摘要：A method and an assembly for severing a perforated continuous form alongtwo lines. The paper web is clamped by three clamping elements (6, 11, 15) extendingessentially 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 webremain aligned between the clamping elements (6, 11, 15) and the clamped paper web istensioned 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 thepaper web at the perforation (5) by increased tensional stress. The apparatus provides afast and reliable function.
