摘要： A radial tire carcass fabricated by a first stage process has bead portions which are placed over a pair of spaced-apart coaxial bead seats. The bead seats may be segmented radially expandable rings which are expanded by fluid pressure into engagement with the bead portions. The tire carcass is initially positioned on the drum with the bead seats at a spaced-apart distance so that upon expansion of the segments of the bead seats at a low pressure and axial movement apart of the bead seats the ply of the tire carcass is stretched and the bead portions moved into register on the bead seats. The fluid pressure expanding the segments of the bead seats is then increased to secure the bead portions on the bead seats at predetermined positions with a predetermined diameter. Annular sealing members may be mounted on the segments of the bead seats at the tire-supporting surfaces of the segments for compression upon application of high pressure. The sealing members may also have flaps for bridging the space between the bead portions of the tire and mounting rings for the segments of the bead seats so that the tire may be inflated after registration of the bead portions and while the bead seats are moved axially together for the application of the tread and belt ply.

摘要： Method and apparatus for building a cord or wire wound carcass for a closed torus tire. An endless flattened inflatable tube providing a liner for the carcass and coaxially spaced bead rings are placed on a support comprising a cylindrical array of rolls. The bead rings are spaced axially to control the length of each turn of cord or wire wound in the flattened oval path around them. A single wire or cord is wound in a flat oval orbit about the liner and bead rings by orbiting a spool along a track having two straight parallel portions, one inside, the other outside the bead rings and liner. The parallel track portions are connected at their ends by semi-circular track portions. No rigid core is required. After winding the cord or wire about the liner and bead rings, the liner is inflated and the bead rings are shifted axially toward each other to the axial spacing appropriate for the inflated tire in use.

摘要： A simple low cost building arbor having a wide range of axial length or bead set length variation. The arbor has no moving parts which are not of rubber or rubber-like material and is operable by air pressure alone. An expandable ring expands, by air pressure, to hold a bead ring in axial position and independently a turn-up bladder is expanded to turn a ply sleeve end about the bead ring. Operating air is conducted, in all axially selected positions in the range, not by tubing but by air transfer chambers connecting the bladder and a sleeve associated with the expandable ring with passage in the center shaft.The present invention relates to a building arbor for tires and like articles.The principal object of the invention is the provision of a simple, low cost building arbor actuable solely by fluid pressure to position an inextensible bead ring about a ply in cylindrical form on the arbor and to turn the ply ending about the bead ring. Broadly, the objects of the invention are accomplished in a building arbor comprising a center shaft having passages for conducting fluid, a pair of end rings axially slidable on the center shaft and having axially elongated annular air transfer chambers, the chambers being in air flow communication, respectively, with said passages and with a plurality of inflatable members affixed to each of the end rings, each of the members being expandable by fluid pressure in the respectively associated passage independently of another of said members in any selected axial position of the respectively associated end ring.Briefly, the objective of the invention is accomplished also by a building arbor having a fixed nonexpandable building surface and a pair of expandable beadseating rings located respectively at the axial ends of the building surface, said beadseating rings being mounted respectively in unitary assemblies each including a primary ring, and means for adjustably fixing the axial distance between the two end rings comprising a pair of semi-cylindrical shells of selected axial length axially abutting each end ring and supported coaxially of the arbor by said end rings.To acquaint persons skilled in the most closely related arts certain preferred embodiments illustrating the best mode now contemplated of putting the invention in practice are described hereinbelow making reference to the attached drawings forming a part of the description and of this specification.

摘要： Method and apparatus for assembling a tire carcass comprising a precarcass band and a pair of inextensible bead rings. The band is built and consolidated on a form having a rigid cylindrical surface. The band includes at least one cord or wire-reinforced ply and one or more tire liners of a rubbery gum, and may include additional tire components, in particular the components which will form the sidewalls of the tire. The band is removed from its building form and then moved axially freely over a shaping apparatus. An axially narrow central part of the band is expanded sufficiently to resist axial displacement of the band, which is then spread and smoothed outward from its central part by expanding and then moving outwardly a pair of expandable spreading elements. Following the spreading operation, end regions of the band are expanded to seat the prepositioned inextensible bead rings, after which the bead rings are moved axially toward each other and the band therebetween is expanded by air pressure into engagement with a circumferentially restricting ring or belt. With the carcass so expanded, the band endings are turned outwardly about the bead rings by turnup bladders while a pair of annular inner support bladders exert circumferentially uniform axially outward counter-force to squeeze the respective beads.

摘要： An apex is cohered to the bead wire bundle or core to form a unitary bead assembly. The core is supported on a rigid continuous planar surface. The apex strip in endless form is supported on the uninflated inflatable cylindrical surface of a turn-up bladder arrangement. Inflation of the bladder arrangement turns or rolls the apex angularly outward to surround the bead core and into an appropriate radial orientation and shape. The bladder action is found to cohere the apex-core so strongly together that conventional roller stitching is not required.
