Patent ID: 6994818

Claim:
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.
