ABSTRACT:
An inflatable shaping bag or diaphragm for a tire building or shaping former. The bag is based on an elastomeric sheet radially expansible but has high lateral bending stiffness in part of its width owing to the presence of at least one pair of reinforcements of inextensible reinforcing elements, each element lying in a plane containing the axis of the bag. The reinforcement can consist, for example, of two layers of parallel steel cords, spaced apart by a layer of rubber.
