    • Provided is a bag making machine for making a bag with an angled bottom by a system different from the conventional system. Body materials of an upper layer and a lower layer are overlapped with each other and fed in the length direction. Furthermore, a bottom gusset material is fed to the body material of one layer and laid on the outer surface thereof, and one side edge of the bottom gusset material is arranged along one side edge of the body material. After the overlap of body material of the upper and lower layers and the feed of bottom gusset material, the bottom gusset material and the body material of the other layer are bonded at the one side edges thereof and fixed temporarily. As the body material is fed thereafter, the body material of one or the other layer and the bottom gusset material are guided by a guide mechanism of body material and bottom gusset material near one side edge of the body material, and the body material of one or the other layer is bent to combine the bottom gusset material with the body material of both layers. Body portion of a plastic bag is formed of the body material of both layers and the bottom gusset portion of the plastic bag is formed of the bottom gusset material.
    • 本发明提供一种用于通过与传统系统不同的系统制造具有倾斜底部的袋的制袋机。 上层和下层的主体材料彼此重叠并在长度方向上进给。 此外,底部角撑板材料被馈送到一层的主体材料并放置在其外表面上,并且底部角撑板材料的一个侧边缘沿着主体材料的一个侧边缘布置。 在上层和下层的主体材料重叠和底部角撑板材料的进料重叠之后,另一层的底部衬垫材料和主体材料在其一个侧边缘处结合并暂时固定。 随着主体材料之后,一个或另一个层的主体材料和底部角撑板材料由主体材料的引导机构和靠近主体材料的一个侧边缘处的底部角撑板材料引导,并且一个主体材料 或者另一层弯曲以将底部角撑板材料与两层的主体材料组合。 塑料袋的主体部分由两层的主体材料形成,塑料袋的底部角撑部分由底部角撑板材料形成。
