To provide a paper feeding method capable of feeding side-opening envelope base paper of a type in which a notch is formed at a center in a width direction of an end part of a rear surface part of the base paper.SOLUTION: A paper feeding method for pulling out side-opening envelope base paper, in which a notch 1c is formed at a center in a width direction of an end part of a rear surface part 1b of the base paper, one by one from a laminated body 1' of the side-opening envelope base paper, includes a suction step for sucking the rear surface part 1b of the side-opening envelope base paper in the lowest layer of the laminated body 1' to hold the same by suction blocks 14, 14 by actuating suction ports 14a, 14a opened at the suction blocks 14, 14. The number of the suction ports is two or more, and the rear surface part of the base paper is held by the suction blocks 14, 14 at least at both ends in the width direction of the notch.SELECTED DRAWING: Figure 3 【課題】原紙裏面部の端部の幅方向中央に切り欠きが形成されたタイプの洋封筒原紙を給紙可能な給紙方法を提供する。【解決手段】原紙裏面部１ｂの端部の幅方向中央に切り欠き１ｃが形成された洋封筒原紙の積層体１'から該洋封筒原紙を１枚ずつ抜き出す給紙方法であって、吸込ブロック１４，１４に開口形成された吸口１４ａ，１４ａを作動させることによって、積層体１'の最下層にある洋封筒原紙の原紙裏面部１ｂを吸い込んで吸込ブロック１４・１４に保持させる吸込工程を含む。吸口の数は、２以上であり、原紙裏面部は、少なくとも切り欠きの幅方向両端において吸込ブロック１４，１４に保持される。【選択図】図３
