PURPOSE:To mold efficiently a tire, by applying the surfaces of a turnup bladder and a drum bladder of a tire molder with an organic halogen compound that can prevent unvulcanized rubber that will be vulcanized on said surfaces from adhering on said surfaces. CONSTITUTION:The surfaces of the drum bladder, the turnup bladder and an expand drum cover attached to the tire molder are coated with an organic halogen compound (e.g. N-bromosuccimide, trichloroisocyanuric acid, diisocynuric acid and dichlorodimethylhydatoin). Thus the unvulcanized rubber is prevented from adhering to the accessories of the tire molder, and deformation or failure of joining of the rubber would not occur. |
