Abstract
Apparatus and method for separating product containing pouches from a travelling web of adhered films carried on a film support surface includes a rotary blade drum assembly having blade configurations with blade portions arranged to form the entire perimeter edge of the flange of the pouch which rotate in synchronous registration with grooves in the film support surface. In one form, at least one blade portion and associated groove portion are non-linear and other than longitudinal or transverse to the film support surface of the forming drum or travelling web of films. The blade portions may be heated and the rotary blade drum assembly may include insulating guides for the pouches.
