| 20120103044 | BEAD WIRE MANUFACTURING METHOD AND MANUFACTURING APPARATUS - A bead wire manufacturing method/apparatus includes a descaling step/device for removing oxide on the surface of a wire rod, a coating liquid adhesion step/device for adhering a coating liquid to the wire rod, wiredrawing steps/devices for performing area reduction workings on the wire rod, and a bluing step/device for bluing the wire rod having been raised to a high temperature through the area reduction workings, in a temperature range of 350° C. to 480° C. Thus, the wire rod having been raised to a high temperature through wiredrawing is blued without being cooled down to effectively utilize the temperature retained therein, so that the method/apparatus is little in energy loss. | 05-03-2012 |
| 20120080139 | RUBBER SHEET JOINTING APPARATUS AND METHOD - A rubber sheet jointing apparatus is provided with first holding means for releasably holding a joint end portion of one of two rubber sheets, second holding means provided movably relative to the first holding means for releasably holding a joint end portion of the other of the two rubber sheets, and operating means for pressure-contacting the end surfaces of the two rubber sheets respectively held by the first and second holding means by moving the second holding means relative to the first holding means. Mutually facing surfaces of the first and second holding means are respectively provided with holder portions which are formed as rugged portions each taking a comb tooth shape and which are able to partly overlap to mesh with each other. | 04-05-2012 |
| 20120064357 | TYRE BEAD WIRE AND PROCESS FOR PRODUCTION THEREOF - A tire bead wire and a process for producing a tire bead where a carbon steel wire rod containing carbon in a range of 0.61% or more to 0.65% or less in weight percent and having a diameter in a range of 5.5 mm to 6.5 mm is wiredrawn through a single wiredrawing process to a predetermined final wiredrawing diameter having a true strain in a range of 2.0 to 4.0 and is turned to a pearlite structure in which ferrite and cementite are drawn in parallel with a narrow interval therebetween. | 03-15-2012 |
| 20110183022 | TIRE VULCANIZATION FORMING MOLD - In a tire vulcanization forming mold which is circumferentially divided into a plurality of segment molds, a plurality of circumferential grooves are formed on each segment mold with spaces in a tire width direction; arc-shape mold blocks are detachably fitted respectively in the plurality of circumferential grooves; a plurality of slit grooves are formed on each mold block to open on side surfaces of the mold block; tread pattern forming blades are detachably inserted into these slit grooves in the tire width direction; and coming-off prevention engaging portions are provided on the slit grooves and the blades. Thus, the tire vulcanization forming mold is capable of enabling the blades to be replaced easily with respect to the segment molds. | 07-28-2011 |
| 20100193137 | DEVICE FOR FOLDING BODY PLY - In a body ply turn-up device, a plurality of arm components are circumferentially arranged to be movable in the axial direction of an operating shaft and to be pivotable radially of the operating shaft, guide members are respectively supported at both sides on an end portion of each arm component to be rotatable about an axis parallel to a pivot axis of each arm component, coil springs are interposed in respective spaces each between two guide members respectively supported on the arm components adjoining to be rotatable about respective arc axes around the operating shaft, and pressing members, which supplementarily cover respective spaces between the coil springs are rotatably supported on the arm components ahead of or behind the coil springs. Thus, the turn-up device can turn up both width-end portions of the body ply by an even pressing force without leaving any spaces in the circumference even in the case of being high in turn-up height. | 08-05-2010 |
| 20080223507 | RUBBER SHEET JOINING APPARATUS AND METHOD - A rubber sheet joining apparatus comprises: a cutting unit for cutting a ribbon of rubber sheet reinforced with cords to generate rubber sheet strips having different lengths; a sheet overlapping unit for overlapping and joining the rubber sheet strips having different lengths to make an overlapped and joined strip; first holding members for holding a front end portion of a following overlapped and joined strip; second holding members for holding a rear end portion of a preceding overlapped and joined strip; support guides for movably supporting the first holding members relative to the second holding members; and an operating unit for moving the first holding members relative to the second holding members to butt-join the side surfaces of two successive overlapped and joined strips held respectively by the first holding members and the second holding members to generate a ply sheet. | 09-18-2008 |
