Abstract (en)
[origin: WO2007137374A1] The invention relates to manufacture of thin-walled tube-packs. The machine consists of a unit (23) for positioning a pre-fabricated tube head (12) and a mechanism (1) for feeding a strip foil (2) to a fixed mandrel (3) with preset shape, mechanism (4) for bending the foil (2) and unit for pressing and welding (5). An M-step transfer mechanism (7) is in a working seat (8i). The machine has also a shaping unit (9), welding unit (10) and cutting unit (11). The unit (23) for positioning a pre-fabricated tube head (12) is situated at a preceding working seat (8<SUB>m-n</SUB>) (n = 1 to 4). The welding unit (10) is positioned under the working seat (8<SUB>1</SUB>), coaxially to mandrel (3) and (13). A driving mechanism (16) is for the mandrel (13). The cutting unit (11) is situated between the clamps (15) and shaping unit (9). The foil being located between the mandrel (3) and a restructure (18). The gap (20) of the non-closed restructure (18) is intended for providing a contact between the mechanism (5) for pressing and welding and the overlapped ends (6) of the bent foil.
