摘要

The inversion port for feeding a sealant-impregnated inversion hose into a drainpipe to line it is made up of at least two chambers (1, 2) which ensure air-tight feeding of the hose into the pipe. The chambers are divided longitudinally by flexible seals (9a, 9b), between which the hose (7) is fed. - An INDEPENDENT CLAIM is included for the inversion port chambers.
