    • The invention relates to a method and a device for producing foil bags comprising V-shaped inserted lateral folds and a reclosing mechanism with a slide in a top filling hole. The inventive method encompasses the following steps: window-shaped blanks (10) which delimit the top end of the subsequently formed lateral folds as well as slide blanks (11) are introduced into a planar sheeting. Reclosing mechanisms (6) that are composed of two superimposed and interconnected profiled strips and a slide are placed on the planar sheeting (2) perpendicular to the direction of the sheeting in such a way that the slides lie inside the slide blanks (11). The reclosing mechanisms (6) are connected to the sheeting only at the ends. The sheeting (2) is then directed through a folding station (7) in which the sheeting is folded and lateral folds are molded thereinto. The reclosing mechanisms (6) are joined to the sheeting by means of a sealing seam while the top end of the lateral folds is incorporated thereinto. The superimposed foil layers are finally joined by means of additional sealing seams so as to obtain a run (16) of bags which comprises bag-shaped sections and from which individual foil bags (17) are cut off.
    • 本发明涉及一种方法和用于制造薄膜袋,其具有V形插入侧的褶皱和具有在头部侧填充物的滑块可再密封的闭合装置。 该方法包括以下方法步骤:在平面薄膜幅为窗状冲压出的(10),其限定后面形成的侧折叠部的上端,以及滑动冲痕部分(11)被引入。 此后,重新封闭件由两个叠置的和互连的轮廓条的和滑块横向放置到网络方向,从而所述平面薄膜带(2)(6),即在滑动冲痕部分的载玻片(11)。 可再密封的封闭件(6)在端部处的薄膜状片仅连接。 随后,通过折叠工位(7)薄膜带(2)被引导,在膜和侧折叠的折叠幅材中形成。 可再密封的封闭件(6)通过包含侧的上端的下一个密封接缝而连接折叠与材料带。 最后,另外的密封接缝由袋状部袋链(16)的一组叠置薄膜层被连接的个人铝箔袋(17)是分开的。

    • In a process and in an apparatus for making bags (50), a film (51), preferably a flexible plastic film, is fed from a suitable roll (53) and at least one indented pleated portion is made in the film (51), in particular a first and a second indented pleated portions (56, 58) having a first and a second flap (56a, 56b and 58a, 58b), wherein the corresponding indented pleated portion (56, 58) has at least one respective longitudinal end (56', 56" and 58', 58"). Advantageously, a corresponding part (56'a, 56"a, 58'a, 58"a) of the pleated portion (56a, 58a) is joined to a corresponding part (546a, 546b, 548a, 548b) of the film face (52) opposite, immediately after, or downstream of, the step of forming the pleats (56, 58) and, in any case, before making the film (12) into a tube. The invention also relates to a bag made of flexible plastic film.
    • 在制造袋子(50)的过程和装置中,从合适的辊子(53)供给膜(51),优选为柔性塑料膜,并且在膜(51)中制造至少一个缩进的褶皱部分, ,特别是具有第一和第二翼片(56a,56b和58a,58b)的第一和第二缩进褶皱部分(56,58),其中对应的缩进褶皱部分(56,58)具有至少一个相应的纵向 (56',56“和58',58”)。 有利的是,褶皱部分(56a,58a)的对应部分(56'a,56“a,58'a,58”a)连接到膜面的相应部分(546a,546b,548a,548b) (52),紧接在形成褶皱(56,58)的步骤之后或之后,并且在任何情况下,在将膜(12)制成管之前。 本发明还涉及一种由柔性塑料薄膜制成的袋子。
