ABSTRACT:
A multiple-ply tire carcass building apparatus is described. A collapsible/expandable tire band applier is used to sequentially apply a plurality of cylindrical tire bands onto a collapsible tire building drum to form the multiple-ply tire carcass. An air nozzle or a plurality of air jets are longitudinally extend over a portion of the longitudinal surface of the tire building drum and any tire bands thereon and is spatially separated therefrom for facilitating the placing of the tire band onto the tire building drum. Preferably, a selectively positionable light sensing means carried by an expandable with the band applier is utilized to automatically and accurately provide the band applier with an outer diameter slightly less to slightly greater than that of the tire building drum and any tire band thereon so that the tire band can be displaced from the band applier onto the tire building drum. The light sensing means is also selectively positionable to provide the leading end of the air nozzle with an initial clearance from the tire building drum during the positioning of the band applier in a working relationship with the tire building drum and provide the air nozzle or air jets with the desired spatial separation from the surface of the drum and any tire bands already thereon.
