摘要： A lapel provided at the one end of a paper sheet to forming a paper bag is introduced into the interior of an opening on the rotary cylinder by means. The folding blade has a rotational axis located outside the rotary cylinder parallel to an axis of rotation of the rotary cylinder. The thus bent lapel is brought in pressure contact with the edge face of the opening by means of a holding pawl which turns in operative association with the rotary cylinder. Thereafter, the lapel is covered and depressed by means of a depressing pawl which turns in operative association with the rotary cylinder whereby the lapel and a part of the paper sheet are adhesively secured to one another to build a double-walled structure around the opening of the paper bag.
摘要翻译：设置在纸张一端以形成纸袋的翻领通过装置被引入旋转圆筒上的开口的内部。折叠刀片具有与旋转圆筒的旋转轴线平行的旋转圆筒外侧的旋转轴线。这样弯曲的翻领通过与旋转圆筒有效关联的保持爪与开口的边缘面压力接触。此后，通过与旋转筒操作关联的揿压爪将翻领部覆盖和压下，由此将翻领部分和纸张的一部分彼此粘结固定，从而在开口周围形成双层壁结构纸袋。

摘要： A paper bag is formed from a single sheet of paper by folding the same to produce a final generally rectangular bag or receptacle with an open end. The upper edge portion around the bag opening is folded in and glued to provide greater strength thereat. During the folding and glueing of this opening strength turned-in collar, two carrying handles are also glued in, one on each of the bag's largest sides. According to this invention, a corner portion at one end of the turned-in collar portion is cut out and enables glueing thereat to an inner surface rather than the typically smoother outer surface of the paper, thereby providing improved strength to the reinforced opening of the bag.
摘要翻译：纸袋由单张纸通过折叠形成，以产生具有开口端的最终大致矩形的袋或容器。袋开口周围的上边缘部分被折叠并粘合，以在其上提供更大的强度。在打开这个开启强度的衣领的折叠和胶合过程中，两个手提把手也粘合在一个袋子最大的一侧。根据本发明，切入衣领部分的一端的拐角部分可以在内表面而不是通常平滑的纸张的外表面上粘合，从而为加强开口的加强开口提供了改进的强度袋。

摘要： In a method of manufacturing a pleated multi-layer bag, a tubular synthetic resinous film collapsed flatly, with each side edge of the film folded inwardly to form a pair of pleats extending along the side edge, is laid upon a length of an outer-layer bag material. The film and the bag material are transported while one of the pair of pleats at each side edge of the film is set upright to form an upstanding section. Subsequently, opposite side portions of the outer-layer bag material are folded back toward the tubular synthetic resinous film. The upstanding section is folded down toward the other pleat. A part of each of the opposite side portions is forced into a space between the upstanding section and the other pleat at a corresponding one of the opposite side edges of the tubular synthetic resinous film. The opposite side portions of the outer-layer bag material are folded over the tubular synthetic resinous film in such a manner that the opposite side portions extend along the outer surface of the film. The resinous film and outer-layer bag material are then united and selected lengths thereof cut and sealed at one end to form bags. The method maintains the tubular synthetic resinous film in its collapsed state through the various steps, thereby avoiding entry of dirt, germs or bacterial into the bag as it is being manufactured.
摘要翻译：在制造褶皱多层袋的方法中，管状合成树脂膜平坦地折叠，薄膜的每个侧边缘向内折叠以形成沿着侧边缘延伸的一对褶皱，层袋材料。传送薄膜和袋材料，同时将薄膜的每个侧边缘处的一对褶皱中的一个设置成直立以形成直立部分。随后，外层袋材料的相对侧部分朝向管状合成树脂膜折回。直立部分朝向另一褶皱折叠。每个相对侧部分的一部分在管状合成树脂膜的相对的一个边缘中被迫进入直立部分和另一个褶皱之间的空间中。外层袋材料的相对侧部分以这样的方式折叠在管状合成树脂膜上，使得相对侧部分沿膜的外表面延伸。然后将树脂膜和外层袋材料合并，并在一端切割并密封其选定长度以形成袋。该方法通过各种步骤将管状合成树脂膜保持在其折叠状态，从而避免污垢，细菌或细菌在制造时进入袋中。
