Abstract
A method of producing a laminated metal belt with a space corresponding to the thickness of resin between respective ring belts by a step for forming a laminated sheet by bonding the number of metal sheets corresponding to the number of ring belts constituting the laminated metal belts of one unit with resin, a step for forming a seamless cylindrical body having predetermined inside and outside diameters from the laminated sheet, a step for cutting the cylindrical body radially into sections to obtain laminated rings and a step for removing resin from the laminated ring.
Claims40
A method of producing a laminated metal belt in which a plurality of ring belts each having a different circumferential length are laminated in one unit comprising:
- a first step of bonding a plurality of metal sheets together with resin to form a laminated sheet, said laminated sheet having resin between the metal sheets;
- a second step of forming a seamless cylindrical body from said laminated sheet by deep drawing or spinning said laminated sheet;
- a third step of cutting said cylindrical body radially to obtain a bonded laminated ring;
- and
- a fourth step of removing resin from said laminated ring to form said laminated metal belt.
A method of producing a laminated metal belt in which a plurality of ring belts each having a different circumferential length are laminated in one unit comprising:
- a first step of bonding a plurality of metal sheets together with resin to form a laminated sheet, said laminated sheet having resin between the metal sheets and at least one surface of said laminated sheet being bonded to an auxiliary plate;
- a second step of forming a seamless cylindrical body with said auxiliary plate inside by deep drawing or spinning said laminated sheet;
- a third step of cutting said cylindrical body diametrically to obtain a bonded laminated ring;
- and
- a fourth step of removing resin from said laminated ring to form said laminated metal belt.
