The present invention provides a method for producing a pneumatic tyre in which a noise damper in the form of at least one continuous ribbon for reducing cavity resonance in a tyre cavity is provided on the internal surface of a tyre on the inside in the radial direction of the tyre corresponding to the tyre tread, said method including the following stages: a stage in which a vulcanized and shaped tyre is provided; a stage in which a composition for forming the noise damper is mixed with a foaming agent to produce a liquid composition; a stage in which the tyre is rotated in an upright state by means of a tyre holding and rotation device, and the liquid composition is introduced onto the tyre internal surface by means of a device for introducing the liquid composition; a stage in which the relative positional relationship of the pneumatic tyre and the introduction implement in the axial direction of the tyre is varied while the liquid composition is introduced onto the tyre internal surface, and the liquid composition introduced onto the tyre internal surface is formed into a gel; and a stage in which the gelled liquid composition is foamed and dried. |
