Date Feb. 29, 1996Pipelines are lined by inserting a lining pipe R out of a long profile beltlike member to be supplied and wound involutely within the pipeline. A jointing mechanism and a guide roller block are arranged around a mounting frame. The lining pipe R is produced while it rotates on its axis in response to rotary drive by the jointing roller block. An additional lining pipe is formed out of a belt like member to be supplied anew and ahead of the already formed pipe, which is left behind. A rigid mounting frame enables lining pipes of a specific diameter to be formed. Also, a flexible mounting frame helps to cope with a pipeline which is rectangular in cross-section. In addition, the already formed lining pipe can be large in diameter by feeding the belt like member at a higher level than the jointing mechanism which is traveling and sliding the joints of adjoining portions of the already formed beltlike member.
