Abstract (en)

[origin: EP0951990A2] The method comprises in succession the following operating steps: -- the cutting, by means of a die-cutter (21), of a disk (D) from a ribbon (11) of paperlike material which is fed continuously from a storage reel (10); -- the drawing of said disk by means of complementarily shaped mold parts (22-23) and the forming of the bottom and of the lateral wall or walls of the container, the lateral wall or walls having a perimetric flap which is in excess with respect to the depth of the finished container (30); -- the swaging, by means of a beading ring (24), of the excess perimetric flap and the forming of a compacted circular rim (B) which is adapted to give the container (30) self-standing characteristics. <IMAGE>
