Abstract

L'invention concerne un appareil (1) de production comprenant des cylindres (13, 14) rotatifs aspirant des portions de feuilles (23, 24) dans des évidements (131, 141) formés dans la surface des cylindres afin de former des parties en creux (211, 221) et pressent les feuilles (23, 24) de chaque côté de manière à les coller par fusion. Des dispositifs chauffants (16) sont installés à l'extérieur des cylindres (13, 14). Un matériau de remplissage est introduit dans les parties en creux (211, 221) au moyen d'une buse (171) de remplissage installée à proximité de l'emplacement dans lequel les feuilles sont placées entre les cylindres (13, 14). Des moyens (18) de découpage placés en aval des cylindres (13, 14) comprennent deux cylindres (181) pourvus d'arêtes de découpage dépassant à leur surface.
