Abstract
Abstract An in-line crimping device for rigid foil containers, such as pie pans, includes a longitudinal conveyor. Oppositely disposed container drive belts are disposed along the conveyor and are engaged by the peripheral portions of the containers. The belts cooperate so that the containers rotate as they move continuously down the line. During this travel, their upwardly extending crimping flanges are engaged by one or more angularly disposed crimping members which apply radially inward angular pressure progressively to the flanges to bend the latter toward final position. This engagement by the crimping members is continuous throughout at least one complete revolution of the pan to assure full crimping action on the entire pan circumference. When a crimping member is used on only one side of the pan, means are provided to prevent flip-up of the opposite pan side. Several stages of crimping may be included in the machine, and the final crimp may be accomplished by a vertically movable eccentrically driven crimping member.
