Abstract: An apparatus for preparing rolled pieces of pastry includes at least four adjacent rollers having parallel axes, being capable of defining a substantially cylindrical cavity, being adapted to rotate in the same direction and being adapted to rotate at a same peripheral speed. Means are provided for forming and then closing an admitting gap between two of the rollers for admitting pieces to be rolled into the cavity for rolling. Means are provided also for forming a releasing gap between two of the rollers for releasing rolled pieces from the cavity.

Abstract: Pastry material is rolled by admitting partially folded pastry material into a substantially cylindrical cavity enclosed by at least four rollers which rotate in the same direction at the same peripheral speed. A gap is formed between rollers for admitting the pastry material into the cavity where it is then rolled by the rollers rotating at the same peripheral speed at a speed sufficient for rolling. After rolling, the rolled pastry material is released from the cavity from a gap between rollers.

Abstract: Method and apparatus for manufacturing a food product in which an edible filling material is completely enclosed in an edible coating material, comprising outer, intermediate and inner spaced apart concentrically arranged extrusion conduits; means for extruding the coating material continuously through the channel between the outer and intermediate conduits to form a tube of coating; means for extruding the filling material intermittently through the channel between the intermediate and inner conduits so that it forms a filling within the tube of coating; means for mechanically isolating the filling material, on interruption of extrusion, from the filling within the tube of coating; means for extruding further coating material alternately to the extrusion of the filling material, through the inner conduit so that it flows within the tube of coating at the rear end of the filling; and means for cutting the extruded tube cross-sectionally between positions where filling is located.

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.

Abstract: A process 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. The cutting and folding operation is carried out by an oscillating knife positioned above the conveyor belt which has a cutting edge extending laterally across the width of the conveyor belt, and 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 thereby causing the forward edge of the pastry sheet to be lifted up and folded over. The knife 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.

Abstract: A method and apparatus for disintegrating soft food materials. A disintegrating element having screw threads and cutting edges on the periphery of the threads is rotated about its axis and reciprocated in directions substantially parallel to a surface of a mass of the material to be comminuted. The cutting edges engage and comminute the material at such surface.
