PRODUCTION METHOD OF COVER FOR MOLD CLEANING |
摘要 |
An object of the present invention is to provide a production method of a cover for mold cleaning which can clean a mold without removing the mold from a vulcanizer and is excellent in a mold cleaning effect while maintaining productivity. The production method of a cover for mold cleaning is produced by applying an unvulcanized rubber composition on an outer periphery of a raw cover, the method comprising a rubber strip winding step of winding a rubber strip consisting of the unvulcanized rubber composition from side wall portions to tread shoulder portions of a raw cover, and a plate-like rubber material winding step of applying a plate-like rubber material consisting of the unvulcanized rubber composition on a tread center portion of the raw cover, wherein a gauge of the rubber composition after vulcanization of the cover is not less than 1.0 mm. |

1. A production method of a cover for mold cleaning produced by applying an unvulcanized rubber composition for mold cleaning on an outer periphery of a raw cover, the method comprising
a rubber strip winding step of applying a rubber strip by circumferentially and spirally overlapping and winding a long narrow rubber strip consisting of the unvulcanized rubber composition for mold cleaning from side wall portions to tread shoulder portions of a raw cover, and a plate-like rubber material winding step of applying a rubber material by once-winding a wide plate-like rubber material consisting of the unvulcanized rubber composition for mold cleaning on a tread center portion of the raw cover, wherein a gauge of the rubber composition for mold cleaning after vulcanization of the cover for mold cleaning is not less than 1.0 mm. |
