BUILDING ARBOR FOR TIRES AND LIKE ARTICLES HAVING INEXTENSIBLE BEAD RINGS Abstract of the Disclosure 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 foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
