PROBLEM TO BE SOLVED: To provide a simple and efficient rotation control apparatus for a matter to be controlled in its rotation like a mold in a manufacturing apparatus for uniformly molding a non-circular fiber reinforced plastic pipe or arbitrarily changing molding wall thickness partially. SOLUTION: A rotation control apparatus contains the hollow circular form 1 arranged to the outer surface of a matter to be controlled in its rotation and having a plurality of rotary position detecting dogs and an origin position detecting dogs attached to the outer periphery thereof, a drive control apparatus for controlling the rotation of the hollow circular form 1, sensors 17a, 17b for detecting the rotary position detecting dogs and origin position detecting dogs attached to the hollow circular form 1 and a sequence control apparatus 18 inputting the signal received by the sensors 17a, 17b to process the same to specify the rotary position of the hollow circular form 1 and output a preliminarily inputted signal. By this constitution, the output of the drive control apparatus is controlled corresponding to the output signal of the sequence control apparatus 18 to control the rotational speed of the hollow circular form 1. |
