Abstract: The principal object of the invention is to provide a novel system for assembling green tires according to the two-stage process, together with a programmable control which allows the system to perform most of its functions automatically. The system assembles a first stage tire carcass essentially automatically, then removes and transfers completed carcasses automatically to a unique tire assembly drum, onto which the carcasses are automatically loaded. The assembly drum then acts to form each carcass into the desired toroidal shape. Second stage belt-tread stock assemblies are, in the meantime, completed and then automatically transferred into position surrounding the shaped carcasses, joined thereto, and the joined first and second stage assemblies are stitched together forming a green tire. The completed green tires are then taken automatically from the tire assembly drum and launched onto a unique discharge chute device.

Abstract: The forward end of a belt-shaped member is transferred to a predetermined position on the outer circumferential surface of a bladder, and pressurized air is filled into the bladder, while it is rotated. When the bladder has been inflated to a predetermined diameter, the filling of the pressurized air is stopped and at the same time the rotation of the bladder is stopped to set it at the predetermined diameter. The forward end of the belt-shaped member is fixed on the bladder by means of a fixture, and the bladder is rotated together with the fixture to wind and attach the belt-shaped member around and to the outer circumferential surface of the bladder. Thereafter, the fixture is removed from the bladder after completion of the attaching of the belt-shaped member to the bladder.

Abstract: A method of winding a belt-shaped member is used in winding a tire member around a forming drum. A position of a leading end of a tire member is detected to obtain a shifted distance of the leading end relative to the forming drum. The leading end is then transferred to the forming drum, while the leading end is being moved in a width direction to make zero the shifted distance. The leading end is pressed against the forming drum, while the leading end is brought into coincidence with a reference position of the forming drum. The forming drum is then rotated during which the tire member is supplied onto the forming drum. A position of a trailing end of the tire member is detected to obtain a shifted distance of the trailing end relative to the reference position of the forming drum. The trailing end is the supplied onto the rotating forming drum, while the trailing end is moved in a width direction to make zero the shifted distance of the trailing end.

Abstract: A method for cutting to length a strip of tire building material includes the step of feeding the strip of tire building material via a conveying device tangentially to a winding drum. In a further step the strip of tire building material is wound onto the winding drum by rotating the winding drum and a defined pressure is simultaneously applied with a pressure roller during winding until a length of the strip of tire building material corresponding almost to the circumference of the winding drum has been wound onto the winding drum. The rotating winding drum is then stopped and the strip of tire building material is fixed in a first location in the vicinity of a cutter bar that is positioned directly in front of the conveying device. The pressure roller is then moved from its initial position toward the cutter bar along the circumference of the winding drum to thereby tighten the strip of tire building material and fix the strip of material in a second location closely adjacent to the first location.

Abstract: A chuck (4) grasping the front edge or a tire component material (S) which is supplied from a material feeder (3) generates a motional locus through an initial ascending motion and through a forward motion toward the former and through a subsequent descending motion to the former to lay the front edge onto the carcass (T). A pressing mechanism (6) operates to press the introduced material (S) on the carcass (T), and concurrently the former (2) rotates by a predetermined rotation angle to adhere the tire component material (S) onto the carcass (T). Thereafter a cutter assembly (5) operates to cut the tire component material (S) in a length corresponding to the sum of a required length for joint and a full circumferential length of the carcass. The former (2) rotates again to adhere the tire component material (S) onto the full circumference of the carcass (T), and the front edge and a last edge of the tire component material are jointed by the pressing mechanism (6) so that the adhesion is completed.

Abstract: A green tire building process wherein a cylindrical belt (B) comprising a tread (A) and a breaker (3) are applied around a toroidally shaped tire carcass (1) on a tire carcass building drum (13) to assemble a green tire. The breaker cushions (6) are fit to the inner circumferential surfaces of the opposite edge portions of the breaker (3) prior to applying the belt (B) around the tire carcass (1).

Then the breaker and tread are wound onto the breaker cushions to form the belt which is later removed from the belt forming drum before being applied onto the tire carcass.
