Abstract (en)
[origin: WO02051717A1] The invention relates to a multiple chamber tube, comprising at least two chambers (7, 7'), a tube head (4) and closable removal holes (5) in correspondence with the number of chambers (7, 7'), said tube consisting of an assembly of at least two tube pipes (2, 2') that are produced separately and are arranged parallel to one another and a common, rounded outer periphery comprising all the tube pipes (2, 2'). According to the invention, said multiple chamber tube has a tube head (4) that is produced as a single piece by jointly pressing all tube pipes (2, 2'). Said head contains separation walls (6) connected to the tube pipes (2, 2'), the number of walls corresponding to the number of said tube pipes (2, 2'), wherein the ends of the edges of the bodies of the pipes (2, 2') are simultaneously surrounded with molten material and are firmly connected to one another after hardening.
