Feed Roller with Raised Portions for Feeding Dough to Mold Roller

Abstract

A feed roller is formed with a generally cylindrical outer surface having raised portions arranged in a pattern that extends circumferentially around the surface. The raised portions are formed in distinct shapes. Preferably the distinct shapes are chevron shapes that retain dough between successive chevron shapes. The roller preferably has an annular ridge which prevents dough from escaping axially off the edge of the roller. In use, dough is feed between the feed roller and a mold roller. Some of the dough is retained on the outer cylindrical surface of the feed roller to provide a smooth surface for inserting the rest of the dough in mold cavities located in the mold roller.
