CABLE PROTECTING PIPE AND APPARATUS FOR PRODUCING THE PIPE

摘要

PROBLEM TO BE SOLVED: To simply produce a cable protecting pipe which is excellent in flexibility and can reduce frictional resistance and tensional resistance generated between it and the cable to be inserted.

SOLUTION: With the use of a strip-like member which has joining parts for fusing by lapping when wound spirally at both ends and forms a flexible recess for making it have flexibility to deflection applied to the pipe on a surface to be the inside of the cable protecting pipe, the joining parts at both ends of the strip-like member are wound while being lapped spirally, and the lapped joining parts are formed cylindrically by fusing.
