Disclosed therein are method and apparatus for collapsibly stacking continuously formed plastic bags to dispense continuously formed plastic bags from a packing box one by one like tissues dispensed one by one. The method for collapsibly stacking the continuously formed plastic bags includes the steps of : repeatedly pushing the continuously formed plastic bags at a position directly in front of a cutter part, which forms a cut portion on each plastic bag, in a fixed timing period using rollers; supporting a half of the length of the front part of the plastic bag pushed out by the rollers using a supporter; gradually lowering the supporter from an initially ascended height of the supporter, as much as a thickness of each collapsed plastic bag; sucking and fixing a central portion of the supplied plastic bag just near to the rollers of the supporter using a suction tube; pushing the plastic bag using the rollers in a state where the central portion of the plastic bag is fixed by the suction tube to thereby collapse the fixed portion; and fixing a central portion of the next plastic bag again using the suction tube while completely collapsing the collapsed plastic bag by pressing the plastic bag using a pressing plate, and continuously repeating the above steps. |
