Patent number: 11383469Abstract: In building tyres, an intermediate portion of a carcass structure is built at a time on a respective forming drum within an intermediate forming line. The forming drum with the intermediate portion of the carcass structure is made available at a first transfer location. The intermediate portion of the carcass structure is completed through n completion locations with n?1 and then transferred for the subsequent assembling with a crown structure to a second transfer location. At an operating moment in which the first transfer location is occupied by a forming drum coming from the intermediate forming line or intended for the intermediate forming line, from one to n locations selected from the n completion locations and the second transfer location are occupied by respective forming drums.Type: GrantFiled: June 10, 2019Date of Patent: July 12, 2022Assignee: PIRELLI TYRE S.p.A.Inventors: Gianni Portinari, Davide Conti, Luigi Antonio Badolato

Patent number: 11298900Abstract: A carcass sleeve including a carcass ply and a pair of annular anchoring structures is fitted around a toroidal forming drum arranged in a first radially contracted operational condition. The carcass sleeve is toroidally shaped against a radially inner surface of an annular contrast element. The forming drum is positioned inside the carcass sleeve and is concurrently expanded towards a second operational condition. Upon reaching the second operational condition, the toroidally shaped carcass sleeve is coupled to the forming drum. The forming drum, coupled to the carcass sleeve, is adapted to be transferred in proximity of an application device of additional components externally to the carcass sleeve.Type: GrantFiled: November 30, 2016Date of Patent: April 12, 2022Assignee: PIRELLI TYRE S.P.A.Inventors: Gaetano Lo Presti, Gianni Mancini, Maurizio Marchini, Gianni Portinari

Patent number: 10940653Abstract: A process and apparatus for manufacturing tyres for vehicle wheels includes the step of building, on a forming support, a belt structure including at least one reinforcing structure of the so-called zero-degree type. The reinforcing structure is formed by depositing a continuous elongated reinforcing element on a deposition surface arranged in a radially outer position with respect to the forming support. The aforementioned deposition includes the step of exerting, through at least one element made from magnetic material, a magnetic attraction on a portion of the continuous elongated reinforcing element arranged at at least one pressing member and moving said at least one pressing member toward the forming support until the continuous elongated reinforcing element is brought into contact with the deposition surface.Type: GrantFiled: March 3, 2016Date of Patent: March 9, 2021Assignee: PIRELLI TYRE S.p.A.Inventors: Luigi Antonio Badolato, Pietro Dale′, Gianni Portinari

Patent number: 10800122Abstract: In a process for building tyres for vehicle wheels, a carcass sleeve is arranged on a shaping drum including two half-drums and two supports. Each support is operatively associated with one of the half-drums and carries a plurality of turning-up levers having free ends positioned close to the respective half-drum. Two annular anchoring structures are disposed around the carcass sleeve and each of the two supports is locked to the respective half-drum by interposing only stiff mechanical elements in mutual contact between the support and the half-drum. The carcass sleeve is shaped in a toroidal conformation, by setting a threaded shaft in rotation and moving the half-drums close to each other.Type: GrantFiled: July 6, 2017Date of Patent: October 13, 2020Assignee: PIRELLI TYRE, S.p.A.Inventors: Mauro Bigogno, Gianni Portinari, Pietro Dale'

Patent number: 10730198Abstract: Within tyre manufacturing, a reinforcing structure of the tyre, such as the zero-degree layer of the belt structure, is made by an apparatus having devices for guiding a continuous elongated element towards a forming drum, devices for applying the elongated element against a laying surface of the drum, and a cutting unit to cut off the continuous elongated element when application has been completed. Once the cutting operation has been carried out, the free end of the continuous elongated element is set to a grip position downstream of the cutting unit, through a reciprocating slider and a threading element blocking the continuous elongated element with respect to the slider when the latter moves towards the forming drum.Type: GrantFiled: May 23, 2017Date of Patent: August 4, 2020Assignee: PIRELLI TYRE S.P.A.Inventors: Mauro Bigogno, Gianni Portinari

Patent number: 10245797Abstract: In an apparatus for building tires for vehicle wheels, a forming drum is loaded on a shuttle movable on a guide along a deposition line. The shuttle is moved on the guide in the two running directions to bring it to dispensing stations of semifinished products disposed in at least some deposition locations positioned in space succession along the deposition line. At each of the dispensing stations, at least one semifinished product is laid on a radially external surface to the forming drum carried by the shuttle for forming at least one component of a tire. The shuttle is moved on the guide in a different sequence from the space succession of the deposition locations along the deposition line.Type: GrantFiled: June 27, 2012Date of Patent: April 2, 2019Assignee: PIRELLI TYRE S.p.A.Inventors: Gianni Portinari, Pietro Dale, Gian Luigi Bosio

Publication number: 20170151739Abstract: A process for building tyres for vehicle wheels includes feeding to at least one work station an elongated element provided with two service fabrics and wound on a storage coil. The aforementioned feeding includes unwinding, the elongated element from the storage coil, removing the two service fabrics from the elongated element, and collecting each of the two service fabrics on a respective collecting member. Each service fabric can thus be subsequently used independently from the other. For example, one service fabric can be reused while the other can be disposed. The removal and collection of the two service fabrics occurs simultaneously with the unwinding of the elongated element, so as not to increase the overall building time of the tyre being processed.Type: ApplicationFiled: December 28, 2016Publication date: June 1, 2017Applicant: Pirelli Tyre S.p.A.Inventors: Gianni PORTINARI, Francesco STEGAGNO, Pietro DALE'
