| 摘要 |
This invention relates to a process for producing a flexible hose combination comprising a first vacuum hose (1) with a large diameter, an inner wall (6) and an entrace (17), in which first vacuum hose (1), in longitudinal direction, at least one second tube (2) with a small diameter is attached through its external wall (7), over a predetermined part of its length, wherein a hot adhesive (5) in the liquid state is applied in longitudinal direction to said predetermined part of the external wall (7) of the second tube (2), and said predetermined part of the second tube (2) is introduced through said entrance (17), in longitudinal direction into a predetermined part of the first vacuum hose (1) almost simultaneously with the application of the adhesive, after which said predetermined part of the first vacuum hose (1) is compressed in such a way that the inner wall (6) of the first vacuum hose is contacted with the adhesive (5), whereby, during compression, said predetermined part of the first vacuum hose (1) is supported over at least part of its length. The invention also relates to a device for carrying out the above described process. |
