Abstract: A continuous rotary hamburger grill has means for forming unshaped balls or scoops or other quantums of ground meat into hamburger patties as it presses them into cooking relation with the rotating grill plate. The meat quantums deposited on the grill plate at a loading station are carried thereby beneath an adjustably mounted, sloping pressure plate which presses them into sticking relation with the grill plate and compresses them into patties of uniform thickness. A flexible liner of non-stick material, e.g., Teflon, underlies the pressure plate so that the patties slide thereunder. To reduce moisture loss and improve cooking, a flexible cover sheet of non-stick material rides on the top of the patties as they travel through a cooking zone. The free edge of the pressure paper plate liner underlies the adjacent edge of the flexible cover sheet to provide means for feeding the patties beneath such cover sheet.
