<p>This patent publication discloses a method and assembly for severing a perforated continuous form along two lines. According to the invention the paper web is clamped by three clamping elements (6, 11, 15) extending essentially orthogonal over the entire width of the paper web (41 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 said clamping elements (6, 11, 15) and the clamped paper web is tensioned by actuating severing elements (5, 16) placed between said clamping elements (6, 11, 15) to enter anvil grooves (12, 17) made in the anvil plate in order to severe the paper web at the perforation (5) by increased tensional stress. The apparatus implemented according to the invention provides a fast and reliable function .</p> |
