SPINNING MACHINE

PROBLEM TO BE SOLVED: To provide a spinning machine capable of reducing noise in a hydraulic circuit and saving power.SOLUTION: In a spinning machine 1, a feed mechanism 20a feeding a tailstock mold 13 in a workpiece pressing direction, a feed mechanism 20c feeding a molding roller 15 in a workpiece diameter direction, and a feed mechanism 20b feeding the molding roller 15 in a workpiece rotational axis direction are constituted by hydraulic units 2 independent of one another, respectively. Each hydraulic unit 2 comprises: a hydraulic cylinder 21 including a reciprocating piston rod 22; a bi-directional rotation hydraulic pump 23 connected to the hydraulic cylinder 21 and including two supply-discharge ports supplying or discharging a working fluid for driving the piston rod 22 of the hydraulic cylinder 21 to reciprocate; and a servomotor 24 driving the bi-directional rotation hydraulic pump 23 to rotate in either a normal direction or an opposite direction. By controlling a rotational speed and a rotational direction of the servomotor 24 for each hydraulic unit 2, a position of the piston rod 22 of the hydraulic cylinder 21 is controlled.
