Abstract
A launcher assembly includes an outer housing that supports aprons and a nozzle. The nozzle and apron are removable from the base to aid in set up and preparation. Rollers are mounted to ends of the base to aid movement through a sewer pipe. One end of the launcher includes an opening slot for receiving an extended end of the liner. A bladder is banded to a nozzle for inverting the liner. The launcher is held in place by a separately inflatable bellows and pillow. Cameras are mounted to the launcher to provide at least one image on a remote display to aid alignment and installation.
