ABSTRACT:
There is disclosed herein an apparatus for forming container blanks from cardboard or other paperboard-like substrates. The apparatus includes a press, platens, a coated plate member, and a die-and-knife assembly. The coating on the plate is impressible by the back edge of the knife for accommodating irregularities in the machine, platen surface, or knife so as to permit the knife edges to substantially lie in a cutting plane. The coating is generally an organic coating which is liquid just above room temperature and solid at room temperature. The impressions are made in the coating and the coating is then hardened for use by polymerization such as by ultraviolet light.
