A METHOD FOR MANUFACTURING A SEALANT LAYER TO A PNEUMATIC TIRE

A method for manufacturing a self-sealing sealant layer (10) to a pneumatic tire (1) for a vehicle, wherein the vulcanized tire (1) is positioned to a tire rotator device (40) such that the rotational axis (12) of the tire is horizontal and the tire (1) is rotated around said horizontal axis (12), a...

Beschreibung
Zusammenfassung:	A method for manufacturing a self-sealing sealant layer (10) to a pneumatic tire (1) for a vehicle, wherein the vulcanized tire (1) is positioned to a tire rotator device (40) such that the rotational axis (12) of the tire is horizontal and the tire (1) is rotated around said horizontal axis (12), a sealant material is heated to a temperature of 70 - 200 °C, the adhesive sealant strip material (105) is extruded downwards on to an innerliner (11) of the tire by an applicator head (5), the applicator head (5) is extruding the strip material, the applicator head (5) is moved in a traverse direction so that the strips (105) form a substantially continuous sealant layer (10) on a puncture resistivity area (20), a number of revolves of the tire (1) is adapted to a width of the strip (105) so that tire (1) is rotated to form the sealant layer (10). The invention concerns also a corresponding tire.
