ABSTRACT:
A tire ply end turn-up device comprising an inflatable first rubbery polymer bladder body, a second non-stick rubbery polymer layer on at least a portion of the surface of the bladder body, and fabric between the bladder body and the non-stick surface. The ply turn-up bladder is made by forming an uncured rubbery polymer bladder body, forming a composite of fabric calendared on one side with an uncured non-stick rubbery polymer and on the other with a rubbery polymer that will bond with the bladder body upon curing, applying the composite to at least a portion of the bladder body, and curing the bladder body and composite to form an integral turn-up bladder with a non-stick rubber surface. A rubbery polymer that will bond with the uncured bladder body upon curing is used on the fabric side that contacts the bladder body.
