| 156398000 | Means operating on the bead portion of the tire | 10 |
| 20080202690 | Bead lock Arrangement - This invention relates to a bead lock arrangement for use in tyre building equipment, and to tyre building equipment utilising such a bead lock arrangement. A bead lock assembly is disclosed comprising first and second parallel, coaxial, axially spaced bead lock arrangements ( | 08-28-2008 |
| 20080264570 | Tyre Drum Assembly Including Turn-Up Mechanism for Building an Unvulcanized Tyre - Assembly comprising a tyre drum ( | 10-30-2008 |
| 20090314436 | BEAD SUPPLY SYSTEM IN TIRE BUILDING PROCESS - The invention provides a bead supply system which stocks annular beads without bringing the beads into contact with each other and supplies the beads to a building machine in steps where bead setting and turning up are carried out in tire building and includes a bead stocking unit ( | 12-24-2009 |
| 20130008611 | Multi-Piece Sealing Sleeve - A multi-piece sealing sleeve is disclosed. The multi-piece sealing sleeve includes annular first and second layers of a substantially air-impermeable material. The first layer has an inner edge sized to surround a base portion of the tire shaping drum. An outer edge of the first layer extends radially outwardly to overlie at least a portion of a radially expandable and collapsible structure defined by the tire shaping drum. The second layer is sized to overlie and establish sealing engagement with at least a portion of the first layer and a bead seat defined by the radially expandable and collapsible structure of the tire shaping drum. The first and second layers cooperate to establish a substantially airtight seal between the tire shaping drum base portion and the bead seat. | 01-10-2013 |
| 20140174665 | PROCESS AND APPARATUS FOR PRODUCING PNEUMATIC TYRES - Along a building line, a green tyre is built on a rigid toroidal support having an outer surface substantially conforming in shape to an inner surface of the green tyre. The green tyre is then transferred to a bead moulding and prevulcanisation station where each bead of the tyre is moulded by tightening it between a surface portion of the toroidal support and an annular clamping surface carried by a removable tightening flange. The tightened beads are prevulcanised through a heat supply by means of electric resistors integrated into the tightening flanges. The tyre with the prevulcanised and tightened beads is transferred into a moulding cavity having an inner wall of a shape substantially conforming to that of the outer surface of the moulded tyre, to carry out moulding of the tyre and complete vulcanisation of same. | 06-26-2014 |
| 20160059503 | PLY MAKING APPARATUS FOR TIRE MANUFACTURING - A ply making apparatus for making a tire carcass is described. The ply making apparatus includes a support frame, and a rotatable member mounted to the support frame. The rotatable member further includes a spool mechanism for winding a strip of ply. A first and second bead support holder is located adjacent each other, wherein a first bead support holder supports a first bead in parallel relationship and axial alignment with respect to a second bead held by a second bead holder, wherein the rotatable member is positionable inside each bead. | 03-03-2016 |
| 156400000 | Means folding carcass fabric about a bead | 3 |
| 20130306243 | APPARATUS FOR PRODUCING PNEUMATIC TYRES - An apparatus for producing a pneumatic tyre has a building unit designed to form a green tyre having a pair of beads. Each of the pair of beads is defined along a respective inner circumferential edge of the green tyre. The apparatus further includes bead moulding devices to tighten each bead between two axially opposite clamping surfaces. A moulding unit of the green tyre has a moulding cavity with an inner wall substantially conforming in shape to an outer surface of a moulded tyre. The apparatus further includes devices for vulcanising the green tyre, and actuating devices for transferring the green tyre together with the bead moulding devices into the moulding cavity. | 11-21-2013 |
| 156402000 | Disc or roller type | 2 |
| 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 |
| 20130139971 | DEVICE FOR TURNING UP BODY PLY - A body ply turn-up device for turning up at least one width-end portion of a body ply expanded into a toroidal shape includes a plurality of arm components movable in the axial direction of an operating shaft and pivotable radially of the operating shaft. Guide members are respectively supported on an end portion of each arm component and coil springs are interposed in respective spaces between guide members. Elastic members respectively cover the outer surfaces of the coil springs for performing pressing at spaces between spiral wire portions thereof when the arm components are pivoted radially outward of the operating shaft. Alternatively, the guide portions include portions which are smaller than the inner diameter of the coil spring and which extend to positions nearly touching each other at a center in a lengthwise direction of each coil spring in a state that the arm components are contracted. | 06-06-2013 |
| 156403000 | Means placing bead ring on tire carcass | 1 |
| 20090071606 | Alignment system for positioning tire beads onto a tire core side wall - A combination of a plurality of equal spaced permanent magnets that are each fitted into a magnet cup formed into a cavity mold side outer surface that is immediately opposite to a slot formed around an outer edge of the inner surface of the cavity mold side, leaving a thin section of the cavity mold side material that separates the respective bottoms of the magnet cups from the bottom of the slot. The slot receives a tire bead whereover a tire plies is folded and is held in that slot by the attractive force provided by the permanent magnets, and pins are fitted at spaced intervals into, to extend outwardly from, the slot bottom surface to engage and center the tire bead in the slot. | 03-19-2009 |
