ABSTRACT:
A self-contained, transportable apparatus for inserting a flexible liner having a leading end and a trailing end into a pipe comprises an inversion means or insertion conduit, and means for sealingly clamping the leading end of the liner with a fluid tight seal to the insertion conduit or inversion means. A conveyer means having an entry end and an exit end is provided for conveying the liner to the insertion conduit or inversion means. In one embodiment, the conveyer means is comprised of a single conveyer which is movable between a generally horizontally oriented transport position and a generally sloped operating position. Another embodiment of the invention comprises two separate conveyers aligned in end-to-end relation, the two conveyers being movable between a transport position in which both conveyers are generally horizontally oriented, and an operating position in which the distal ends of the conveyers are higher than the remainder of the conveyers. Feed control means are provided for controlling the rate of movement of the liner into the pipe and means are provided for moving the conveyers between the transport position and the operating position.
