到目前为止，专家们认为目前使用的信封上都不再加以改进长期发展的结果是。 当寻找信封制造和现在可以实现的节省的分布是，具有相对小的变化相对于已知的信封在生产材料制成，并且还在运输和存储空间，一方面可节省。 包络，这是erfülltm由Stänzling，它有两个完全笔直的这种条件下，彼此平行侧向边界边缘（2,3），使得它，但是，可以在不额外的侧向成形仅通过切断产生的从恒定宽度的直的纸幅， 并且所述闭合折板（4）的自由边缘的主要部分，以形成特定的切削刃（5）到相对的切削刃（6），其中后者的特定边缘是限制在信封的填充开口的互补性，以使切割的Stänzlings时 纸是没有浪费。

So far, the experts believe that currently used envelopes are no longer to be improved result of a long development were. In the search for savings opportunities with regard to the envelope manufacturers and including sale could now be achieved with a relatively small change compared to the known envelopes one hand in the preparation of material and the other part in the transport and storage space can be saved. The envelope, which is erfülltm this condition made of a Stänzling which has two completely straight, to mutually parallel lateral boundary edges (2, 3) so that it, from a straight paper web of constant width merely by cutting off, but can be produced without additional lateral shaping and that to form the substantial part of the free edge of the closure flap (4) specific cutting edge (5) to the opposite cutting edge (6) runs complementary, the latter of which the specific edge is to limit the filling opening of the envelope, so that when cutting a Stänzlings of the web no waste.
