APPARATUS AND METHOD FOR FORMING A BENDING CREASE IN CORRUGATED PAPERBOARD

摘要

An apparatus for forming a bending crease in corrugated paperboard includes a circumferential portion of a wheel. The circumferential portion has a width and a peripheral surface positioned to compressively rollably receive a corrugated paperboard between the surface of the wheel and a support surface. The circumferential portion includes a protrusion extending radially outward from the circumferential portion greater than 0.070 inch. The protrusion extends radially outward from a base to a tip opposite the peripheral surface, the tip having a width less than the width of the base. The protrusion is configured to form a crease in the corrugated paperboard, the crease having sufficient depth and a width less than or equal to the width of the base, thereby resulting in a bend line formed in the corrugated paperboard that is substantially coincident with the formed crease.

1. An apparatus for forming a bending crease in corrugated paperboard comprising:
a circumferential portion of a wheel, the circumferential portion having a width and a peripheral surface positioned to compressively rollably receive a corrugated paperboard between the surface of the wheel and a support surface, the circumferential portion including a protrusion extending radially outward from the circumferential portion greater than 0.070 inch, the protrusion extending radially outward from a base to a tip opposite the peripheral surface, the tip having a width less than the width of the base; wherein the protrusion is configured to form a crease in the corrugated paperboard, the crease having sufficient depth and a width less than or equal to the width of the base, thereby resulting in a bend line formed in the corrugated paperboard that is substantially coincident with the formed crease.
