ABSTRACT:
An apparatus for slitting a web material to a desired width comprises a pair of movable frames each holding a pair of coacting upper and lower slitting edges, and a plurality of rotatable spacer rollers which are positionable selectively between the left and right slitting edges so as to support the web material being slit. The movable frames can be symmetrically moved toward and away from each other so as to adjust the distance between the left and right slitting edges to a desired width to which the web material is to be slit. In accordance with the adjusted distance, the rotatable spacer rollers can be posititioned selectively between the slitting edges, thereby supporting the web material over substantially its entire width.
