る手作業に依存しているのが実情である。In the retreaded tire manufacturing process, during full remolding, where the sidewall is reattached and retreaded, the old rubber layer is puffed to remove the damaged area, and a new rubber sheet for retreading is pasted on top. In addition to being easy to stretch (and wrinkle easily), the circumferential length of the top and bottom of the sidewall is different, making the pasting process difficult to automate due to the difficulty of adjusting the tensile strength and relying exclusively on manual work by skilled workers. The reality is that it is.

生む原因となり問題となっている。(Problems to be Solved by the Invention) The work of pasting sidewall rubber in the tire retreading process involves removing old rubber by puffing or cutting it and then pasting new rubber. Therefore, the sidewall portion has a three-dimensional curved surface. On the other hand, the new rubber sheet for the wall under the wall for renewal is a long strip of unvulcanized rubber about 1 inch thick.
Because it is flexible and easy to stretch, and is highly adhesive on both sides, this sidewall rubber sheet is meanderingly applied to the entire sidewall portion of a retreading tire with a three-dimensional curved surface as described above. To prevent wrinkles, and to prevent the thin rubber sheet that will become the new sidewall rubber from stretching too much.
Automation of the process is considered difficult, as it is necessary to delicately adjust the degree of stretching and align the center while pasting, and even now it is still pasted by hand by workers with long experience and skilled techniques. . For this reason, not only is it difficult to expect an improvement in work efficiency, but there are also variations in the accuracy of each worker's work and variations in the tension adjustment applied to the rubber sheet, which causes variations in product quality and is a problem.
本発明は、手作業による問題を解決するためになされた

ドウオール用ゴムシートの自動貼付は装置を提案するこ
とを目的とするものである。The present invention was made in order to solve the problem of manual work, and it is an object of the present invention to propose an extremely effective and suitable automatic pasting device for sidewall rubber sheets that can automate the above-mentioned work.
そしてその特徴とするところは、サイドウオールの周長

能にすることを特徴としている。さらにゴムシートを台
タイヤのサイドウオールに圧着するためのロール表面は
スポンジ製として圧着力の均一分散を図っている。The feature is that in order to eliminate the difference in the circumferential length of the sidewall, instead of thinking about attaching a rubber sheet along the circumference, a pressure roller is operated in a radial line from the center of the tire, and the rubber sheet is attached on the center line. Insert it and make a "point" crimping, and have them perform this continuous operation one after another. That is, by performing pasting similar to straight-line pasting, the generation of wrinkles due to sagging of the rubber sheet can be minimized, and automatic pasting can be performed. Furthermore, the surface of the roll used to press the rubber sheet to the sidewall of the base tire is made of sponge to ensure even distribution of the pressing force.
以下本発明のサイドウオールゴムの自動貼付は装置の一
実施例を図面に基づき説明する。An embodiment of the apparatus for automatically pasting sidewall rubber according to the present invention will be described below with reference to the drawings.

しサイドウオールゴムシートの貼付けが始まる。In the figure, the sidewall rubber sheet E to be pasted from let-off 1 is wound into a roll, and while applying a brake B to the core of this roll, the sheet 1 is pasted onto the pasting part 2.
- Supply E. For pasting, use the upper and lower guide rollers H in part 2.
The sheet E is centered and sent to the pressure roller C. The pressure roller is already pressed against the base tire, and the rubber sheet I is inserted between the base tire and the roller and is inserted by rotation of the tire, and is pressed against the tire to begin pasting the sidewall rubber sheet.

た場合、補助ローラＤによりその部分を仕上げる。FIG. 2 shows how the rubber sheet is attached. The radially pasted rubber seals 1-A are repeatedly and continuously operated in a straight line by the main pressure roller C, and the pasting is done in a posture close to straight pasting, thereby minimizing wrinkles and making automatic pasting possible. In addition, if the main pressure roller C fails to bond, the auxiliary roller D finishes that part.

する。Therefore, when attaching the rubber sheet for the sidewall, adjust the tension inside by applying a brake to the shaft around which the rubber sheet is wrapped so that the tension is uniform throughout the entire length and in the length direction. It is possible to supply the rubber sheet while automatically forming it into an approximate shape, and the attached rubber sheet is moved and pressed in the radial direction of the tire by the main pressure roller C, which has the effect of eliminating sagging parts such as wrinkles.

果を発揮している。As shown above, when the sidewall rubber of a retreaded tire is replaced with a new rubber sheet, when the rubber sheet is supplied and pasted on the side part of the base tire that has been inflated by filling with air internal pressure, the present invention can be applied to the same way as described above. Regardless of manual labor,
The supplied sidewall rubber sheet can be automatically and continuously supplied in the radial direction in a shape that approximates the three-dimensional shape of the side portion of the base tire. As a result, it has become possible to uniformize the work and significantly improve work efficiency, which was impossible to achieve with conventional manual methods, as well as improve the quality of retreaded tires and improve product reliability. It is also effective in significantly reducing manufacturing costs.
