Abstract: A method for building green tyres includes: feeding an elementary semifinished product with a feeding apparatus; associating an anthropomorphic robotized arm with a forming drum; sending movement commands to the arm to move the forming drum in a working zone, the forming drum being moved while the feeding apparatus is feeding an elementary semifinished product, so that it is laid on the forming drum. Movement commands are sent to the arm, including: determining target coordinates for the arm in order to move the forming drum in the working zone; modifying the target coordinates by a correction function associated with the arm and the working zone, and using the modified coordinates for such movement commands.

Abstract: A first ply and then a second ply, which is superposed on the first ply, are produced on a hoop-type first support. The hoop-type first support has a first receiving surface, to form a laminate. The first and second plies forming the laminate are transferred onto an annular second receiving surface of a core so that the laminate is wrapped on the core until each ply is closed on itself and the laminate is thus closed on itself in a ring about the central axis of the core.

Abstract: A method for building tyres for vehicle wheels is described. Second stage forming drums are moved in a crown structure building line for building respective crown structures. Movement occurs along a first path for building a first part of components of the crown structure and a second path for building a second part of components of the crown structure. Additionally, first stage forming drums are moved in a carcass structure building line for building respective carcass structures. The flow of the second stage forming drums is managed through a first manipulator, while the flow of the first stage forming drums is managed through a second manipulator.

Abstract: Disclosed is a tire building system including a first drum, a second drum and first stations, a first support, a first carrier that carries the first drum with respect to the first support, a second support and a second carrier that carries the second drum with respect to the second support, wherein the first carrier is movable along the first support in a first positioning plane, wherein the second carrier is movable along the second support in the first positioning plane, wherein the first support is arranged for supporting the first carrier from below the first positioning plane and wherein the second support is arranged for suspending the second carrier from above the first positioning plane. The disclosure further relates to a method for positioning the first drum and the second drum with respect to the first stations with the use of the aforementioned system.

Abstract: An apparatus for building tyres for vehicle wheels are described. A substantially cylindrical carcass sleeve, having at least one carcass ply, includes consecutively adjacent strip-like elements laid one after the other around the circumferential extension of a substantially cylindrical deposition surface. Circumferentially consecutive strip-like elements laid one after the other form overlap zones along respective longitudinal edges superimposed on each other. Each overlap zone has, along a longitudinal extension thereof, terminal sections that are laterally opposite with respect to an intermediate section. The intermediate section of each overlap zone has greater width than the width of the terminal sections.

Abstract: A plant for building tyres includes a plurality of working locations, at least one first working location being associated with at least two loading/unloading locations, a proximal one and a distal one, each of said working locations and loading/unloading locations being associable with a forming drum. The production cycle is controlled by the method of: (i) loading a first forming drum into the at least one first working location; (ii) loading a second forming drum into the loading/unloading location; (iii) at the end of the working provided in the at least one first working location, unloading the first forming drum into the proximal loading/unloading location.

Abstract: A first forming apparatus includes a forming drum, a forming unit, a conveyance path, and a conveyance unit that conveys the forming drum along the conveyance path. A tire member is formed with tire components wound on the forming drum by the forming unit. The first forming apparatus also includes a measurement unit that performs, on a downstream side of the forming unit in the conveyance path, measurement on the tire components wound on the forming drum while the forming drum is moving through the measurement unit, in a tire radial direction over a width direction of the forming drum, and an inspection unit that performs inspection on winding states of the tire components based on a measurement result due to the measurement unit.

Abstract: The present invention glues a rubber strip on the surface of a non-right circular cylindrical winding body with good precision. The present invention reduces the space occupied by the apparatus. The tire member-forming apparatus is provided with a transport conveyor with a conveyor belt that is guided by guide rollers so that the conveyor belt is able to circle. The conveyor surface of the conveyor belt is provided with a conveyor surface width center line that extends in a straight line over the entire length thereof. The guide rollers are grouped into guide rollers on the front side of the conveyor direction and guide rollers on the back side of the conveyor direction. The front guide rollers are held so as to be capable of tilting around the conveyor surface width center line. As a result, on the conveyor surface, a twistable twisting conveyor surface section is formed between a front conveyor surface section, which is supported by the front guide rollers, and a back conveyor surface section, which is supported by the back guide rollers.
