Abstract

PURPOSE: To manufacture a high precision of tyre by keeping outer periphery length of a cylinder constant which is constituted by an arched segment.
CONSTITUTION: Rollers 26, 27 provided on ends of a pair of support members 14, 15 mounted on an arched segment 11 constituting a cylinder 13 which is long in periphery length and also on another segment 12 with short periphery length are positioned on a horizontal plane of taper zones 23, 24 of an annular member 25, and the cylinder 13 is opened by engaging a projection 36 of the members 14, 15 with a stopper 37 of the member 25 to form a green tyre. Next, a pressurized fluid in a cylinder casing 34 is discharged, and the member 25 is moved leftward by a coil spring 30. Then an angle of inclination of a slope of the taper zone 24 is taken greater than a slope of the taper zone 23, the roller 27 is moved quicker than the roller 26, the segment 12 and the member 15 are moved radially larger than the member 14 of the segment 11, and the cylinder 13 is contracted in bore, thus demounting the molded green tyre.
