Patent number: 10213977Abstract: A carcass ply is built on a forming drum by application of a plurality of strip-like elements by the steps of: setting a width of these strip-like elements, setting a width of the overlapped part between two adjacent strip-like elements, setting a fitting diameter of the forming drum by calculating a corresponding extension of a radially external laying surface, and calculating a whole number of strip-like elements to be applied. The whole number of drip-like elements is applied by rotating the forming drum around a geometric rotation axis thereof, and applying pairs of strip-like elements by means of a first laying unit and a second laying unit located close to opposite portions of the forming drum relative to the geometric rotation axis.Type: GrantFiled: April 14, 2016Date of Patent: February 26, 2019Assignee: PIRELLI TYRE S.p.A.Inventors: Maurizio Marchini, Cesare Emanuele Amurri, Marco Cantu, Gianni Mancini, Giorgia Sgalari

Patent number: 9339980Abstract: A carcass ply is built on a forming drum by application of a plurality of strip-like elements, through the steps of: setting a width of these strip-like elements, setting a width of the overlapped part between two adjacent strip-like elements, setting a fitting diameter of the forming drum, calculating a whole number of strip-like elements to be applied. The whole number of strip-like elements is applied by rotating the forming drum around a geometric rotation axis thereof, and applying pairs of strip-like elements by means of a first and second laying unit located close to opposite portions of the forming drum. When the calculated whole number of strip-like elements is an odd number, the first laying unit is shifted along an adjustment path orthogonal to the geometric rotation axis and substantially tangent to the radially external laying surface of the forming drum.Type: GrantFiled: August 6, 2013Date of Patent: May 17, 2016Assignee: Pirelli Tyre S.p.A.Inventors: Maurizio Marchini, Cesare Emanuele Amurri, Marco Cantu, Gianni Mancini, Giorgia Sgalari

Patent number: 7911332Abstract: A wheel having a controlled pressure includes a rim associated with a tank adapted to be filled with a fluid to a first pressure; a tire mounted on the rim and having an inner volume inflated to an operating pressure at a reference temperature, the operating pressure being lower than the first pressure; and at least one valve assembly adapted to establish a communication between the tank, the inner volume of the tire and the external environment. The valve assembly includes a command valve, an exhaust valve and a compensation valve operatively associated with each other. The command valve controls communication between the tank and the inner volume of the tire. The exhaust valve is connected to the external environment, to the inner volume, to the command valve and to the compensation valve. The compensation valve is connected to the exhaust valve and the command valve.Type: GrantFiled: April 23, 2004Date of Patent: March 22, 2011Assignee: Pirelli Tyre S.p.A.Inventors: Renato Caretta, Pier Giuseppe Piantanida, Stefano Sangiovanni, Maurizio Marchini, Giorgia Sgalari
