    • An apparatus is disclosed for packaging large stacks of sheet material such as reams (10) of folio-sized paper. The reams are positioned on a precut bottom carton blank (24) and conveyed to a folding station (110). A top carton blank (50) is then positioned on the upper surface of the ream. Then peripheral flaps (34, 36, 42, 44, 46, 48) on the bottom carton blank are folded upward adjacent the sides of the ream. The preglued side flaps (58, 60) and end flaps (70, 72) of the top carton blank are folded downward into contact with the flaps of the bottom carton blank. All folding operations are performed as the ream moves along an essentially straight path through the apparatus, thus providing a compact packaging system.
    • 公开了一种用于包装大堆纸张材料的装置,例如对开尺寸纸张的纸张(10)。 绞盘定位在预切底部纸板箱(24)上并被输送到折叠站(110)。 然后将顶部纸板箱(50)定位在料盘的上表面上。 然后底部纸箱坯料上的周边折板(34,36,42,44,46,48)向上折叠,靠近纸条的侧面。 顶部纸箱坯料的预先磨边的侧翼(58,60)和端部折板(70,72)向下折叠以与底部纸箱坯件的折片接触。 所有的折叠操作都是沿着基本上直线穿过设备的路径进行的,因此提供了紧凑的包装系统。
