Summary:PROBLEM TO BE SOLVED: To provide a stable web feeding method and a web feeding device used for the same without varying a position of a web passing under feeding according to a feeding process and a lot of the web in roll-to-roll.SOLUTION: In at least a part of a section for feeding a web 2, by supporting both side edge parts of the web 2, a center part in a width direction of the web 2 is bent as a lowermost part, and in this state, the web 2 is fed. The supporting is performed by, for example, forming a through hole 2a at both the side edge parts of the web 2, and inserting a protruding part 12a formed on an upper surface of one end part of an arm 12, from the lower side of the web 2 into the through hole 2a.SELECTED DRAWING: Figure 2 【課題】ロールトゥロールにおいて、送給中のウエブの通る位置が、そのウエブの送給過程およびロットによってばらつくことなく、安定しているウエブ送給方法およびそれに用いるウエブ送給装置を提供する。【解決手段】ウエブ２を送給する少なくとも一部の区間において、ウエブ２の両側縁部を支持することにより、ウエブ２の幅方向の中央部を最下部として撓ませ、その状態で、ウエブ２を送給する。上記支持は、例えば、ウエブ２の両側縁部に貫通孔２ａを形成し、ウエブ２の下側から、その貫通孔２ａに、アーム１２の一端部上面に形成された突起部１２ａを挿入することにより行われる。【選択図】図２
