| 264501000 | Producing toroidal work (e.g., tire, etc.) | 11 |
| 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 |
| 20090174122 | Process and Apparatus for Producing Pneumatic Tyres - A green tyre is built on a forming drum and then transferred to a bead moulding and pre-vulcanisation station where each bead of the tyre is moulded by tightening it between two axially opposite clamping surfaces respectively carried by an axially external annular locating element and an axially internal annular locating element consisting of radially expandable circumferential sectors. The tightened beads can be pre-vulcanised through heat supply by means of electric resistors integrated into the axially external annular locating elements. The tyre with the tightened and possibly pre-vulcanised beads is transferred to a moulding cavity having an inner wall substantially conforming to the shape of an outer surface of the moulded tyre to carry out moulding and complete vulcanisation of the tyre. | 07-09-2009 |
| 20090212467 | Expandable Bladder - An expandable bladder for manufacturing pneumatic tyres is used in combination with a vulcanisation apparatus including, for example, a mould having a plurality of sidewall plates and tread sectors that, when the mould is closed, delimit a moulding cavity suitable for housing the green pneumatic tyre to be cured. The expandable bladder includes an elastomeric material obtained by curing an elastomeric composition which includes at least one butyl rubber and at least one compound having at least one double bond and an at least partially fluorinated alkyl or polyoxyalkylene chain. | 08-27-2009 |
| 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 |
| 20100327495 | PROCESS FOR PRODUCING PNEUMATIC TIRE - A green tire (G) is formed by stacking a tire component such as a carcass layer ( | 12-30-2010 |
| 20110001273 | BLADDER, AN APPARATUS AND A METHOD FOR SHAPING AND CURING A TIRE - A method, a bladder and an apparatus for shaping and curing a tire, wherein the bladder has two weakened regions corresponding to the shoulder regions of the tire when the bladder is expanded in the cavity of the tire. Upon inflation of the bladder and its expansion in the tire, the bladder contacts first the inner surface of the cavity at the bead regions and progressively the sidewalls, the shoulders and then the center of the tire. The weakened regions are designed to stretch more under a given tension than the remaining regions in order to allow a progressive contact movement of the lateral regions of the bladder with the sidewalls with very little tension and relative movement between the lateral regions of the bladder and the sidewalls of the tire. | 01-06-2011 |
| 20120025430 | PROCESS AND PLANT FOR PRODUCING TYRES - A compound plant for processing elastomeric compounds for tyres with both a high quality and a high throughput includes at least one batch mixing device in combination with at least one multi-shaft continuous mixing device having a high number of shafts. For example, the multi-shaft continuous mixing device could be a ring extruder having a plurality of co-rotating screws disposed to form a ring. In operation, a first elastomeric compound is discharged from the at least one batch mixing device and processed with the at least one multi-shaft continuous mixing device to obtain a second elastomeric compound | 02-02-2012 |
| 20120133086 | MEASURING TIRE PRESSURE IN A TIRE MOLD - Pressure sensors may be used to directly measure the pressure between a green tire and a curing apparatus during shaping and/or during curing. | 05-31-2012 |
| 20120223463 | METHOD FOR VULCANIZING VEHICLE TIRES USING A HEATING PRESS - Method and device for vulcanizing vehicle tires using a heating press and a heating bladder. The method includes positioning a tire blank in the heating press, feeding steam into the heating bladder, stopping the supply of steam into the heating bladder, raising an internal pressure in the heating bladder to a predetermined setpoint value by feeding nitrogen into the heating bladder, and consistently maintaining the internal pressure of the heating bladder at the predetermined setpoint value through a pulsating input of nitrogen into the heating bladder occurring at least temporarily over a specific time. | 09-06-2012 |
| 20120319333 | Method of Fabricating Stents From Blow Molded Tubing - Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stent manufacture and fabrication of a stent therefrom are disclosed. | 12-20-2012 |
| 20130087953 | Tire Curing Bladders - An elastomeric composition for a curing bladder comprises isobutylene based elastomer, curative and a hydrocarbon polymer modifier comprising monomers selected from the group consisting of piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, amylenes, and combinations thereof, wherein the cyclic pentadienes comprise at least 10 weight percent of the monomers by total weight of the monomers. Also disclosed are a tire curing bladder made from the elastomeric composition, a tire curing press containing the bladder, a method of making the tire curing bladder, an improvement to the process of making the tire curing bladder to improve processability of the mixture and fatigue life and DeMattia cut growth, a method of making a tire using the tire curing bladder, and an improvement to the process of making a tire to extend a pull point of the curing bladder and/or to reduce the curing time for the tire construct. | 04-11-2013 |
