Method for producing pneumatic tire

摘要

A method for producing a pneumatic tire according to the present invention can use existing facilities without change and does not make the spliced parts of an inner liner easily opened even if the tire is produced with use of an inner liner having a low adhesion.;In a method for producing a pneumatic tire having steps of winding an inner liner 8′ around a tire building drum 21 to form a cylindrical body, the cylindrical body is formed by attaching a winding-starting end 8′a of the inner liner 8′ to the building drum 21 via an uncured tacky member 9′, winding the inner liner 8′ attached to the building drum 21 around the building drum21, and splicing a winding-finishing end side of the wound inner liner 8′ with the winding-starting end 8′a of the inner liner 8′ via the uncured tacky member 9′.

1. A method for producing a pneumatic tire having steps of winding an inner liner around a tire building drum to form a cylindrical body, the steps comprising:
attaching a winding-starting end of the inner liner directly to the building drum using an uncured tacky member; winding the inner liner attached to the building drum around the building drum; splicing a winding-finishing end of the wound inner liner with the winding-starting end of the inner liner via the uncured tacky member to form the cylindrical body, body; applying a tying rubber layer to the inner liner; and applying an unvulcanized carcass ply to the tying rubber layer, wherein the uncured tacky member is an uncured tape-shaped tacky member having an adhesive property on both surfaces thereof enabling adhesion to the winding-starting and winding-finishing ends of the inner liner and to the building drum, the attaching step comprising putting the winding-starting end of the inner liner on the building drum, and attaching the winding-starting end of the inner liner to the building drum via the uncured tape-shaped tacky member applied to the winding-starting end of the inner liner, the winding step comprising winding the inner liner attached to the building drum fully around the building drum, the splicing step comprising applying a winding-finishing end of the wound inner liner onto the uncured tape-shaped tacky member, wherein by placing the winding-starting end of the inner liner around the building drum, the uncured tape-shaped tacky member is attached to an outer surface in a tire radial direction of the winding-starting end of the inner liner, wherein the carcass ply has reinforcing cords embedded therein, and the inner liner lacks reinforcing cords, and wherein the adhesive property of the uncured tacky member is of sufficient strength to hold the winding-starting end on the building drum without suction from the building drum.
