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).
