ABSTRACT:
Cooperating slitter blades in a slitter for high bulk traveling paper web material attain high cut point pressure and minimum slit plowing and dusting as a result of critical cooperation of the slitting edges of the blades wherein one of blade edges rotates in a plane parallel to the longitudinal axis of travel of the web, and the slitting edge of the other of the blades cooperates to a penetration or overlap extent of less than 0.030 inch at a rake angle of 0 to 10 minutes and a toe-in of 5 to 30 minutes. Where the other blade edge is of high angle type an included angle between opposite faces of the edge of 15 to 30 degrees is provided and where a low angle edge is preferred, the included angle between opposite faces of the blade is between 75 and 85 degrees.
