    Abstract: A system for folding napkins feeds a continuous web over a folding board for producing a longitudinal fold in the web, the web is then severed transversely to form discrete segments which are transversely folded and creased by a first vacuum folding roll, the crease occurring transversely at a location intermediate the first transverse fold and the opposite edge of the segment. A second vacuum folding roll rotating adjacent the first then lifts the creased segment from the first folding roll at a location adjacent the crease to fold the segment along the crease line and thereby form an eight-ply napkin.

    Abstract translation: 用于折叠餐巾的系统将一个连续的纸幅供给到折叠板上，用于在幅材上产生纵向折叠，然后横向地切割幅材以形成由第一真空折叠辊横向折叠和折皱的离散片段，折痕横向于 位于第一横向折叠和该段的相对边缘之间的位置。 与第一折叠辊相邻旋转的第二真空折叠辊然后在邻近折痕的位置处从第一折叠辊提起折痕段，以沿着折痕线折叠片段，从而形成八层餐巾。

    CPC classification number: B65B63/04

    Abstract: A machine for introducing a twice-folded stack of bags into a carton wherein the bags are singly delivered through a first path to a partial folding support, thereafter a partially folded stack being conducted along a second path into a housing consisting of two pivotally interconnected jaws and finally the once-folded stack is ejected from the housing which achieves a second fold in the stack incident to introducing the twice-folded stack into a carton.

    Abstract translation: 一种用于将两倍折叠的袋子引入纸箱中的机器，其中袋子通过第一路径单独地传送到部分折叠支撑件，之后将部分折叠的堆叠沿着第二路径传导到由两个枢转互连的夹爪 并且最后一次折叠的堆叠从壳体中弹出，在堆叠中实现第二折叠，以将两次折叠的堆叠引入纸箱中。
