ABSTRACT:
A shoulder bladder used to make green tires has an inflatable portion including an inner-rubber member encased in body-ply and cover-rubber layers. Steel cords fixedly mounted relative to and projecting away from the cover-rubber layer have a first edge close to a lower corner of the uninflated bladder and approximately aligned with aligned ends of the cover-rubber and body ply layers. A cord-rubber composition extends (a) from and is adhered to a bottom portion of the cover-rubber layer, (b) around and adhered to the steel cords, (c) around two aligned corners on lower and upper surfaces of the bladder, and (d) along a top surface of the cover-rubber layer. The cord-rubber composition is adhered to the cover-rubber layer where the cord-rubber composition extends from the steel cord to the top surface of the cover-rubber layer.
