Abstract
A blank cutting technique in a process for manufacturing containers such as paperboard cups, canisters and cartons provides a flaired edge which, in one embodiment, forms a precurl to facilitate the formation of a completed brim curl and in another embodiment, is used to provide a flaired edge on a lid flap of a carton. In the latter case, the flaired edge which is created assists in insertion of the lid flap into the carton opening and creates an improved seal. In the blank cutting technique, stock material is positioned on a die cutting bed across a stepped portion. The stock material is cut along a cutting line offset from and substantially parallel to the stepped portion and against a lower surface of the die cutting bed defined by the stepped portion during the cutting operation, whereby the flaired edge is formed.
