Patent ID: 7195683

Claim:
A method of manufacturing a self-sealing tire having a pneumatic tire and a puncture sealing layer disposed over a whole tire inner wall surface from one shoulder portion to the other shoulder portion of the pneumatic tire, comprising the steps of: press attaching a first adhesive discharged from a discharge port of a first adhesive extruder by means of rollers onto a radially outer surface of a rotating annular sponge layer around an entire circumference of the annular sponge layer consecutively, thereby impregnating the annular sponge layer with the first adhesive from a radially outer surface of the annular sponge layer to form an adhesive impregnated sponge layer with the first adhesive not exposed on a radially inner surface of the annular sponge layer but is exposed on the radially outer surface of the annular sponge layer; press attaching a second adhesive discharged from a discharge port of a second adhesive extruder by means of rollers onto a radially outer surface of the adhesive impregnated sponge layer rotating around an entire circumference of the adhesive impregnated sponge layer consecutively, thereby forming a bonding layer made of the second adhesive on the radially outer surface of the adhesive impregnated sponge layer to form a puncture sealing layer; compressing the puncture sealing layer; and attaching the compressed puncture sealing layer onto the tire inner wall surface via the bonding layer, wherein a recovery force of the annular sponge layer is adapted to attach the puncture sealing layer onto the tire inner wall surface.
