    • PROBLEM TO BE SOLVED: To prevent a position lag of an envelope paper and contents during conveying and occurrence of paper jam.SOLUTION: An envelope paper P2 used to manufacture an envelope comprises: a rectangular first composition paper 107 having a flap unit 117 which can open and close at one end side of an envelope expand direction; a rectangular second composition paper 109 provided to link with the first composition paper 107 through a first folding unit 111 and along the envelope expand direction; and a rectangular third composition paper 113 provided to link with the second composition paper 109 through a second folding unit 115 and along the envelope expand direction and formed an adhesive coating unit 123 coated with adhesive to close a flap unit 117 along a direction at right angles to the envelope expand direction. A length Lin of the envelope expand direction ED of the third composition paper 113 is not less than a distance between a conveying roller 74 and a conveying roller 76 in the envelope expand direction (envelope conveying direction) ED.
    • 要解决的问题:防止信封纸和内容物在传送和发生卡纸期间的位置滞后。解决方案:用于制造信封的信封纸P2包括:矩形第一组合纸107,其具有襟翼单元117,其可以 在信封扩展方向的一端侧打开和关闭; 设置成通过第一折叠单元111沿着包络线展开方向与第一构图纸107连接的矩形第二构图纸109; 以及设置成通过第二折叠单元115并且沿着包络线展开方向与第二组合纸109连接的矩形第三组合纸113,并且形成涂覆有粘合剂的粘合剂涂布单元123,以沿着直角的方向关闭襟翼单元117 到信封展开方向。 第三构图纸113的包络线扩展方向ED的长度Lin不小于在包络线膨胀方向(信封传送方向)ED上的输送辊74和输送辊76之间的距离。
