PROBLEM TO BE SOLVED: To provide a roll press machine provided with a wrinkle-preventing device which suppresses the occurrence of wrinkles produced by a roll press operation on a coating part and an uncoating part of an electrode plate.SOLUTION: A wrinkle-preventing device pushes an operation roll of which the diameter is smaller than a diameter of a press roll against the press roll, the operation roll is supported by a bearing frame via a reinforcing roll and an uncoating part can be drawn with an even pressing force. Further, an end part roller is arranged on a shaft end part of the bearing frame which supports the operation roll, the end roller is brought into contact with the other side press roll which is not brought into contact with the operation roll and, thereby, parallelism between the operation roll and the press roll can be always maintained.SELECTED DRAWING: Figure 1 【課題】電極板の塗工部と未塗工部でロールプレス作業により生ずる、しわの発生を抑えるしわ発生防止装置を備えたロールプレス機を提供する。【解決手段】しわ発生防止装置はプレスロールより小径の作業ロールをプレスロールに押しつけ、該作業ロールは補強ロールを介して軸受フレームで支持され、均一な押圧力で未塗工部を延伸可能とする。更に、該作業ロールを支持する該軸受フレームの軸端部に端部ローラを配置して、該端部ローラと該作業ロールと接触しない他方のプレスロールと接触させ、常に該作業ロールと該プレスロールの軸芯平行度を維持出来るようにする。【選択図】図１
