PROBLEM TO BE SOLVED: To provide a method and apparatus for accurately and efficiently producing a flexible synthetic resin hose formed with mouth parts on both ends, and including the mouth parts having a desired length and shape.SOLUTION: A hard cylindrical member-producing process part A is provided on a base part of a molding shaft 11, and a process part B for producing a hose body 1 at a speed faster than that of a production speed of the hard cylindrical member-producing process part is provided in the middle part. A hard cylindrical member 2 produced by the hard cylindrical member-producing process part A is cut into a mouth molding member 3, and the mouth molding member 3 is brought into contact with a base end of the hose body 1 produced in the hose body-producing process part B followed by providing a soft synthetic resin coating layer 4 on the mouth molding member 3, and the coating layer 4 is divided into two and the mouth molding member 3 is drawn out so as to form mouth parts 5 and 5 on both ends of the hose body 1. |
