Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a roll press method and a roll press facility of an electrode material which allows for easy adjustment of the amount of an electrode material to be stretched on an uncoated part, while suppressing the creasing of the electrode material.SOLUTION: Only the uncoated part of an electrode material, on which a tension is applied between guide rolls, is stretched using an uncoated part stretching mechanism, and then the electrode material is roll pressed. The uncoated part stretching mechanism is configured to generate a tension in the electrode material between two guide rolls, and includes a pressing roll for pressing the electrode material with a predetermined press-in quantity between the guide rolls. 【課題】電極材料の未塗工部の延伸量の調整を容易に行うことができ、電極材料に皺が発生することを抑制することが可能な電極材料のロールプレス方法及びロールプレス設備を提供する。【解決手段】ガイドロール間で張力がかかった電極材料の未塗工部のみを未塗工部延伸機構を用いて延伸させ、その後、電極材料をロールプレスする。未塗工部延伸機構は二つのガイドロール間で電極材料に張力を発生するように構成し、ガイドロール間において電極材料に対して所定の押込み量で押し付ける押付けロールを備える。【選択図】図４(ａ)
