FIELD: packing. SUBSTANCE: according to proposed method, at least two tapes of foil are fed to form sides of foil bags which are connected to each other after which sleeve, thus formed, is cut into separate bags. If two foil feeders deliver different amounts of foil material to make foil bags, difference is eliminated by stretching the foil tape which provides less amount of material for bag. Gag making device operates on proposed principle. EFFECT: prevention of deviations in amounts of foil material designed for forming separate sides of foil bag. 23 cl, 5 dwg
