Abstract
An apparatus for manufacturing a liner for installation in an existing conduit in reduced form. The apparatus includes an extruder for extruding heated thermoplastic pipe material through a die to form a tubular shape, a shaping station for shaping the extruded tubular plastic material to the reduced form, a cooling station to cool the liner so that the liner maintains the reduced form and a reheating station to render the liner pliable to be put in suitable form for storage. The liner may be spooled on itself in a layered condition or on a solid spool.
