Abstract
Abstract In an apparatus and method for selectively determining the orientation of dough pieces, dough pieces are made to fall from an upper conveyor passing around a curved end portion formed at the downstream end thereof. The falling dough pieces hit a bar positioned underneath the curved end portion and land on a lower conveyor positioned under the bar with the orientation reversed or unchanged depending upon whether the dough piece rides on the forward or the rearward side of the bar.
