摘要： A supply of hose-shaped wrapping material is pleated axially and fits telescopically about the outer surface of a forming tube. A portion of the wrapping material extends over the upper rim of the tube and downwardly through the tube bore to a position below the lower rim of the tube where it is fastened in a tightly gathered together manner. A gate, positioned below the lower rim of the tube, supports articles fed into the wrapping material in the tube bore. This gate is movable to a position which allows the articles and wrapping material to drop downwardly through the bore to a position below the gate. Such downward movement of the wrapping material draws another portion of wrapping material into the bore of the forming tube. By supporting the wrapping material and accumulated articles at a position above the fastened end of the wrapping material, the lowermost article within the wrapping material will drop from the position of support to the fastened end of the wrapping material upon removal of the support. This results in a downward pull on the wrapping material to break up any bridging of articles in the tube. After one batch of articles in the wrapping material has dropped below the gate, the gate returns to a position underlying the forming tube for supporting another batch of articles while the wrapping material below the gate and above the first batch of articles is being fastened and severed to provide the completed article package.
摘要翻译：软管形包装材料的供应物轴向地打褶并围绕成形管的外表面可伸缩地配合。包裹材料的一部分在管的上边缘上延伸并向下延伸通过管孔到位于管的下边缘下方的紧固在一起的方式的位置。位于管的下边缘下方的门支撑进入管孔中的包装材料的物品。该门可移动到允许物品和包裹材料通过孔向下落到位于门下方的位置的位置。包装材料的这种向下运动将另一部分包装材料吸入成形管的孔中。通过在包装材料的紧固端的上方的位置支撑包裹材料和积聚的物品，包装材料中的最下面的物品在移除支撑件时将从支撑件的位置下降到包裹材料的紧固端。这导致包裹材料向下拉，以破坏管中物品的任何桥接。在包装材料中的一批物品落在浇口下方之后，浇口返回到成形管下方的一个位置，用于支撑另一批物品，同时门下方的包装材料和第一批物品上方的包装材料被固定和切断提供完整的文章包。
