20080314524 | Method for single line tire ply construction - A method for positioning an end of a cord line at a target location on an annular tire building surface, includes positioning a cord line segment over the target location; tensioning the cord line segment between leading and trailing segment ends; and severing the cord line segment at a point between the leading and trailing segment ends so that the resultant cord line end is at the target location on the tire building surface. Transporting a severed portion of the cord line segment away from the annular tire building surface may be conducted and a tire cord ply may be constructed to extend from the cord line segment about at least a portion of the annular tire building surface prior to severing the cord line segment. | 12-25-2008 |

20110180214 | METHOD AND APPARATUS OF ADHERING AND BUILDING BELT MEMBER - A belt member on a supply conveyor is transferred onto a building drum from an inclined distal end portion while holding on both side edge portions in the width direction thereof. A supply conveyor places the belt member thereon and a hand device which includes holding members, extending in the feeding direction of the supply conveyor. In a state that a distal end portion of the belt member on the supply conveyor is held on a lower surface of the press plates, of the hand device, the belt member is transferred to the building drum along with a feeding operation of the supply conveyor and, at the same time, the belt member is adhered by pressing to a peripheral surface of the building drum from a distal end portion thereof while rotating the building drum along with the transfer of the belt member. | 07-28-2011 |
20110214817 | METHOD AND APPARATUS OF FABRICATING CARCASS MEMBER FOR TIRE - The invention can efficiently provide a carcass member constituting a carcass layer of a radial tire, particularly, a carcass member a direction of a cord of which constitutes an angle of substantially 90° relative to a tire circumferential direction, and can easily adjust a length in accordance with a size, one piece of a cord (C) is continuously passed through a rubber coating die ( | 09-08-2011 |
20110297324 | METHOD AND APPARATUS OF ADHERING BELT EDGE TAPE - According to the present invention, in adhering a belt edge tape ( | 12-08-2011 |
20120222820 | PROCESS FOR MANUFACTURING TYRES FOR VEHICLE WHEELS - A process and apparatus for manufacturing tyres for vehicle wheels, includes building, on a toroidal support, a carcass structure including at least one carcass ply associated, at axially opposite end edges thereof, with annular anchoring structures, the building step of the carcass structure includes forming at least one reinforcing structure, operatively associated with the annular anchoring structures through deposition on the toroidal support of at least one reinforcing element along a predetermined curvilinear deposition path. The deposition of the at least one reinforcing element includes the steps of: cutting to size a piece of at least one reinforcing continuous band-like element fed by a feeding device along a predetermined feeding direction, deforming the piece obtained according to the curvature of a deposition part of the deposition path intended to receive the piece, and depositing the deformed piece at the deposition part. | 09-06-2012 |
20130206340 | TIRE BUILDING METHOD AND RUBBER STRIP BONDING APPARATUS - The invention can surely accomplish lamination without the generation of voids in building a tire constructed to comprise a plurality of rubber members for a tire when a ribbon-shaped rubber strip (R) is spirally wound and laminated, and uses holding rolls ( | 08-15-2013 |
20130319617 | PROCESS AND APPARATUS FOR MANUFACTURING TYRES FOR VEHICLE WHEELS - Building a carcass structure of a tyre for vehicle wheels includes associating, at each end edge of a carcass ply laying on a forming support, at least one respective annular reinforcing structure obtained by depositing at least one respective reinforcing element. The deposition process includes feeding a continuous reinforced band-like element at a cutting unit, cutting to size at least one first reinforcing element from the continuous reinforced band-like element, moving the first reinforcing element from the cutting unit toward a first end edge of the carcass ply, positioning the first reinforcing element on the first end edge, cutting to size at least one second reinforcing element from the continuous reinforced band-like element, moving the second reinforcing element from the cutting unit toward a second end edge of the carcass ply opposite said first end edge, and positioning the second reinforcing element on the other end edge. | 12-05-2013 |
20140231024 | TIRE BUILDING APPLICATOR MEMBERS AND SYSTEMS - An applicator assembly for applying a cord to a tire-building surface that rotates during tire construction. The applicator assembly includes an applicator member to apply the cord. A first rotary device rotates the applicator member about a first axis that is transverse to the surface. A first translation device moves the applicator member in a first linear path relative to the surface. The applicator member may include a roller and/or a resilient member. A second rotary device may rotate the applicator member and the first rotary device around a second axis substantially perpendicular to the first axis. A second translation device may move the applicator member, the first rotary device, the second rotary device, and the first translation device. A system for applying the cord to a core member may further include a spindle to rotate the core member about the axis of rotation. | 08-21-2014 |
20150298412 | DEVICE FOR BONDING RUBBER STRIP - A rubber strip is bonded with high accuracy to the surface of a non-linear cylinder-like wound body. The space occupied by the device is reduced. Provided is a transporting conveyor having a transporting belt guided rotatably by guiding rollers. A transporting surface of the transporting belt is provided with a transporting surface width centerline extending in a straight line over the entire length thereof. The guiding rollers are distributed into forward-side guiding rollers and backward-side guiding rollers in the transporting direction. Since the forward-side guiding roller is held tiltibly around the transporting surface width centerline, the transporting surface forms a twistable twisting transporting surface portion between a forward-side transporting surface portion supported by the forward-side guiding roller and a forward-side transporting surface portion supported by the backward-side guiding roller. | 10-22-2015 |
20160144584 | PROCESS AND APPARATUS FOR MANUFACTURING TYRES FOR VEHICLE WHEELS - Building the carcass structure of tyres for vehicle wheels includes associating, each end edge of a carcass ply, at least one respective annular reinforcement structure formed by depositing along a circumferential direction a plurality of reinforcement elements having a first length. Such elements are cut to size from a reinforced continuous band-like element fed to a cutting group arranged at a first operative position adapted to allow a barycentric grip of the reinforcement elements. The cutting group can translate along a feeding direction of the band-like element to a second operative position for cutting to size a plurality of second reinforcement elements having a second length different from the first length. The second operative position is defined on the basis of the second length, so as to have a barycentric grip of the second reinforcement elements too. | 05-26-2016 |
