The present invention relates to a method and apparatus for joining end portions of tire constituent members that can be joined accurately and automatically.
従来、タイヤ成形工程において、タイヤ成形ドラム上で
タイヤトレッド等のタイヤ帯状構成材料を貼付ける作業
が行なわれている。BACKGROUND ART Conventionally, in a tire molding process, a tire band-shaped constituent material such as a tire tread is pasted on a tire molding drum.
しかしながら、タイヤトレッドは断面略台形状で中央部
の肉厚は厚く、裾部において薄肉となっているため、円
柱状の成形ドラムに貼付けた場合、定尺切断されている
タイヤトレ・ンドの始端部中央と終端部中央は突合せ接
合は可能であるが、両側縁部は端部が円弧状に湾曲した
り、シュリンクして端末部間に間隙ができてしまう。However, since the tire tread has a substantially trapezoidal cross-section and is thick at the center and thin at the hem, when it is pasted on a cylindrical forming drum, the starting end of the tire tread, which has been cut to length, Although it is possible to butt-join the center and the center of the end portion, the end portions of both side edges may curve into an arc shape or shrink, resulting in a gap between the end portions.
従って作業員が湾曲したりシュリンクした端末部を持っ
て引き寄せ、タイヤトレッドの端末部同志の突合せ接合
を行なってい・た。Therefore, workers had to hold the curved or shrunk end portions and pull them together to butt join the end portions of the tire treads together.
しかしながら、作業員の手作業が常に必要となるために
、作業能率が極めて悪く、生産性の向上を図ることがで
きないばかりか、精度の高い突合せ接合をすることがで
きなかった。However, since manual work by workers is always required, work efficiency is extremely low, and not only is it impossible to improve productivity, but also it is impossible to perform highly accurate butt joints.
（発明が解決しようとする問題点〕
そこで、係る問題を解決するためタイヤ成形ドラム上で
帯状材料の始端部と終端部とを自動的に突合せ接合する
タイヤ構成部材の成形方法及び装置が従来提案されてい
る（例えば、特開昭６２−２３６７２８号公報、特開昭
６０−７９９３８号公報）。(Problems to be Solved by the Invention) Therefore, in order to solve this problem, a method and an apparatus for forming a tire component have been conventionally proposed in which the starting end and the end end of a strip material are automatically butted and joined on a tire forming drum. (For example, JP-A-62-236728, JP-A-60-79938).

に、精度良く、しかも自動的に突合せ接合することは非
常に難かしいという問題があった。However, Japanese Patent Application Laid-Open No. 62-236728 discloses a method in which the central part of the end of a strip-like material is crimped and fixed with a crimping member, and then both edges of the tip are gripped with hands, stretched toward the end, and butt-joined. In the case of this method, it is possible to butt join the central part, but to butt join both edges of the starting end side and both edges of the ending end of the strip material, it is necessary to sandwich both the starting end side and the ending end side. There is a problem in that it is very difficult to butt-join with high accuracy and automatically because the joints are not joined in a state where the parts are in the same state.
