Abstract

An apparatus for slitting a sheet of web material has an at least one first fixed blade member and axially displaceable at least one second blade member. The axially displaceable second blade member is biased by an elastomeric biasing member that provides a continuous and uniform contact force with a face of the second blade member. The elastomeric biasing member is restrained from axial movement by a bonded ring member.
