The apparatus for installing a repair liner/sleeve within a pipeline includes a rigid tube supported above a manhole or excavation leading to the entry of the pipeline to be repaired. A rigid tube is supported on a plurality of legs aligned above the manhole, with a vertical tube attached to the rigid tube and extending downwardly into the hole. A hollow tubular shoe is attached to the lower end of the vertical tube, and is curved to redirect a liner/bladder assembly from the vertical orientation within the vertical tube to a horizontal orientation aligned with the pipeline to be repaired. The tubular shoe includes a plurality of upper rollers and lower rollers between which the liner/bladder assembly will be directed for reorientation from the vertical tube to the horizontal pipeline. The rigid tube includes a pivotal lid which will seal the upper end of the rigid tube, to permit pressurization of the rigid tube, flexible tube, and shoe. An air inlet port in the lid permits the introduction of pressurizing fluid, and a second port in the lid receives a control line for attachment to the liner/bladder assembly, for removal of the bladder after repair of the pipeline.
