20080202667 | Method and Plant For Manufacturing Tyres For Vehicle Wheels - A method for manufacturing tyres for vehicle wheels includes: a) building in a building station a substantially cylindrical carcass structure including at least one carcass ply operatively associated with annular anchoring structures axially spaced apart from each other; b) manufacturing in a finishing station a substantially cylindrical sleeve including a tread band applied at a radially outer position with respect to a belt structure including at least one belt layer including reinforcing cords; b1) assembling a first belt structure at a first working position on a first auxiliary drum of the finishing station; b2) applying a tread band at at least one second working position with respect to a second belt structure on at least one second auxiliary drum by laying down green elastomeric material; b3) positioning the first auxiliary drum supporting the first belt structure at the second working position; b4) positioning the second auxiliary drum supporting the substantially cylindrical sleeve at a picking position; and c) transferring the substantially cylindrical sleeve from the picking position a radially outer position with respect to a carcass structure built in the meantime in the building station. Steps b1) to b4) are repeated cyclically. Steps b1) and b2) and steps b3) and b4) are carried out at least in part simultaneously. | 08-28-2008 |
20090199954 | Method for producing a bead filler material with a bead core - A bead filler material having a generally toric shape is produced by winding and laminating a ribbon-like rubber strip. In conjunction with completing the production of the bead filler material, in order to form linear grooves radially extending on a surface of one side of the bead filler material in the thickness direction and contributing to smooth discharge of air, the ribbon-like rubber strip is helically winded and laminated around a bead core which is concentrically arranged on a rotatable base, thereby transferring radially extending linear projections provided on the rotatable base to a surface of the bead filler material contacting the rotatable base to form the linear grooves over the whole circumference of the bead filler material. | 08-13-2009 |
20090266474 | METHOD OF AND APPARATUS FOR MANUFACTURING A TIRE BEAD - A filler rubber being triangular-shaped in cross section can be held in an upright posture to be stuck to an outer peripheral surface of a bead core and a leading end and a trailing end can be butted against each other to be joined without the generation of crack. A filler rubber (F) is held in an upright posture to be wound around an outer peripheral surface of a bead core (C) supported by a rotary support body ( | 10-29-2009 |
20100116415 | APPARATUS AND METHOD FOR PRODUCING TIRE - In forming a green tire by arranging a plurality of carcass cords on a support member and disposing bead cores, the carcass cords are precisely and accurately disposed at predetermined positions. A plurality of carcass cords (C) are arranged over the entire circumference of a core ( | 05-13-2010 |
20120318440 | METHOD AND APPARATUS FOR FORMING AN ANNULAR ELASTOMERIC TIRE COMPONENT - A method of forming a tire apex and bead assembly is disclosed. The method and apparatus includes mounting a bead in a rotatable bead holder, rotating the bead and bead holder and extruding one or more passes of a continuous strip of elastomeric material onto the outer surface of the bead, and shaping the one or more passes of elastomeric material between two opposed rotating rollers. | 12-20-2012 |
20140345785 | TIRE BEAD TRANSFER RING AND TRANSFER METHOD THEREOF - The invention provides a tire bead transfer ring and a transfer method thereof. The tire bead transfer ring and the transfer method adopts a complete magnetic attachment method and a photoelectric detection approach to improve the stability of picking, clamping and transferring of tire beads, prevent tire beads from slippage and deformation and ensure the coaxiality and verticality between tire beads and a tire building drum. The tire bead transfer ring comprises a left semi-ring ( | 11-27-2014 |
20150068668 | BEAD APEX RUBBER-FORMING METHOD, AND BEAD APEX RUBBER-FORMING DEVICE - The present invention forms bead apex rubber with good precision on the outer circumferential surface of the bead core. A molding process, in which unvulcanized rubber is made to flow into a bead apex molding chamber that is surrounded by surfaces that include the outer circumferential surface of a circular bead core and the bead apex rubber is formed directly on the outer circumferential surface of the bead core that is rotating around the core axis, is provided. The molding process comprises: a tip forming step that forms the leading end of the bead apex rubber; a middle section forming step that sequentially forms the bead apex rubber to be continuous with the leading end; and a joining step to join the back end and the leading end of the bead apex rubber by inflowing the unvulcanized rubber therebetween. | 03-12-2015 |
20150360429 | BEAD FORMING APPARATUS AND FORMING METHOD - A bead forming apparatus including: a rotatable drum having a plurality of divided bodies dividedly arranged along a circumference and being adapted to be wrapped therearound with a belt-shaped bead filler having a short base and two other long sides in an annular shape; a plurality of erection arms provided along the circumference and swingably supported by the divided bodies of the rotatable drum so as to erect the bead filler by swinging the erection arms; and a swing device for swinging the erection arms; and a plurality of slide members provided as contact portions of the erection arms that come into contact with the bead filler so that the bead filler can be radially slidable relative to the erection arms. | 12-17-2015 |
