| 20090008024 | Method and Apparatus for Manufacturing Pneumatic Tyres - A green tyre disposed on a toroidal support is introduced into a vulcanisation mould. The mould is closed through axial approaching of a pair of half shells acting against the sidewalls and the tread band of the tyre. Circumferential sectors set to operate against the tyre tread band are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tyre against the toroidal support. Subsequently the sectors are centripetally approached to cause penetration of forming ridges movable in through slits into the tread band, concurrently with a step of full moulding and vulcanisation of the tyre carried out through admission of steam under pressure into the tyre itself. | 01-08-2009 |
| 20090008835 | Method and apparatus for manufacturing pneumatic tyres - A green tyre disposed on a toroidal support is introduced into a vulcanisation mould. The mould is closed through axial approaching of a pair of sidewall plates acting against the sidewalls of the tyre. Circumferential sectors set to operate against the tyre tread band are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tyre against the toroidal support. Subsequently, the sectors are centripetally approached for penetration into the tread band concurrently with a step of full moulding and vulcanisation of the tyre carried out through admission of steam under pressure into the tyre itself. | 01-08-2009 |

| 20100032873 | Method and Apparatus for Manufacturing Pneumatic Tyres - A green pneumatic tyre is built on a rigid toroidal support externally having a forming surface of a conformation corresponding to the inner shape of a tyre. The green tyre engaged on the expandable toroidal support is introduced into a vulcanisation mould and submitted to a vulcanisation cycle. During vulcanisation, axial moving apart of side portions of the toroidal support is caused so as to press the beads and sidewalls of the tyre against the vulcanisation mould. | 02-11-2010 |
| 20110072664 | PROCESS AND APPARATUS FOR BUILDING TYRES - A carcass ply is applied around an outer surface of a building drum according to an application diameter larger than the fitting diameter of a tyre. Coaxially engaged around each of the end flaps is an annular anchoring structure defining the fitting diameter. A pair of sidewalls is manufactured by laying of a continuous elongated element in the form of approached coils on the carcass sleeve. An outer sleeve, including at least one belt structure possibly associated with a tread band, is coaxially centered around the carcass sleeve. Through axial approaching of two halves forming the building drum, the carcass sleeve is shaped into a toroidal configuration to determine application of same against a radially internal surface of the outer sleeve. | 03-31-2011 |

The available elongation of the belt in an intermediate zone between the equatorial plane, and the shoulder is greater than the available elongation corresponding to the equatorial plane. The aforementioned intermediate zone extends at least in a range centred on a camber angle of ±35°. | 03-31-2011 |
