METHOD AND DEVICE FOR THE PRODUCTION OF CONVEX SHELLS MADE OF POLYSTYRENE FOAM

摘要

The invention relates to a method and a device for the production of convex shells (2), in particular food shells made of polystyrene foam. The method comprises the following steps: (a) cutting a foam block into individual blanks shaped like plates or strips (1.1 ...1.n); (b) mounting and moving the blanks in a row on a horizontal plane (E); (c) producing an intermediate plate from a blank by contacting and lightly pressing both flat surfaces of the blank each with with a heated, flat pressure surface (14, 14') to achieve superficial melting; (d) shaping the intermediate plate in a mould formed from a heated top die (20) and bottom die (22') to form a food shell; (e) ejection or removal of the food shell.
