Patent

CA 2156201

A cutter and transport roller of the type described that is used for webs of materials is particularly well suited as a counter-roller in a machine for winding on continuously supplied webs of film, paper, or similar material. A separating body is installed within the internal space of the roller and together with the periphery of the roller this defines at least one pressure chamber that is connected to the environment through continuous bores in the roller casing and extends essentially across the total axial length of the war. Outside the area of the continuous bores, the periphery of the roller also incorporates a slot that, in its turn, extends essentially across the total axial length of the roller and accommodates a separator blade that is supported within the interiors space of the roller.
