remain aligned between the clamping elements (6, 11, 15) and the clamped paper web is tensioned by actuating severing elements (5, 16) placed between the clamping elements (6, 11, 15) to enter anvil grooves (12, 17) made in the anvil plate in order to sever the paper web at the perforation (5) by increased tensional stress. The apparatus provides a fast and reliable function.
