Method and apparatus for manufacturing tyres for vehicle wheels

Номер: US20120027880A1

Автор: Alfredo Balini, Stefano Cazzanti

Принадлежит: Pirelli Tyre SpA

In a method for manufacturing tyres for vehicle wheels, a green tyre, once formed, is transferred into a vulcanisation mould and pressed against the holding walls of a moulding cavity. Concurrently with the pressing step, a fluid present between the green tyre and the holding walls is evacuated through vent valves. The tyre is brought into contact with the closing head of each valve so as to push it toward a closed position of the valve itself. The closing head has a distal portion facing the moulding cavity and includes at least one grip element for the tyre blend, so that the closure member is pulled toward the open position while the moulded and cured tyre is moved away from the inner surface of said moulding cavity.

A machine that removes the bead wires from tires for the purpose of reclaiming the wire and recycling of the tire. The bead of the tire is placed over a drive wheel and tension rollers, the tension rollers move away from the drive wheel which stretches the bead against the drive wheel. The drive wheel is driven by a drive system and causes the bead to rotate. As the bead rotates a blade contacts the inner periphery of the bead and severs the rubber and reinforcement material. Directly following the blade are two plates that are spaced apart approximately equal to the diameter of the bead wire. The plates push the rubber and reinforcement material off of the bead wire as the bead rotates. 1one or more v-groove tension rollers positioned above the drive wheel that ride on bearings and shafts that are mounted on a carriage assembly that moves in a direction away from the drive wheel by means of any appropriate device such as a pneumatic or hydraulic cylinder thereby causing the tire bead to be stretched tight around the drive wheel and tension roller(s) so that the tire bead rotates,a cutting blade mounted within the inner diameter of the tire bead to a blade holder that causes the blade to move in a radial outward direction relative to the tire bead,a stripping die composed of two parallel plates that are mounted with a gap between them that allows only the bead wire to pass though and are fastened to an arm that allows the stripping die to move in a radial outward direction relative to the tire bead..

A pneumatic tire is provided which includes an outer circumferential rubber tread and a supporting carcass. A rubber inner liner is disposed inwardly from the supporting carcass. A built-in sealant layer is situated adjacent to an innermost removable barrier layer and disposed inwardly from the rubber inner liner. The built-in sealant layer provides self-sealing properties to the pneumatic tire. The pneumatic tire, with its innermost removable barrier layer, keeps the sealant layer from sticking to a tire-building apparatus during tire assembly and, after curing of the assembled tire, is eventually removed to permit gas from the built-in sealant layer to become part of the tire's inflation air to prevent or reduce instances of inner liner blister formation.
