<p>A method for forming a green tyre assembling tyre constituent elements such as a carcass ply, side treads, a belt, a top tread, rubber cushion members and the like. This method comprises the steps of presetting a plurality of elements of rubber cushion material, preliminarily severed into a plurality of pieces, onto at least both side portions of the belt and at predetermined positions on the carcass ply respectively and, with the carcass ply wrapped around a forming drum, simultaneously folding back the side portions of the carcass ply as well as the side treads superposed on the side portion to shape these into a predetermined shape on the forming drum, and then sticking a BT-band comprising the belt and the top tread to a predetermined position on the predetermined shape. Accordingly, tyres with a reproducible quality can be manufactured, and tyre production efficiency can be enhanced.</p> |
