BLADDER FOR TIRE VULCANIZATION AND METHOD FOR PRODUCING PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a bladder for tire vulcanization which can be smoothly peeled from the inner face of a vulcanized tire, can smoothly take out the vulcanized tire and can smoothly insert a tire to be vulcanized, and to provide a method for producing a pneumatic tire.SOLUTION: A plurality of thin wall parts A1 to A8 having a film thickness smaller than the peripheral thickness are disposed at intervals in the bladder circumferential direction at a bladder inner surface near an upper side clamp part 3a on at least one end of the peripheral edges of both ends of a cylindrical body part 2a within a range of the outer peripheral side from a part in which the upper side clamp part 3a is held by an upper side clamp holding part 5a.
