Abstract
Abstract Thin, crisp, baked snacks having a chip-like appearance are continuously produced from a cooked, shredded laminate by substantially compressing the laminate without deleteriously affecting the attainment of a substantially uniform, visually apparent shred or woven pattern in the final, baked product. Additionally, at least substantially all, or all of the individual shred layers maintain their integrity and may be viewed in the final, baked product. The substantial compression is achieved by supporting the laminate of cooked, net-like sheets on a conveyer belt, and passing the supported laminate and belt between at least one pair of counterrotating compression rolls. Substantial movement or slippage of the laminate relative to the belt which would substantially disrupt or distort the shred pattern of the laminate is avoided. The substantial compression of the laminate provides a thin, flat, chip-like appearance rather than a puffed or thick biscuit or cracker appearance. The compressed laminate is preferably partially cut into triangular shaped pieces having flattened, blunted or rounded corners by a rotary cutter so that the apex or point of a triangle in one row does not touch or intersect the apex or point of another triangle located in an adjacent row.
