20100276068 | PROCESS FOR MANUFACTURING TYRES FOR VEHICLE WHEELS AND APPARATUS FOR BUILDING A CARCASS STRUCTURE OF A TYRE FOR VEHICLE WHEELS - A process for manufacturing tyres for vehicle wheels includes building on a forming support a carcass structure including at least one carcass ply, and, at at least one end edge of the carcass ply, at least one annular anchoring structure including at least one substantially circumferential annular insert and at least one filling insert associated with the at least one substantially circumferential annular insert. Building the carcass structure includes positioning the annular anchoring structure on the carcass ply by moving the substantially circumferential annular insert into contact with an end edge of the carcass ply by means of a special positioning member, pulling down the filling insert on the end edge of the carcass ply and turning up a free end portion of the end edge of the carcass ply so as to form a turned up end portion of the carcass ply including the annular anchoring structure. The pulling down of the filling insert on the end edge of the carcass ply is carried out by a special pulling down member while the substantially circumferential annular insert is retained in a contact position with the end edge of the carcass ply by the positioning member. | 11-04-2010 |
20110108187 | PROCESS AND APPARATUS FOR ASSEMBLING TYRES - In an assembly station, a carcass sleeve and an outer sleeve manufactured along respective building lines are mutually coupled. Integrated into the assembly station are engagement devices that can be alternatively-coupled to an auxiliary drum carrying an outer sleeve and to a building drum carrying a carcass sleeve. The building drum is engaged on the assembly station before removal of the auxiliary drum. A grip unit picks up the outer sleeve from the auxiliary drum associated with the engagement devices in order to position it around the carcass sleeve carried by the building drum. | 05-12-2011 |
20120312455 | PNEUMATIC TIRE MOLDING METHOD AND MOLDING APPARATUS - A pneumatic tire molding method and apparatus enable a side member to be attached to a tire component member set on an external circumferential surface of a rigid inner mold with intimate contact while preventing deformation of the side member surface shape. An annular recess in an annular holder covers an area corresponding to a tire side section of a carcass material on an external circumferential surface of a circular-cylindrically shaped rigid inner mold having substantially the same shape as a profile of an internal circumferential surface of a tire to be manufactured. Air is sucked from a space between the recess and carcass to reduce space pressure. A holding part is arranged inside the recess, has a holding surface having the same shape as a side member surface, and attaches the side member to the reduced pressure area. Remaining tire components are attached to complete a green tire. | 12-13-2012 |
20140352872 | BELT PLY FEEDING SUPPORT FRAME AND FEEDING METHOD THEREOF - The belt ply feeder and a feeding method thereof comprise: when a belt ply is conveyed to the front end of a conveying forming board, a force is exerted by a perpendicular adjustment device to drive a conveying forming board bracket to swing upward and rotate around a pivot shaft of a rack to positions at which the upper surface of the conveying forming board is tangential to the periphery of a belt ply drum. According to this arrangement, the belt ply is tangential to the belt ply drum all the time and a belt ply is in firm contact with a belt ply drum regardless of the size of the belt ply drum when wrapping the belt ply around the belt ply drum. Accordingly, the quality of tire shaping can be improved. | 12-04-2014 |
20150328852 | METHOD OF APPLYING PLY TO A TIRE BUILDING DRUM - A method for applying a sheet of flexible material to a cylindrical body is described. The sheet of material may be ply or a tire building component such as a liner. The method includes the steps of receiving the sheet of flexible material onto a conveyor belt of a conveyor table, wherein the conveyor belt can translate in the X direction, wherein the conveyor belt has a plurality of rollers rotatably mounted on the conveyor belt so they can rotate about an axis aligned with the X direction. The method further includes aligning a lateral edge of the sheet with an edge guide of the conveyor table by tilting the conveyor table and then tilting the conveyor table back to a level position. The method further includes moving a front edge of the conveyor table adjacent the cylindrical body; and applying the sheet onto the cylindrical body. | 11-19-2015 |
20160144583 | PROCESS AND APPARATUS FOR BUILDING TYRES FOR VEHICLE WHEELS AND TYRE FOR VEHICLE WHEELS - A process and an apparatus for building tyres and a tyre for vehicle wheels are described. A substantially cylindrical carcass sleeve, having at least one carcass ply, is formed by laying consecutively adjacent strip-like elements one after the other around the circumferential extension of a substantially cylindrical deposition surface. Circumferentially consecutive strip-like elements are laid one after the other to 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. | 05-26-2016 |

20140261976 | METHOD FOR MANUFACTURING PNEUMATIC TIRE - In a method for manufacturing a pneumatic tire, molding of a green tire has an assembly step of bonding an inner liner and an unvulcanized rubber sheet with end portions thereof in a width direction being displaced from each other by 50 mm to 500 mm in the width direction to manufacture a laminate, cutting the laminate to have a constant length corresponding to a width of a drum to manufacture a cut sheet, and a joining step of winding the cut sheet on entire circumference of the drum such that a cut surface thereof extends in a circumferential direction of the drum and the inner liner is disposed on an inner surface side, and joining the end portions of the inner liner and joining the end portions of the unvulcanized rubber sheet such that positions of the joined end portions are displaced by a constant distance. | 09-18-2014 |
