Abstract:
A CIPP liner feeder system for efficiently feeding CIPP liner into an air inversion unit. The CIPP liner feeder system generally includes a feed roller attached to an air inverter unit that is adjustable to a first position for feeding a CIPP liner into the air inverter unit from the front or a second position for feeding a CIPP liner into the air inverter unit from the rear. A motor is connected to the feed roller to rotate the feed roller in a first direction when the feed roller is in the first position and a second direction when the feed roller is in the second position. A connecting structure is attached to the air inverter unit for connecting to a lifting/lowering structure of a tractor.
