摘要： An expandable bladder has at least one first layer of butyl material and one second layer of silicone material, radially external to the first layer. The first and second layers have an undulated interface profile defining mechanical-engagement elements between the first and second elastomer materials. A process for manufacturing bladder as well as a tire molding and vulcanizing apparatus incorporating the bladder.

摘要： A robot arm having seven axes of actuation imparts to a toroidal support a circumferential distribution motion about its own geometric axis simultaneously with controlled transverse distribution displacements in front of a dispensing organ of a strip of elastomeric material. The strip thus forms a plurality of turns, the orientation and mutual superposition whereof are controlled in such a way as to control the thickness variations to be conferred to a component of a tire being manufactured, based on a pre-determined laying scheme pre-set on an electronic computer. The rotation of the toroidal support is controlled in such a way as to obtain a peripheral speed of application exceeding the theoretical feeding rate of the strip, able to be increased or decreased as needed to form turns with reduced or, respectively, enlarged cross section.

摘要： Method, process and plant for building tires for vehicle wheels wherein: in a service position of a carcass structure building line, a forming drum is associated with a pair of support elements including a first support element and a second support element; the forming drum is moved, associated with the pair of support elements, in a deposition line in the carcass structure building line; and the forming drum is transferred from the deposition line to a subsequent work station of the carcass structure building line. The transfer from the deposition line to the subsequent work station includes dissociating the forming drum from the second support element, keeping the forming drum associated with the first support element; transferring the forming drum, associated with the first support element and dissociated from the second support element, to the subsequent work station; dissociating, in the subsequent work station, the first support element from the forming drum, leaving the forming drum in the subsequent work station; and transferring the first support element, dissociated from the forming drum, into the service position.
