Abstract: An apparatus and method for lining sewer pipes that utilize an adjustable form configured to conform to the shape and dimensions of the interior of a man-entry sized pipe line. The adjustable form can be used to position a sheet of liner material immediately adjacent the inner sewer walls. An air cushion system is utilized to reduce friction and drag between the sheet of liner material and form so that the liner sheet can be easily adjusted prior to bonding to the inner walls of the pipe line.
