Abstract

Precise alignment of circular slitter blades is obtained by this arrangement. Bottom arbor 2 and top arbor 4 have notches or steps machined in them to the desired tolerances to control the positioning of removable circular blades 6. Between each pair of blades, a removable resilient spacer 8 and washer 10 are positioned to provide a rigid structure so that each blade assumes its predetermined position. During a slitting operation, a web is passed between arbors 2 and 4. These are then brought toward one another and rotated so that blades 6 can interact to slit the web.
