Universal knife hold assembly

Abstract

A knife holder assembly for a knife cylinder configured to make incisions in a web material, and a method for installing knife blades on the knife cylinder. The knife holder assembly includes a knife holder having a first surface adapted for mating with an outer cylindrical surface of the knife cylinder, a second surface oppositely disposed from the first surface, a sidewall extending between the first and second surfaces, and a bore having an opening in the sidewall. An anchor is received in the bore, and a feature accessible through the second surface of the holder is provided for securing the anchor within the bore. A knife blade is secured to the knife holder with the anchor. Setup time for the knife cylinder can be reduced by moving and/or replacing blades on the knife holder instead of installing, removing, and moving the knife holder on the cylinder.
