    摘要: Drum for manufacturing radial-carcass tires, characterized in that it comprises means acting in synchronism for transforming a plane cylindrical surface, on which the rubber layers are laid together with the radial plies and the bead wires, into a toroidal surface by producing a geometrical preformation both in development and in section, and by a positive turning of the fabric and layers after shaping same.

    摘要: A TIRE BUILDING MACHINE HAVING AN EXPANDABLE DRUM WITH SEPARATE CROWN AND SHOULDER DRIVES FOR CONTROLLING THE MOVEMENT OF THE CROWN AND SHOULDER PORTIONS TO SHAPE THE PLIES TO THE FULL TIRE SHAPE AND MAINTAIN UNIFORM SPACING OF THE CORDS. THE OUTBOARD END OF THE DRUM IS SUPPORTED BY AND LATCHED TO A TAILSTOCK TUBE FOR THE TRANSFER OF AXIAL FORCES FROM THE TAILSTOCK TO THE DRUM DURING THE BUILDING OPERATION. AXIAL MOVEMENT OF THE DRUM SHOULDERS IS ADJUSTABLY CONTROLLED BY INTERCONNECTED ADJUSTABLE STOPS MOUNTED ON THE TAILSTOCK AND MAIN HOUSING WITH PISTON CYLINDER ASSEMBLIES RESISTING MOVEMENT OF THE SHOULDERS IN DIFFERENT DIRECTIONS TO CONTROL RADIAL EXPANSION AND CONTRACTIONN OF THE SHOULDERS DURING THE BUILDING OPERATION IN COOPERATION WITH THE SHOULDER DRIVE.

    摘要: Apparatus for building pneumatic tires embodying an intermediate assembly and an end assembly at each end of the intermediate assembly for supporting tire carcass material initially in the form of a tubular cylinder, each of the end assemblies embodying bead shoulder forming means for displacing the tire carcass material radially outwardly to form bead shoulders against bead setter means position and hold tire beads against axial movement toward each other and in concentric outwardly spaced relation with respect to the carcass material, ply turnup means for encasing the tire beads at the bead shoulders, and in which the intermediate supporting members movable radially and circumferentially relative to each other to form the tire carcass material into substantially torus configuration upon releasing of the tire beads by the bead shoulder-forming means for axial movement of the tire beads axially toward each other. Method of building pneumatic tires in which tire carcass material is initially formed into a tubular cylinder after which radially outwardly extending tire bead shoulders are then formed inwardly of the ends of the tubular cylinder, and against which tire beads are held against axial movement toward each other arm in fixed concentric outwardly spaced relation, followed by encasing major portions of the tire beads by displacing end portions of the tire carcass material while the tire beads are held concentrically against the bead shoulders, concentrically freeing the tire beads and fully encasing the same by turning up the remaining end portions of the tire carcass material while the tire beads are engaged with the tire bead shoulders, and then predeterminately releasing the encased tire beads for axial movement toward each other in forming the tire carcass material into substantially torus configuration.
