Abstract

Abstract A tire building machine of the second-stage type includes a housing with a main shaft journaled in and projecting from the housing in cantilever fashion. Distal and proximal flanges are mounted on the shaft for axial movement toward and away from each other and for rotation with the shaft, each flange being supported on the shaft by an elongated sliding sleeve, the distal flange being secured to its sleeve by a readily removable nose piece supporting the flange axially offset from the distal end of its sleeve, the sleeve for the distal flange being slidably supported by an elongated bushing at its proximal end only while the sleeve for the proximal flange is slidably supported by bushings at each end, one riding on the shaft while the other rides on the sleeve for the distal flange. Each sleeve is driven for axial movement from its inner end by a screw shaft journaled in the main shaft and having identical but opposite hand threaded sections both in the cantilevered portion of the shaft and outside the housing. The simplified construction permits both flanges readily to be removed and replaced by flanges of a different size. The construction of the shaft and flange supporting sleeves is such that no outboard support is required for the shaft with deflection and run-out being minimized.
