CUTTER FOR WEB MATERIAL
Document Type and Number:
Japanese Patent JPS57156959
Kind Code:
A
Abstract:
A web severing apparatus is described which is operative between support rollers and a web wind-up roll employed in a web winding machine. The web severing apparatus consists of a retractable beam which is guided on axial ends of the support rollers. The beam has at its upper end a pivotably arranged mounting on which a web tear-off blade is screwed. The mounting further supports at a small distance away from the web tearing blade, a web holding element having a web contacting surface to clamp the web firmly on the roller when the web tear-off blade is so positioned relative to the web contacting surface that a narrow gap is formed between the web tearing edge of the blade and the web. When the web wind-up roll is then pushed out over one of the support rollers, the web is pulled against the web tear-off blade and is severed. With such web severing apparatus, the surface of the support roller opposite the blade and the web tear blade are protected from damage.
