<p>PROBLEM TO BE SOLVED: To provide a pipe making apparatus the assembling work and disassembling work of which can be performed easily in a short time so that a period necessary for the work of regenerating an existing pipe is shortened and a regenerated pipe having high precision is formed efficiently.SOLUTION: A pipe making apparatus 1 includes: a circular frame body 2; an engaging roller 8 to be disposed on the inner peripheral side of an engaging region of a profile 100; and a drive unit 4 for supplying the profile 100 toward the engaging roller 8 from the inner peripheral side of the engaging region. The frame body 2 is formed into such a shape that the front stage part of the engaging region is opened to one end side of a rotary shaft of the engaging roller 8. The drive unit 4 includes at least one pair of pinch rollers 41 comprising a pair of an outside surface roller 51 and an inside surface roller 61, which are rotary driven while interposing the profile 100 therebetween. The pinch rollers 41 are arranged to be press-contacted with/parted from the profile 100. The profile 100 can be removed freely from the space between the pinch rollers 41.</p> |
