Abstract: A plant for building different models of green tyres for vehicle wheels, including a plurality of workstations using elementary semi-finished products is described. A first carcass structure of a first model of tyre is built on a first forming support, in a first workstation, the first carcass structure including at least one first carcass ply obtained from a first elementary semi-finished product, and at least one first pair of annular reinforcing inserts. The first forming support is delivered to a bypass device to go beyond at least one second workstation without transiting through it.

Abstract: A process for building tyres employing a forming drum having circumferentially consecutive sectors that are radially movable between a contracted condition and an expanded condition in which the sectors are radially moved away from a geometric axis in order to define a radially external abutment surface. Each sector has circumferentially opposite coupling portions each having circumferential projections alternated with circumferential cavities. The projections of each sector are slidably engaged in the respective cavities of circumferentially adjacent sectors. From at least one of the projections, at least one support wing is extended having a first side and a second side that are respectively opposite. The first side coincides with a portion of the abutment surface and the second side at least partially overlaps one of the projections belonging to an adjacent sector.

Abstract: A process for building tyres provides for building a carcass sleeve around a forming drum having an application diameter and two lateral half-portions axially moveable relative to each other. The carcass sleeve comprises at least one carcass ply coaxially engaged around each of the axially opposite end flaps thereof to an annular anchoring structure defining a fitting diameter smaller than the application diameter. The building of the carcass sleeve comprises: applying and stopping a leading end of a semi-finished product in form of continuous strip cut to size against a continuous surface of the forming drum; winding the semi-finished product in form of continuous strip cut to size circumferentially around the forming drum; joining a trailing end of the semi-finished product to the leading end at said continuous surface. The continuous surface is extended only partly around the forming drum. The semi-finished product, except for the leading end and the trailing end, is laid against a discontinuous circumferential surface of the forming drum adjacent to the continuous surface and belonging to the two lateral half-portions.

Abstract: A method of controlling deposition of a continuous elongated element in building a tire for vehicle wheels, includes: feeding an initial end of a continuous elongated element of elastomeric material through a slit bounded by a first roller and a second roller of a calender; retaining the continuous elongated element against a peripheral surface of the first roller; laying the initial end of the continuous elongated element against a deposition surface; rotating the calender around an oscillation axis that is substantially coincident with a contact generatrix between the first roller and the second roller; and dragging along the continuous elongated element together with the deposition surface.

Abstract: In an assembly station a carcass sleeve and an outer sleeve manufactured along respective building ones are mutually coupled. Integrated into the assembly station are engagement devices that can be alternatively coupled to an auxiliary drum carrying an outer sleeve and to a building drum carrying a carcass sleeve. A grip unit picks up the outer sleeve from the auxiliary drum associated with the engagement devices in order to position it to a location radially external to the carcass sleeve carried by the building drum associated with the engagement devices in place of the auxiliary drum. Shaping devices that can be operatively coupled to the building drum cause radial expansion of the carcass sleeve so as to enable the latter to be coupled to the outer sleeve retained by the grip unit.

Abstract: A method for managing the continuous feeding of an elongate element wound on reels to a station for building a tire, wherein the elongate element is continuously supplied from an unwinding device of successive reels. When the terminal end of the elongate element wound on a first reel leaves said first reel, the method provides for: the first reel to be moved away from the unwinding device on a first movable carriage; a second reel, successive to the first reel, and mounted on a second movable carriage, to be positioned in place of the first reel; and the terminal end of the elongate element previously wound on the first reel, to be joined to the starting end of the elongate element wound on the second reel.

Abstract: 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.
