製造方法を提案した。 In a separate patent application related to a method for manufacturing retreaded tires, the applicant proposed a method for improving tire uniformity by improving static unbalance of tires, which causes adverse effects on vehicle performance such as steering wheel shake. The objective is to determine the lightest point (the lightest point due to uneven rubber content) of a tire that has been buffed by removing worn treads and breakers, and repairing depressions on the buffed surface.
The process of detecting the unbalance mark and attaching an unbalance mark indicating the position of the lightest point to the base tire, and wrapping the tread around the base tire using the unbalance mark (lightest point) position as the starting point for wrapping the unvulcanized tread. The amount of tread rubber at the lightest point position can be adjusted by positioning the cut end, where the shrink width after wrapping and extrusion increases the tread width compared to other parts, and therefore the amount of rubber is larger than other parts, at the unbalance mark point. We proposed a method for producing retreaded tires whose main steps are:

異種サイズのリムを多数個用意せねばならないこ
と、リムへのタイヤの着脱作業や枠体へのリムの
掛替作業に多くの労力や手間が必要であること等
の問題がある。 In this manufacturing method, as a device for detecting the lightest point of the base tire, for example,
No. (title of the invention "Method for measuring wheel balance"),
It is conceivable to use the "freely rotatable tire rim" disclosed in Japanese Patent Publication No. 49-357105 (title of the invention "Wheel balance detector").
When using such tire rims, the rims are expensive, it is necessary to prepare multiple rims of different sizes for different tire rim diameters, and the work of attaching and detaching the tire to the rim and the frame body are difficult. There are problems such as the need for a lot of effort and effort to replace the rim.
このため、実開昭54−104465号（考案の名称
「タイヤ成形装置におけるバンド挿入補助プー
リ」）に開示されている。“自由回転可能な１本の
直プーリ”を利用することが考えられるが、１本
の直プーリに台タイヤを掛け下げて回転させるだ
けでは最軽点の検出はきわめて困難である。 For this reason, it is disclosed in Japanese Utility Model Application Publication No. 54-104465 (name of the invention: "Band insertion assisting pulley in tire forming device"). It is conceivable to use "a single straight pulley that can freely rotate," but it is extremely difficult to detect the lightest point just by hanging a stand tire on a single straight pulley and rotating it.
そこで、実開昭54−7267号（考案の名称「生タ

能な２本の直ロール”を利用することが考えられ
るが、直ロールであるが故に、回転中に台タイヤ
が横振れするので回転が不安定になり最軽点の検
出もばらつくという、この種最軽点検出用装置と
して利用するには致命的な欠点が存する。 Therefore, it is possible to use "two straight rolls that can rotate freely" disclosed in Utility Model Application Publication No. 54-7267 (name of the invention "Raw Tire Rotating Stand"), but it is not possible to use straight rolls. Therefore, there is a fatal drawback in using this type of device for detecting the lightest point because the base tire vibrates sideways during rotation, making the rotation unstable and causing variations in the detection of the lightest point.

に提供するものである。 The present invention was devised in view of the problems of the former two conventional devices and the problems of using the latter two devices. The purpose of the present invention is to provide a new retreaded tire manufacturing auxiliary device in which rehanging work is extremely easy, the rotation of the stand tire is stable, and the detection of the lightest point is even easier.
以下、本考案を図面を参照しつつ詳細に説明す

材質は例えば鉄製である。 FIG. 1 is a schematic side view showing a device according to an embodiment of the present invention, and FIG. 2 is a partially vertical front view of FIG. 1.
In the diagram and FIG. 3, which is a cross-sectional view of the free roller, 1 is a frame body, and 2, 2 are free rollers, and the free rollers 2, 2 are two on each side of the frame 1, and are freely rotatable in parallel. , both are at the same height and are cantilevered through bearings 7 so that the rotating shaft 6 is in a horizontal state, and as shown in FIG. (in this case, the height h of the maximum ampullae is, for example, 5 mm, and the total length l is, for example, 500 mm),
The material is, for example, iron.

易に行うことができるのである。 When the free rollers 2, 2 have the curved surface 8 in this way, the bead portion of the base tire 3 comes into point contact with the free rollers 2, 2 only at the bead toe portions 5, 5, so that The platform tire 3 that rotates produces stable rotation without sideways vibration, which not only makes it easier to detect the lightest point, but also makes it easier to detect the lightest point.
Repair work on the buffing surface, which is carried out by suspending and rotating the stand tire 3 on the free rollers 2, 2, can be carried out even more easily.
本考案の装置の使用方法は次の通りである。 The method of using the device of the present invention is as follows.

ローラー２から取り外し、次工程に移す。 The base tire 3 is hung so that the bead toe portions 5, 5 of the bead portions are in contact with the two free rollers 2 supported cantilevered on the frame 1, and while rotating the base tire 3 by hand, Repair through holes etc. Then, the repaired base tire 3 is rotated by hand, and when the rotation has stopped naturally, a rubber yoke is used to make a small indentation on the sidewall portions 9, 9 corresponding to the highest position (i.e., the lightest point) of the base tire 2. Attach balance mark 4. The stand tire 3 is removed from the free roller 2 and moved to the next process.
