Abstract
1. Method of manufacturing a water hose having inner intermediate walls using a mould which is moved along a mould run and consists of endlessly guided mould halves which, when moving into the linear mould run, are guided in pairs towards one another and closely adjacent to one another in the direction of movement while the mould is closed, and a still thermoplastic hose being fed to the mould and deformed therein under a vacuum, characterised in that, even before two mould halves are moved together, the hose is subjected to a vacuum at least in part of its cross-section, at least one vacuum channel extending into the run-in area of the mould halves as far as the front of the linear mould run so that at least one vacuum hole overlaps the vacuum channel before the mould is closed, and, subsequently, is compressed over part of its cross-section leaving hollow spaces open to form weld marks.
