Patent number: 9365006Abstract: A compound plant for processing elastomeric compounds for tires 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.Type: GrantFiled: April 2, 2014Date of Patent: June 14, 2016Assignee: Pirelli Tyre S.p.A.Inventors: Stefano Testi, Alan Bottomley, Alessio Longoni

Patent number: 8967850Abstract: A multiscrew extruder device for production of elastomeric compounds is intended for manufacturing tires for vehicle wheels. The device includes a holding body; a mandrel inserted in the holding body extending along a longitudinal axis and delimiting an annular chamber with the holding body; and a plurality of extrusion screws disposed in the annular chamber and parallel to the longitudinal axis. A first circuit for a heat-exchange fluid for temperature control is formed in the mandrel and includes a central channel extending in the mandrel along the longitudinal axis and a plurality of parallel peripheral channels extending in a peripheral portion of the mandrel close to the annular chamber and in fluid communication with the central channel.Type: GrantFiled: July 8, 2008Date of Patent: March 3, 2015Assignee: Pirelli Tyre S.p.A.Inventors: Alan Bottomley, Stefano Testi, Thomas Ponta, Alessio Longoni

Publication number: 20120318439Abstract: An extrusion device for producing elastomeric compounds, includes a holding body internally confining a chamber and at least one extrusion screw disposed in the chamber. The device further includes a plurality of interchangeable extrusion heads alternatively installed on the holding body at a discharge opening of the chamber. The choice of using a type of head rather than another or leaving the discharge opening free is carried out based on the physico-chemical features of the elastomeric compound to be treated, so as to maintain the temperature and/or pressure of the outgoing compound under critical threshold values for such a compound.Type: ApplicationFiled: December 16, 2010Publication date: December 20, 2012Inventors: Stefano Testi, Alessio Longoni, Alan Bottomley

Patent number: 6908221Abstract: A closed mixer includes a mixing chamber, a pair of rotors, and a pressing ram. The pressing ram is moveable between a resting condition, which allows introduction of material into the mixing chamber, and a working condition. A method of processing polymer-based mixtures and compounds in the closed mixer includes introducing material into the mixing chamber, moving the pressing ram from the resting condition to an upper end-of-stroke position, and moving the pressing ram from the upper end-of-stroke position to a lower end-of-stroke position. A position-time profile of the pressing ram is controlled during moving the pressing ram from the upper end-of-stroke position to the lower end-of-stroke position.Type: GrantFiled: May 24, 2004Date of Patent: June 21, 2005Assignee: Pirelli Pneumatici S.p.A.Inventors: Antonio Proni, Danile Balasso, Alan Bottomley
