Its job step is：Two cylinder rods of double-acting cylinder 90 all stretch out to two ends respectively under original state, cylinder 96 Cylinder rod is to retract, and needs to carry out the 3rd to the position of third time fold line 84 of polybag 8 after the completion of handle folding work During secondary folding, the cylinder rod that double-acting cylinder 90 opens two ends is retracted all into cylinder, and two pressure arms 91 of driving are through the edge of sliding block 92 Line slideway 93 is mobile to centre, so that the inwardly i.e. middle stretching of polybag 8 of two strip plates 9 is driven, when two bar shapeds After pressing plate 9 is fully extended, cylinder 96, which is opened, promotes rocking arm 95 to make rotating shaft 94 together with line slideway 93, sliding block 92, pressure arm 91 Simultaneously to lower swing, so that the position of the third time fold line 84 of polybag 8 is pressed under two strip plates 9, will third time Fold line position and its rear portion are pressed abd fixed on folding platform.Folding turnover 2 swings upset by the handle portion of polybag 8 afterwards Divide and be folded on folding platform 3, the release of double-acting cylinder 90 afterwards is resetted, and two strip plates 9 are retracted to both sides respectively, two Strip plate 9 is extracted out all from foldable formed polybag, and the lifting of folding platform 3 and foldable formed plastics are not influenceed The discharge of bag.

The advantage of example IV is：Turnover panel resigning breach 23 or turnover panel paw 24 need not be set on turnover panel 2, also without must Pressing plate resigning breach 40 is set；Described strip plate 9 can also be substituted with depression bar, optical axis of cylinder etc., easy to process. It has the disadvantage that pressing plate needs that the amplitude stretched out to both sides is larger, and this can cause the volume of punching machine wider, is especially applied to double Its volume is huger after on line punching machine.
