The invention relates to a multi-chamber tube with at least two chambers and a tube head, with closable withdrawal apertures corresponding to the number of chambers and consisting of an accumulation of at least two separately produced tubular pipes arranged parallel to one another with a rounded external periphery common to all tubular pipes. According to the invention it comprises an integral tube head produced by pressed molten portions and common to all tubular pipes and containing the partition walls corresponding to the number of tubular pipes and connected thereto, molten material simultaneously flowing around the edge ends of the tubular members which are rigidly connected to one another after curing.

What is claimed is: 1. Method for producing a multi-chamber tube with at least two chambers (7, 7') and a tube head (4 ), with closeable withdrawal apertures (5) corresponding to the number of chambers (7, 7'), at least two separately produced tubular pipes (2, 2') arranged parallel to one another

What is claimed is: 1. Method for producing a multi-chamber tube with at least two chambers (7, 7') and a tube head (4 ), with closeable withdrawal apertures (5) corresponding to the number of chambers (7, 7'), at least two separately produced tubular pipes (2, 2') arranged parallel to one another being manufactured with a common rounded external periphery, comprising: producing in the number of desired chambers (7, 7') tubular pipes (2, 2') which are drawn onto partial mandrels, bringing the partial mandrels and the tubular pipes (2, 2') together, introducing the partial mandrels brought together with the tubular pipes (2, 2') into a press moulding device and press moulding a plastic portion to produce a tube head (4) with partition walls (6), while simultaneously connecting both the tube head (4) and the partition walls (6) to edge ends of the tubular pipes (2, 2'), which have axial notched edges ( 3) at least at two spaced apart points wherein, the edge ends of the tubular pipes (2, 2') are also rigidly connected to one another during the press moulding; the edge ends of the tubular pipes (2, 2') are also rigidly connected to one another during press moulding. 2. Method for producing a multi-chamber tube according to claim 1, wherein the tubular members (2, 2') are shaped along the axial notched edges (3), viewed in cross-section, into partial circle-shaped portions. 3. Method for producing a multi-chamber tube according to claim 1, wherein the tubular pipe sections adjacent to one another are at least partially connected to one another in their longitudinal extension.
