    摘要： A method for managing elongate elements in a plant for building tyres, comprises: • - providing a device (100) for storing and supplying at least one elongate element (3) comprising a first rotation shaft (14) and a second rotation shaft (15) which are coaxial and which can be controlled selectively between a first operating configuration, in which the first rotation shaft and the second rotation shaft are fixedly joined to each other, and a second operating configuration, in which said shafts can freely rotate independently of each other, • - maintaining the first rotation shaft (14) and the second rotation shaft (15) in the first operating configuration when the device (100) is in storage and transport operation and • - moving the first rotation shaft (14) and the second rotation shaft (15) into the second operating configuration when the device (100) is in the course of winding or unwinding said at least one elongate element on or from the first or second rotation shaft.

    摘要： Method for controlling the extrusion of a semifinished product in a tyre building process, said method comprising: providing a semifinished product (1) at the exit of an extrusion assembly (2), said semifinished product (1) comprising at least: a first component (11) made of at least one first material; a second component (12) made of at least one second material, different from said first material; said semifinished product (1) having accumulated heat during an extrusion carried out in said extrusion assembly (2); making a first verification for verifying at least one of: presence of said second component (12) and arrangement of said second component (12) relative to said first component (11), wherein said first verification comprises: detecting first electromagnetic radiations (Rl) representative of a heat emission from said semifinished product (1) while said semifinished product (1) is releasing said accumulated heat; based on said first radiations (Rl) detected, determining first detection parameters (DPI) representative of at least one of the presence of said second component (12) and/or the arrangement of said second component (12) relative to said first component (11); generating a first notification signal (NS1) as a function of said first detection parameters (DPI). An apparatus (100) is also described for controlling the extrusion of a semifinished product in a tyre building process.

    摘要： There are described a green tyre, a tyre, a process and a plant for building tyres. The process comprises building a carcass structure (110, 210) and a crown structure (130, 230) comprising a belt structure (140, 240) and a tread band (150, 250), and associating the carcass structure with the crown structure. The building of the crown structure envisages the building of the belt structure on a drum (520) and the deposition of the tread band in a position radially outside the belt structure. The deposition of the tread band comprises the provision of a predetermined elastomeric material (531) in a hot - extrusion device (530), the extrusion from the extrusion device of a band (531) of elastomeric material having a width equal to the predetermined width of the tread band and a thickness smaller than the predetermined thickness of the tread band, and the hot¢deposition of the band onto the belt structure in at least two overlapping layers.
