Abstract
A cyclic crimping mechanism for producing coherent plural-layer food products from food assemblies, each food assembly including a bottom patty covered by a top patty (other patties, food slices, or condiments are usually positioned between the top and bottom patties), uses a cyclically, intermittently actuated conveyor to locate each food assembly at a crimping position for a predetermined crimping interval; in sequence, a confinement tool is moved down to an actuated position to define peripheral limits for the food product, a tamping tool is pressed down onto the food assembly to reduce air entrapment, and a crimping tool presses the periphery of the top patty into the bottom patty to seal them together in a coherent food product, after which these tools are all elevated to rest positions clear of the crimping position and the conveyor operates to move the finished food product away and position a new food assembly at the crimping position to start the crimping cycle anew. The crimping tool may include pins that pierce the central part of the food assembly for additional air release.
