Abstract
A method of making a belt overlay structure for a pneumatic tire is provided. In the method, a belt structure is wrapped circumferentially around a cylinder which is secured to a rotatable shaft, and a ribbon comprising an elastomeric substance containing side-by-side textile cords extending longitudinally in the ribbon is provided on a let-off means. A first end of the ribbon is adhered to the outermost belt ply in close proximity to the axial center line of the belt structure, and the cylinder is rotated while ribbon is supplied from the let-off device. The let-off device first traverses to a first lateral edge of the belt structure where the lateral movement of the let-off means stops while the cylinder continues to rotate and the let-off means continues to supply ribbon. The let-off means is then caused to supply more ribbon while traversing laterally to a second lateral edge of the belt structure and stopping at the second lateral edge while the cylinder continues to rotate and the let-off device continues to supply ribbon. The let-off means then traverses to the axial centerline of the belt structure, and the cylinder and the let-off means are then stopped, the ribbon cut and a second end of the ribbon is adhered to the underlying ribbon.
