Method for the manufacture of a sack for lifting, transporting and storing bulk goods. The sack is made from a tubular fabrication 5, in which one half 10 of the tube is turned inside out over the second part 11 to form an inner 10' and an outer 11' container, which are each provided with their own or a common bottom construction. The tubular fabrication is provided at its centre section with two or alternatively more longitudinal slits or holes 6, 7 especially at uniform intervals from one another in the circumferential direction of the tubular fabrication. One half 10 is twisted about the longitudinal axis 12 of the tubular fabrication relative to the second half 11, the sections of material between the slits after turning inside out thereby forming two or more integral carrying straps 4. |
