ABSTRACT:
A method for mounting or installing on a tire building machine an annular inflatable bladder for use in turning or folding the edge of a ply disposed around the building drum about a bead ring or a fold line. The method employs a collapsible cylindrical form which can comprise a split cylindrical ring or a cylindrical array of strips placed inside the annular bladder, which form is expanded to permit its movement axially over the drum. The method enables the bladders to be placed or replaced on the drum without dismantling the drum and particularly without requiring that the drum be removed from the shaft on which it is mounted thereby reducing the time required for installation of the bladder and the out-of-service time of the building drum.
