Abstract
A method and apparatus for interleaving frozen food patties with sheets of protective material (e.g., paper), in which at least a spot of an edible 'adhesive' material adheres each protective sheet to a patty. In one embodiment, a spot of a true adhesive (e.g., honey, sugar solution, etc.) is applied to a protective sheet that is subsequently moved into engagement with a frozen food patty. In another embodiment, at least a spot of an edible heat-activated adhesive material at the interface between a protective sheet and a frozen patty is activated by heat applied through the protective sheet. In this instance, the adhesive may be a separate material which is applied to either the protective sheet or the food patty; on the other hand, the adhesive may comprise moisture in the surface portion of the patty.
