Machine for welding hollow articles and process for welding these articles, for example half-shells of a plastic fuel tank, using the technique of hot-plate welding, in which the mirror is in the form of separate elements which can be moved independently. Particular processes in which the articles to be welded together are preshaped by pressing against cold-plate elements, which might not be plane, by stretching or compressing the side walls of the articles or by pressing against the walls of a mould. Process applied to the manufacturer of injection-moulded/welded fuel tanks. Use of the machine for manufacturing such tanks.

The winder comprises a central driving carrier tube (1) and winding drums (2) equipped with self-blocking systems (3) for receiving reeling mandrils (4) arranged successively round the central driving carrier tube, the said drums (2) each being connected to this tube by means of a magnetic coupling (16), (17), (18) located inside the said tube (1) and connected, on the one hand, rigidly to this tube (1) and, on the other hand, to the drum (2), in said winder the connection between the magnetic coupling (16), (17), (18) and the drum (2) being made via a speed multiplier (6), (6'), (6'), (13) likewise arranged in the central driving carrier tube (1). The winder allows a reeling of a series of widths cut from the web material, this being carried out with controlled winding tensions.
