Application to butt-joining of the outer return wire of telecommunication submarine cables.

A large number of existing companies are evolving in a reality that reflects more of a patchwork than an overarching vision, even when that patchwork is carried out according to digital best practices.

Process for butt-joining of two metal strips coated on at least one face of a thermoplastic polymer film.

In particular, pressure sensitive adhesive useful for making repulpable articles such as office tape, splicing tapes, labels and similar products.

The butt-joining device (6) comprises means (16) for adjusting the relative position of the rolling means (9) and the soldering and cutting zone to be rolled.

Once all the contours are cut, a new cycle of welding sheets together and cutting contours is started.

The invention relates to a device (6) for butt-joining a product made of strips or webs of material, said device comprising a soldering and cutting workstation (7) and a rolling workstation (8).

If we see the whole thing as a logical self-generation process, we can join the two processes without difficulties, even if the clock cycles are offset.

We decided to equip the Clichy mill with a new oven which would assure higher and better controlled temperatures, thereby facilitating the lamination of the ingots and the soldering of the wires.

With the possibility to make pipes up to 3,000 mm diameter, 53m long (without circumferential welds) and 25 mm thick, we have a unique position in the world.
