Abstract (en)
[origin: WO9601179A1] A method of producing a plastic tray (5) having a peripheral edge region (11) terminating in a terminal edge (12) which is deformed inwardly out of a wrap path around the tray (5) is disclosed. The peripheral edge region (11) of the tray (5) is heated to render it malleable. The region (11) is deformed by bringing an appropriately configured die into engagement with the malleable region (11) and rolling the region (11). The region (11) is then cooled such that it sets and hardens in the deformed condition. In a preferred form, the tray (5) is heated by heating the die (25) which is used to roll the edge region (11). This invention also extends to a method of attaching the two elements of a two-piece tray to each other and to apparatus for carrying out the method of the invention.
