  • Process for continuous consolidation for obtaining a stratified material and device for its implementation
    Patent number: 7727452
    Abstract: A process for continuous consolidation of at least one fold (22, 24), whereby the process includes unwinding a unit that consists of the at least one fold (22, 24) that is placed between two strips (26, 28) continuously along at least one curved path, the at least one fold (22, 24) being placed between guiding elements and a strip (26) to the right of the curved path to heat the at least one fold (22, 24) at least at the curved path and to exert tension on the strip (26) so that the latter compresses the at least one fold (22, 24) at least at the curved path, characterized in that it includes using strips (26, 28) whose width is greater than that of the at least one fold (22, 24) so as to be in contact on both sides of the at least one fold (22, 24).

  • Process for continuous consolidation for obtaining a stratified material and device for its implementation
    Publication number: 20070113974
    Abstract: The object of the invention is a process for continuous consolidation of at least one fold (22, 24), whereby said process consists in unwinding a unit that consists of said at least one fold (22, 24) that is placed between two strips (26, 28) continuously along at least one curved path, said at least one fold (22, 24) being placed between guiding means and a strip (26) to the right of the curved path to heat said at least one fold (22, 24) at least at the curved path and to exert tension on said strip (26) so that the latter compresses said at least one fold (22, 24) at least at said curved path, characterized in that it consists in using strips (26, 28) whose width is greater than that of said at least one fold (22, 24) so as to be in contact on both sides of said at least one fold (22, 24).
