APPARATUS FOR PROCESSING COILED TUBING HAVING TURNS PREBENT TO VARYING RADII OF CURVATURE

摘要

Method and apparatus for processing coiled tubing or other material having turns prebent to varying radii of curvature without unbending the tubing. A coil of tubing is rotatably supported and the turns of tubing from the coil are sequentially separated axially of the coil. The axially separated tubing is guided into and through a processing station. The tubing is maintained on a predetermined path through the processing station by sensing deviation of the tubing from the predetermined path and then directing the tubing into the path in response to the sensed deviation. The trailing end of the tubing is sensed as it passes through the processing station, and further directing of the tubing is discontinued.
