ABSTRACT:
Apparatus for preparing a rolled pastry product in which a sheet of pastry material advancing on a conveyor belt is cut and folded into discrete pieces of a predetermined size and then rolled characterized in that the cutting and folding operation is carried out by an oscillating knife positioned above the conveyor belt and having a cutting edge extending laterally across the width of the conveyor belt, which immediately after contacting and cutting through the advancing pastry sheet by means of its cutting edge, ascends and rotates in a direction such that the motional vector of the cutting edge is counter to the conveying direction causing the forward edge of the pastry sheet to be lifted up and folded over, and then descends and rotates in the reverse direction so that the cutting edge contacts and cuts through the advancing pastry sheet behind the folded portion to separate a folded piece from the remainder of the pastry sheet.
