Abstract:
1. A method of packaging a foodstuff, the method comprising the steps of sequentially: a) horizontally shifting a plurality of bars above edges of a deposition surface into rest positions with the bars wholly retracted from above the deposition surface and thereafter cutting a plurality of slices of a foodstuff and depositing them on a fusible bottom sheet lying on the deposition surface; b) while maintaining the bars in the rest positions, setting a fusible top sheet down atop the slices on the bottom sheet with edges of the top sheet generally aligned above respective edges of the bottom sheet and the slices between the sheets; c) without horizontally displacing the stack and sheets, displacing the bars from the rest positions to work positions with edges of the bars moving horizontally so that they overhang the surface and are vertically aligned above respective edges of the sheets on the surface; c′) vertically displacing the surface and bars toward each other in the work positions of the bars to compress the sheet edges between the respective bar edges and the surface edges while heating the sheet edges to fuse the sheet edges together; and c″) vertically displacing the surface and bars away from each other; and d) removing the sheets and the slices between them from the deposition surface.
