    • A folding apparatus comprises:
      - a feed unit (10) for supplying a medium (44) to be folded,
      - a folding substrate (12;12';62) forming a convexly curved support surface for the medium (44) and adapted to be driven back and forth in circumferential direction of said support surface, and

      - a pinch and guide structure (14) for folding and guiding the medium (44) on the support surface.
      The pinch and guide structure (14) comprises two endless belts (28) each of which is arranged to have a belt portion (28a) held in mating engagement with a portion of the curved support surface, so that the two endless belts (28) define two separate paths for the medium (44),
      and wherein the folding substrate and the pinch and guide structure define a closed circulation path in which the two separate paths are joined at a point remote from the feed unit.
    • 折叠装置包括: - 用于供应要折叠的介质(44)的进给单元(10), - 形成用于所述介质(44)的凸形弯曲的支撑表面的折叠基板(12; 12'; 62) 在所述支撑表面的圆周方向上来回驱动,以及 - 用于折叠和引导所述支撑表面上的所述介质(44)的夹紧和引导结构(14)。 夹紧和引导结构(14)包括两个环形带(28),每个环形带被布置成具有保持与弯曲支撑表面的一部分配合接合的带部分(28a),使得两个环形带(28) 限定用于介质(44)的两个独立的路径,并且其中折叠基板和夹紧和引导结构限定了闭合循环路径,其中两个单独的路径在远离进给单元的点处相连接。

    • The invention relates to a method for folding a medium (20) in a folder (1), which folder comprises a rotatable folding cylinder (10), a first rotatable press member (11), which first rotatable press member is capable of engaging with said folding cylinder to form a first folding pinch, a second rotatable press member (12), which second rotatable press member is capable of engaging with said folding cylinder to form a second folding pinch, and a medium feed means (13,14), the method comprising the steps of a) feeding the medium with the medium feed means towards the folding cylinder (10) in between the first and second pinch; b) directing the medium into the first folding pinch, formed by engaging said first rotatable press member (11) with said folding cylinder, by rotating the folding cylinder in a first direction; c) forming a blouse in the medium in between said feed means (13,14) and the folding cylinder (10); d) moving said blouse into said second pinch by rotating the folding cylinder in a second direction, opposite to the first direction. The invention also relates to a folding apparatus and a printing system comprising an in-line combination of a printing engine and a folding apparatus according to the invention.
    • 本发明涉及一种用于折叠文件夹(1)中的介质(20)的方法,该夹具包括可旋转的折叠圆筒(10),第一可旋转的压力构件(11),该第一可旋转的压力构件能够与 所述折叠缸形成第一折叠夹紧件,第二可旋转的挤压构件(12),所述第二可旋转的压力构件能够与所述折叠缸接合以形成第二折叠夹紧件,以及介质供给装置(13,14) 所述方法包括以下步骤:a)将所述介质与所述介质供给装置一起向所述第一和第二夹紧之间的所述折叠圆筒(10)供给; b)通过沿着第一方向旋转折叠圆筒,将介质引导到第一折叠夹头中,所述第一折叠夹紧件通过使所述第一可旋转的压力构件(11)与所述折叠缸接合而形成; c)在介质中在所述进料装置(13,14)和折叠圆筒(10)之间形成衬衫; d)通过沿着与第一方向相反的第二方向旋转折叠圆柱体,将所述上衣移动到所述第二夹头中。 本发明还涉及一种折叠装置和打印系统,其包括根据本发明的打印引擎和折叠装置的在线组合。
