    • The invention relates to a device and a method for forming a bottom opening (8) between bag sections (2', 2'') at the open end region (9) of a tubular bag body (2), comprising a transport device (3) for transporting the bag body (2) in a transport direction (5) transversely to its longitudinal extension (6), and an opening device (7) for forming the bottom opening (8) between the bag sections (2', 2'') at the open end region (9) of the tubular bag body (2). According to the invention, the opening device (7) comprises at least two spreading elements (10) in the form of wedge elements (12; 12', 12'', 12'''), which are successively arranged in the direction of transport (5) of the tubular bag body (2) and which are provided with edge surfaces (14; 14', 14'') rising counter to the rotational direction (13), by which the bag sections (2', 2'') can be spread apart at the open end region (9) of the tubular bag body (2) during the transport thereof on the transport device (3), wherein the wedge elements (12; 12', 12'', 12''') of successive spreading elements (10) have different wedge heights (h), which increase in the direction of transport (5) of the tubular bag body (2), preferably perpendicular to the support surface (4) for the tubular bag body (2) on the transport device (3).
    • 本发明涉及一种用于在袋状体(2)的开口端部区域(9)处的袋状部分(2',2“)之间形成底部开口(8)的装置和方法,该装置和方法包括运输装置 (2',2)之间形成底部开口(8)的开口装置(7),所述开口装置(7)用于沿横向于其纵向延伸部(6)的运输方向 (2)的开放端部区域(9)处。 根据本发明,开启装置(7)包括至少两个呈楔形元件(12; 12',12“,12”)形式的扩展元件(10),其沿着 (2')的输送装置(5)并且设置有与旋转方向(13)相反地升高的边缘表面(14; 14',14“),袋部分(2',2' ')在运输装置(3)上运输期间可以在袋状体(2)的敞开端部区域(9)处分开,其中楔形元件(12; 12',12“,12' ')具有不同的楔形高度(h),所述楔形高度(h)沿管状袋体(2)的运输方向(5)增加,优选垂直于用于管形袋的支撑表面(4) (2)在运输装置(3)上。
