Description

ABSTRACT:
A tire building machine has a dual bladder ply turn-up mechanism including radially inner and outer annular bladders mounted on a radially stepped annular support. Each bladder is fully contour molded and has imbedded in its radially inner wall a plurality of circumferentially spaced flanged inserts adapted for connecting and positioning the bladder on the support. Each bladder further includes position stabilizers in the form of inelastic cinch bands which include openings through which the inserts extend and the outer bladder may also include an annular girdle to improve bladder rolling characteristics. Also provided is a one-piece manifolded bladder support which includes a radially stepped cylindrical support surface for the bladders and internal porting means for bladder inflation.
