Abstract

PURPOSE: To manufacture a spiral pipe of optional lead angle through a simple operation of an extremely simple construction, by providing a projection in one of the second couple of wheels of three couples of upper and lower hyperboloid wheels arranged on a line, and by allocating the first and the third couples of wheels for feeding and pulling the blank pipe.
CONSTITUTION: A blank pipe P is fed into upper and lower hyperboloid wheels from the right to the left and is inserted along a center line CL; the blank pipe P is fed forward into the apparatus by a wheel 2 of the first couple of wheels in which the narrow round part between the wheels 2a, 2b is adjusted so as to fit to the outer surface of the blank pipe P. When a groove 80 is formed between an upper wheel 4a provided with an impression projection 10 and an lower wheel 4b of the wheels 4 of the second couple, the blank pipe P is given both of the longitudinal linear motion and the rotating motion, so that the groove 80 is spirally formed in the outer surface of the blank pipe P. The lead angle θ0 of this groove 80 is related to angles of inclination θ1, θ2 of upper and lower wheels against the central axis of feeding the blank pipe P and to the longitudinal feeding velocity (v) of the blank pipe P. The pipe P provided with the groove 80 is pulled by wheels 6 of the third couple which collaborates with the wheels 2 to secure the holding and feeding of the pipe P; hereby, the work of the wheels 4 is effectively performed.
