    • A flexible container for lifting transportation and storing of bulk material is manufactured from a hose-like blank, where one half-length portion of the hose-like blank is turned inside out and threaded onto or fitted over the other half-length portion form an inner sack and an outer sack having a common base or individual abases. The hose-like blank has at a mid-length thereof two or more longitudinal slots or openings separated by the same distance around the circumference of the hose-like blank. One half-length portion is rotated with regard to the other half-length portion around a central axis of the hose-like blank, such that the material of the areas between the slots after rotation forms two or more integrated lifting loops.

    • In a process of making T-shirt bags a flat tubular film that is provided on each side with at least one gusset is provided with top end seam welds, which close the gusset portions to form handle loops, and with cutouts, which are similar to the neckline of a T-shirt and extend through the inner creases of the side gussets, and the tubing is then folded on itself about its longitudinal center line and is thereafter formed at its bottom end with seam welds, which join all plies, and is formed between adjacent top end and bottom end seam welds with transverse perforation lines or with hot wire-welded joints to separate adjacent bags from each other. Before the folding of the tubular film on itself about its longitudinal center line those portions of the tubular film which are subsequently provided with the top end seam welds are provided with layers of a release agent which extend across the web and prevent a welding of the web. The tubular film is subsequently folded on itself so that the release agent layers lie on each other. The tubular film which has been folded on itself is subsequently provided with the top end and bottom end seam welds.

    • An apparatus for producing various shapes of polyethylene bags includes a heating mold separating means, a cutting mold separating means and a collecting means. By using such an apparatus for making PE bags, a double-layered polyethylene sheet rolled on a roller is transported into the heating mold separating means by input rollers to form polyethylene bags of any desired shape. Since the bags can not be completely separated from the sheets by heating mold, the bags together with the sheets must be sent into the cutting mold separating means by transporting rollers again. The cutting mold separating means will cut the boundary of the bag except the root portion, so that the bag is completely separated from the sheets, except for the root portion. Finally, the bags together with the sheets are sent into the collecting means. The cutter of the collecting means indents the root portion of the bags and the needles of the collecting means pokes through the root portion of the bags. Therefore, the bags are produced and completely separated from the sheets and then collected in the collecting means. Further, the waste sheets are transported by output rollers to a waste sheet collecting roller for reuse.
    • 用于生产各种形状的聚乙烯袋的设备包括加热模具分离装置,切割模具分离装置和收集装置。 通过使用这样的制造PE袋的装置,在辊上滚动的双层聚乙烯片材通过输入辊输送到加热模具分离装置中,以形成任何所需形状的聚乙烯袋。 由于袋子不能通过加热模具与纸张完全分开,所以袋子与纸张必须通过再次传送辊子被送入切割模具分离装置。 切割模具分离装置将切除除了根部之外的袋的边界,使得除了根部之外,袋与片完全分离。 最后,袋子与纸张一起送入收集装置。 收集装置的切割器缩小袋的根部,并且收集装置的针刺穿袋的根部。 因此,袋子被制造并完全与片材分开,然后收集在收集装置中。 此外,废纸通过输出辊输送到废纸收集辊以重新使用。
