    • 专利摘要:
    Lined plastics sacks are made from tube sections successively severed from a tubular web consisting of a tubular inner layer of thermoplastic film around which a circular fabric of stretched plastics tapes is woven to form an outer layer. In each severed tube section, the layers are interconnected by a seam at one end to define a sack. The outer layer may be formed with side pleats defining three outwardly directed folds, the inner layer being flattened and disposed in the central such fold before the sack is filled.

    (54) METHOD OF MAKING DOUBLE BAGS
    and 8 to form lateral folds 9 and 10, as well as panels 11-14 for forming lateral folds 15 and 16, directed inward.
    Thus, after passing the forming device, the outer sleeve is molded with two lateral folds 15 and 16 directed inward and the inner sleeve is located between the folds 15 and 16 in fold 6 directed to the outer side. canvases 17 and the formation of bottom seams 18 on these segments.
    The present method makes it possible to manufacture bags of various sizes with high strength. The bag is filled with the product, has good stability due to the bottom, which takes the form close to the hexagon.
