本发明涉及用塑料膜(例如聚乙烯等)卷材生产袋子，该塑料膜从母卷上退卷并经过成形装置以提供所谓的“J”形折叠。更具体地，本发明提供了一种用于生产热焊垫形式的双流侧焊袋的方法和设备，其中当膜从母卷上退卷时，在膜的相对侧上设置两个“J”形折叠以形成两个相对设置的袋，这两个袋可彼此分离，并且适合以堆叠形式安装为焊垫，或者用于安装在小门、销等上。本发明还提供了一种新颖的垫片形式的袋子叠层，适合安装在夹板或类似物上，或者安装在小门、别针等上，并且每个袋子都可与垫片单独分离以接收和包装各种类型的商品。
The invention relates to the production of bags from a web of plastic film, such as polyethylene and the like, which is unreeled from a parent roll and caused to pass over a forming device to provide what is known as a "J" fold. More particularly, it provides a method and apparatus for producing double streams of side-welded bags in heat-welded pad form, wherein two "J" folds are provided on opposite sides of the film as it is unreeled from the parent roll to form two oppositely-disposed bags, severable from each other, and suitably mountable in stacked form as welded pads, or for mounting on wickets, pins, or the like. It also provides a novel stack of bags in pad form adapted to be mounted on clip boards or the equivalent, or on wickets, pins, or the like, and each individually severable from the pad to receive and package various types of merchandise.
