a machine and method for providing a folded liner for insertion into a pipe , comprises an upper section and a lower section . a flattened heated thermoplastic liner is fed downwardly through the upper section to the lower section , where it is redirected and fed substantially horizontally from the lower section . the flattened liner introduced to the upper section is broadly indented at one side of the liner and is then more acutely indented to provide loops disposed side - by - side in a substantially horizontal direction . the lower section reorients the loops so that they are stacked side - by - side in a substantially vertical direction . the liner is cooled as its leaves the lower section to maintain its cross - sectional configuration . the upper section is separable from the lower section , and portions of the upper and lower sections are displaceable and removable to facilitate insertion of the liner into the machine and removal of the machine from the liner .
