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: The invention relates to a food package for controlled heating or cooking of prepared food in hot air, convection, household and microwave ovens.The package comprises a tray (1) including a bottom wall (2) and an upwardly extending peripheral wall (3) which is outwardly curved at its upper end, defining a horizontally extending peripheral rim (4), said peripheral wall and rim being of or at least their inner surface being coated with a microwave radiation-reflecting or opaque material (5) and said bottom wall (2) being of a microwave radiation-transparent material or being easily removable.
