| 20100024985 | SHAPING FORMER AND SYSTEM FOR BUILDING GREEN-TIRE INCLUDING THE SAME - A former used for shaping a green tire into a toroidal shape and a green tire building system including two formers are disclosed. The former comprises: a pair of bead-lock devices supported by a rotatable tubular shaft in which a central shaft is disposed; a rotational-to-linear motion converter converting rotational motion of the central shaft relative to the tubular shaft to linear motion for causing the bead-lock devices to come close to each other or to get away from each other; a single electric motor; and a clutch for switching the transmission of the rotational motion of the motor to (A) only the central shaft to change the distance between the bead-lock devices or (B) both of the tubular shaft and central shaft to rotate the bead-lock devices. The building system comprises a turntable on which the two formers are disposed towards different directions so that by turning the turntable, each of the formers positions towards a first drum and a second drum in turn. | 02-04-2010 |

| 20120012256 | Tire Building Method and Rotational Transfer Device for Drum Transfer Support Base in Tire Building Process - The invention can perform building in a process for building a carcass band or a belt/tread band of a tire, in which two drum transfer support bases ( | 01-19-2012 |
| 20120279661 | METHOD AND PLANT FOR MANUFACTURING TYRES FOR VEHICLE WHEELS - A method and a plant for manufacturing tyres for vehicle wheels wherein the method includes the steps of: a) building in a building station a substantially cylindrical carcass structure; b) manufacturing in a finishing station a substantially cylindrical sleeve including a tread band applied at a radially outer position with respect to a belt structure including at least one belt layer. Step b) includes the steps of assembling a first belt structure at a first working position on a first auxiliary drum of the finishing station; applying a tread band at a second working position at a radially outer position with respect to a second belt structure previously assembled on a second auxiliary drum of the finishing station, positioning the first auxiliary drum supporting the first belt structure at the second working position; and positioning the second auxiliary drum supporting the substantially cylindrical sleeve thus obtained at a picking position of the finishing station. | 11-08-2012 |
| 20140231023 | METHOD AND APPARATUS FOR MANUFACTURING TYRES FOR VEHICLE WHEELS - An apparatus for manufacturing tyres for vehicle wheels includes devices designed to form a green tyre, a vulcanisation mould having holding walls defining a moulding cavity, and devices for transferring the green tyre into the moulding cavity. The vulcanisation mould includes a plurality of vent valves, at least one of which includes a duct and a closure member having a closing head that is axially movable relative to the duct. The closing head is movable between a closed position, at which the closing head forms a contact seat, and an open position, at which the closing head and inner wall confine a passage for connection with the moulding cavity. | 08-21-2014 |
| 20140251544 | METHOD AND APPARATUS FOR MANUFACTURING PNEUMATIC TYRES - On a building drum, anchoring structures to beads, carcass plies, a belt structure and/or other annular composite components are sequentially assembled with a liner, sidewalls, sidewall inserts, under-belt inserts or other annular elastomer components. Each of the sidewall inserts, sidewalls, or under-belt inserts is made as a one piece construction in a service station operating far away from the building drum for storage on a movable storing device. Actuating members operating on the movable storing device carry the annular elastomer components from the service station to the building drum. A transfer member picks up the annular elastomer components from the movable storing device to transfer them to the building drum. | 09-11-2014 |
| 20140374026 | THREE DRUM TIRE-FORMING MACHINE AND MATERIAL-CONVEYING METHOD THEREFOR - The triple-drum forming machine for the tire comprises a tire body drum, a belted layer drum and a forming drum, which are arranged on the same horizontal axis, wherein a portal frame for conveying a raw material is vertically arranged above the tire body drum, the belted layer drum and the forming drum; the transverse central line of the portal frame overlaps with the axial center lines of the tire body drum, the belted layer drum and the forming drum; the tops of the tire body transfer ring component and the belted layer transfer ring are respectively connected to the portal frame in a sliding manner; the portal frame comprises a horizontally arranged truss and a plurality of groups of vertically arranged upright posts; the horizontally arranged truss is connected with the vertically arranged upright posts. | 12-25-2014 |
| 20150290889 | PROCESS AND PLANT FOR BUILDING TYRES FOR VEHICLE WHEELS - Method, process and plant for building tires for vehicle wheels wherein: in a service position of a carcass structure building line, a forming drum is associated with a pair of support elements including a first support element and a second support element; the forming drum is moved, associated with the pair of support elements, in a deposition line in the carcass structure building line; and the forming drum is transferred from the deposition line to a subsequent work station of the carcass structure building line. The transfer from the deposition line to the subsequent work station includes dissociating the forming drum from the second support element, keeping the forming drum associated with the first support element; transferring the forming drum, associated with the first support element and dissociated from the second support element, to the subsequent work station; dissociating, in the subsequent work station, the first support element from the forming drum, leaving the forming drum in the subsequent work station; and transferring the first support element, dissociated from the forming drum, into the service position. | 10-15-2015 |
| 20150375465 | PROCESS AND PLANT FOR BUILDING TYRES - A plant for building tyres includes a plurality of working locations, at least one first working location being associated with at least two loading/unloading locations, a proximal one and a distal one, each of said working locations and loading/unloading locations being associable with a forming drum. The production cycle is controlled by the method of: (i) loading a first forming drum into the at least one first working location; (ii) loading a second forming drum into the loading/unloading location; (iii) at the end of the working provided in the at least one first working location, unloading the first forming drum into the proximal loading/unloading location. | 12-31-2015 |
| 20160101580 | PROCESS AND PLANT FOR PRODUCING TYRES FOR VEHICLE WHEELS - A plant and a process for producing tyres wherein the process includes the steps of: a) building a green tyre on a toroidal support in a building line of a tyre production plant; b) transferring the green tyre and the relevant toroidal support from the building line of the production plant to a first holding unit; c) transferring the green tyre and the relevant toroidal support from the first holding unit to a vulcanization line of the production plant; d) moulding and vulcanization the green tyre in the vulcanization line of the production plant; e) separating the moulded and vulcanized tyre from the relevant toroidal support; f) transferring the toroidal support, separated from the relevant tyre, from the vulcanization line to the first holding unit; and g) transferring the toroidal support, separated from the relevant tyre, from the first holding unit to the building line of the production plant, wherein steps b) and g) are carried out through a first transfer device and steps c) and f) are carried out through a second transfer device different from the first transfer device. | 04-14-2016 |
