摘要： In a process for building tyres for vehicle wheels, a carcass sleeve is arranged on a shaping drum including two half-drums and two supports. Each support is operatively associated with one of the half-drums and carries a plurality of turning-up levers having free ends positioned close to the respective half-drum. Two annular anchoring structures are disposed around the carcass sleeve and each of the two supports is locked to the respective half-drum by interposing only stiff mechanical elements in mutual contact between the support and the half-drum. The carcass sleeve is shaped in a toroidal conformation, by setting a threaded shaft in rotation and moving the half-drums close to each other. Subsequently, each of the two supports is unlocked from the respective half-drum and the threaded shaft is set in rotation to move each support close to the respective half-drum and lift up the free ends of the turning-up levers until the end flaps of the carcass sleeve are turned up around the annular anchoring structures.

摘要： A tire building drum is disclosed having first and second sets of deck segments, disposed in an alternating configuration about a central shaft. Each of the segments is mounted to a pair of axially movable hub units via an associated scissor linkage. The scissor linkages of the first segments are slidably mounted to the hub units and biased toward a median plane of the tire building drum. When the hub units are separated, the second segments are disposed radially inwardly of and between the first segments. Movement of the hub units toward one another through a first range of motion expands the first deck segments to an expanded diameter of the drum, and movement of the hub units toward one another through a second range of motion expands the second deck segments to allow the second deck segments to be received between the first deck segments.

摘要： Disclosed is a power transmission device of a green tire forming drum apparatus. The green tire forming drum apparatus includes a carcass drum shaft, left and right forming drums mounted to the carcass drum shaft in a laterally symmetrical manner and being movable laterally in an axial direction of the carcass drum shaft, finger mounting supports for moving left and right turn-up fingers, respectively mounted to the left and right forming drums, up and down, and a driving unit for supplying power required for rotation& and later& movement of the forming drums and up/down movement of the turn-up fingers. Power generated by a lower servomotor of the driving unit is transmitted to the forming drums via pull/push plates connected to a ball screw, and power generated by an upper servomotor of the driving unit is transmitted to the turn-up fingers via pull/push plates connected to another bail screw.

摘要： A carcass ply is applied around an outer surface of a building drum according to an application diameter larger than the fitting diameter of a tire. Coaxially engaged around each of the end flaps is an annular anchoring structure defining the fitting diameter. A pair of sidewalls is manufactured by laying of a continuous elongated element in the form of approached coils on the carcass sleeve. An outer sleeve, including at least one belt structure possibly associated with a tread band, is coaxially centered around the carcass sleeve. Through axial approaching of two halves forming the building drum, the carcass sleeve is shaped into a toroidal configuration to determine application of same against a radially internal surface of the outer sleeve.

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.

摘要： This invention relates to a bead lock arrangement for use in tire building equipment, and to tire building equipment utilizing such a bead lock arrangement. A bead lock assembly is disclosed comprising first and second parallel, coaxial, axially spaced bead lock arrangements (13, 14), each bead lock arrangement including an annular, extensible, bead seating ring (38) encircling the radially movable segments (33) of the bead lock arrangement and having, at its radially outermost face, a circumferentially extending bead seating surface (39), and an annular sealing ring (42) positioned coaxial with the respective bead seating ring (38) and disposed adjacent a side face of the respective bead seating ring (38) presented generally towards the bead seating ring (38) of the opposing bead lock arrangement. The use of a bead seating ring (38) and a separately formed sealing ring (42) has considerable advantages over the use of a conventional bead seating ring. The use of a separate, extensible bead seating ring (38) and a non-expanding sealing ring (42) allows the production of less complex items having extended service life.
