Patent ID: 7111534

Claim:
A method of cutting corrugated board passing between a rotary cutting die and an anvil, stripping one or more cut scrap pieces from a scrap cutting blade, and directing the cut scrap from the cutting die and anvil, comprising; (a) directing a sheet of corrugated board through a nip area defined between the cutting die and anvil; (b) cutting one or more scrap pieces from the corrugated board as it passes through the nip; (c) utilizing a scrap stripper having a base and a flexible, angled finger to strip the cut scrap piece from the scrap blade and to control the direction of movement of the scrap piece as the scrap piece exits the nip, and wherein the flexible finger is integral with the base and extends outwardly over the base at an acute angle with respect to the base such that an opening is defined between the angled finger and the base; (d) compressing the scrap stripper between the cutting die and the scrap piece by bending and compressing the finger against the base, closing the opening existing between the angled finger and the base, and compressing both the finger and bass as the scrap stripper moves through the nip; (e) expanding the scrap stripper as the scrap stripper moves from the nip and engaging the cut scrap piece and stripping the cut scrap piece from the scrap cutting blade; and (f) extending the flexible finger outwardly as the scrap stripper moves from the nip and engaging the cut scrap piece with the extended finger and holding the cut scrap piece against the anvil with the finger such that the anvil tends to direct the cut scrap piece away from the nip and away from the cutting die and anvil.
