  • Device for the manufacture of self-sustaining cups of thin paper
    Patent number: 6641515
    Abstract: A frustoconical matrix and a punch of a complementary shape and coaxial to the former can be brought together to shape an inserted sheet of thin paper. The matrix has a cylindrical peripheral surface along which a beading member comprising a cylindrical foil is slidable in a close running fit. A shoulder extends coaxially to the punch to define a pit having a cylindrical internal wall having a diameter smaller than the outside diameter of the beading member. Heating means are controllable to heat the shoulder to a temperature such that the pit is expanded to a diameter of close running fit between its internal wall and the beading member.
