Pneumatic tire and manufacturing method thereof
View Patent ↗A method for manufacturing a pneumatic tire, including the steps of intermittently crimping volume adjusting members on both side sections of a sheet inner liner material in a longitudinal direction thereof beforehand, winding the inner liner material on an outer peripheral side of a forming drum, winding a sheet carcass material on an outer peripheral side of the inner liner material, forming an unvulcanized tire containing the inner liner material and the carcass material, and vulcanizing the unvulcanized tire. The volume adjusting members are intermittently arranged in a tire circumferential direction between the inner liner material and the carcass material.
1. A method for manufacturing a pneumatic tire, comprising the steps of:
intermittently crimping volume adjusting members on both side sections of a sheet inner liner material in a longitudinal direction thereof beforehand;
winding the inner liner material on an outer peripheral side of a forming drum;
winding a sheet carcass material on an outer peripheral side of the inner liner material;
forming an unvulcanized tire containing the inner liner material and the carcass material; and
vulcanizing the unvulcanized tire,
wherein the volume adjusting members are intermittently arranged in a tire circumferential direction between the inner material and the carcass material.
2. The method for manufacturing a pneumatic tire according to claim 1 , wherein the volume adjusting members are made of rubber compositions and set in a range from 1 mm to 10 mm in thickness.
3. The method for manufacturing a pneumatic tire according to claim 1 , wherein the volume adjusting members are arranged at equal intervals in the tire circumferential direction.
