TIRE BREAKER BELT BUILDING APPARATUS AND METHOD OF ADJUSTING SAME Abstract of the Disclosure The building surface diameter of a tire belt building drum is made steplessly variable for improved control of the diameter of a tire breaker belt. Guide legs extending radially inward from each of the segment bars which form the drum surface are formed as hooks, of J-shape, semi-circular in profile. The short upright of the J-shape abuts a conical surface of an annular body having screw threads mating with a screw-threaded hub fixed on the drum so that the conical surface can be displaced coaxially thereby adjusting the radial limit of the outward movement of the legs and segment bars. The hub member carries a circumferential track near the edge of the drum building surface. A guide wheel mounted on the delivery end of a conventional ply server tray or conveyor rolls on the track while ply stock is being fed onto the drum to improve the placement of ply stock in the breaker belt. 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.
