Abstract: A device including a bedplate (1) that supports a horizontal frame (3) imparted with alternating movement and having several independently moving rotating horizontal circular blades mounted thereon, wherein the blades (10) simultaneously cut loaves (13) of food products placed in vertical loaders (2, 16, 22) fastened to bridges (20) fixed to the bedplate (1), wherein the loaves (13) of product rest on base plates (17) placed transversally on the moveable horizontal frame (3) slightly lower than the plane of the cutting blade (10). The cut slices fall on a bottom conveyor belt (15) where they are collected, and the slices may selectively overlie or overlap previously cut slices. The device may be used to prepare varied sandwiches, "San Jacobos" (breaded and fried meat and cheese), "San Merinos" (breaded and fried fish and cheese), cordon bleu, breaded and fried cuts of meat, and the like.
