    • The invention describes a bag machine for production of bags made of paper material, comprising: an unwinding device to unwind and feed to the machine material made of paper in a transport direction (x), a device to produce weakening lines, having a trend, in which parts of these weakening lines are offset relative to each other in direction (x), so that a first wall of the finished bag continues in at least one tab that extends beyond the second wall, a tube-forming device to form a tube, in which the side areas of the sheet can be folded to form an overlapping area and join to each other, a separation device to separate the tube sections along the weakening lines from the tube, and a bottom formation device, in which areas of the leading end of the tube section can be folded and fastened onto an outer wall of the tube section. A device for application of adhesive surfaces to the paper materials is provided, with which an adhesive surface can be applied to an area of the paper material, which represents the side of the tab facing the second wall in the finished bag.
    • 本发明描述了一种用于生产由纸材料制成的袋子的袋机,包括:退绕装置,用于在输送方向(x)上退纸并供给由纸制成的机器材料,产生弱化线的装置,具有趋势, 其中这些弱化线的哪些部分在方向(x)上相对于彼此偏移,使得成品袋的第一壁在延伸超过第二壁的至少一个突片中继续,管形成装置形成管 其中片材的侧面区域可以被折叠以形成重叠区域并且彼此接合,分离装置将管部分沿着弱化线与管分离,底部形成装置的区域 管部分的前端可折叠并固定在管部分的外壁上。 提供了一种用于将粘合剂表面施加到纸张材料的装置,通过该装置可以将粘合剂表面施加到纸材的区域中,该区域表示在成品袋中面向第二壁的突片的侧面。
