摘要:
A slitting roll for slitting an advancing sheet of elongate flexible foam material or the like to form a pattern of incisions therein. The roll includes a plurality of ribs of inverted Vshaped profile in the surface thereof, the ribs being disposed along a small helix angle with respect to the axis of the roll. A series of spaced radial apertures are formed in the ribs to define a plurality of spaced cutting blades, and the roll comprises a series of coaxial roll sections fixedly assembled onto a common supporting shaft.
