An assembly for introducing a pipe liner into a sewer pipe includes a
launcher defining a passageway through which a resin impregnated pipe
liner and bladder tube assembly passes. An inflatable member mounted to
the launcher assembly is actuatable between an inflatable condition and a
deflated condition. The pipe liner and bladder tube are secured in place
by expanding the inflatable member outward against the inner surface of
the sewer pipe. Air pressure drives the bladder tube and pipe liner into
the sewer pipe and the bladder tube remains in place until the pipe liner
hardens.
