するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for determining the quality of a bladder, and more specifically, the present invention relates to a method and apparatus for determining the quality of a bladder, and more specifically, to detect deflection (distortion) in the circumferential direction and/or radial direction when a vulcanized bladder is inflated. The present invention relates to a method and apparatus for determining the quality of a bladder, which can also determine the quality of the bladder while measuring the quality of the bladder.
従来からブラダ−は、加硫工程において多く用いられて
いる。Bladders have traditionally been widely used in vulcanization processes.

る。Therefore, the deflection in the circumferential direction and/or radial direction that occurs when the bladder is inflated, or the quality of the prong weld, is an important factor in improving tire quality as it affects the quality of the uniformity of the tire after direct molding. It is said that

にそのユニフォーミティ−を悪化せしめるのである。In other words, the wall thickness distribution state of the bladder after vulcanization is
It greatly affects the shape when inflated. In other words, if there are thin or thick parts, the bulge will be different and the overall shape will not be the same. Therefore, when a tire is vulcanized using such a bladder, the quality of the product tire, especially its uniformity, is deteriorated.

図及び第4図に示すブラダ−の肉厚とユニフォーミティ
−との関係を示す実験結果からも明らかである。The third point is that the quality of the bladder wall thickness distribution influences the quality of the uniformity of the product tire.
This is clear from the experimental results showing the relationship between the bladder wall thickness and uniformity shown in FIG. 4 and FIG.

の良否を判定している。However, in the past, there was no means to directly determine the circumferential and/or radial deflection of the bladder during inflation, or the quality of the fringe profile. By doing so, the wall thickness distribution in the circumferential direction and the radial direction is grasped, and from this wall thickness distribution state, the shape of the bladder when it is inflated is determined, and its quality is judged.

問題があるのが現状である。In this way, conventionally, the shape of the bladder in the dynamic state of inflated state was indirectly inferred from the state of the bladder's wall thickness distribution, in other words, from the static state to the dynamic state of the inflated state. Currently, there are many problems, such as not only good results are not always obtained, but also a lot of time is required for measurement and judgment, and the bladder used for measurement cannot be used again.
