The thermoforming assembly includes feeding devices for moving a continuous strip-shaped semi-finished product along a forwarding path, along which a forming mould is arranged defining a forming cavity delimited by a base wall, a first pair of respectively opposed side walls, and a second pair of respectively opposed side walls. Heating devices operate on the strip-shaped semi-finished product near the forming mould, and forming devices are operatively associated with the forming mould and configured to conform the strip-shaped semi-finished product against the base wall and the side walls defining the forming cavity. At least one of the side walls belonging to the second pair is a movable wall, positionable towards and away from the other side wall belonging to the second pair, to vary the dimension of the forming cavity.

A machine for manufacturing a mask includes a plurality of carriers mounted to a belt so as and having a plurality of molding cavity inserts. A feed station supplies material from a roll so as to form a sheet of material on to the carriers. A shell forming station is configured to press a molding core inserts into the molding cavity inserts so as to form a shape of the mask. A welding station generates a predetermined ultrasonic vibration at a predetermined frequency and a predetermined amplitude so as to weld the sheet of material. A cutting station cuts out the mask from the sheet of material. A mask grabbing apparatus is configured to grab the mask and position the mask for retrieval.

A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.
