Abstract (en)
[origin: WO2015144100A1] The method of the film tube bag production comprises the following operations: - Shaping the longitudinal foldings (6) on the packing film (8), - Attaching the secondary all-round closure (5) on the inner side (21) of the packing film (8). Its longitudinal axis is perpendicular to the longitudinal axis of the longitudinal foldings (6). The length of the secondary all-round closure (5) corresponds to the size of the inside circumference of the bag (1), - Shaping of the packing film (8) into the form of the film tube, - Closing the film tube and creating the folded flat quadrilateral bottom (3), - Filling the bag and forming the upper cross seam (2). The secondary all-round closure (5) can be formed by a one-piece zipper closure, double-sided adhesive tape, or by the spread of a permanent adhesive. The vertical form fill seal packaging machine comprises the device (11) for the packing film (8) unwinding, the device (12) for shaping and fixing longitudinal foldings (6), the device (17) for the application of the one-piece secondary all-round closure (5), forming collar (13), filling tube (14) and the longitudinal sealing jaw (15), the device (19) for the packing film (8) feed, the device (18) for formation of flat bottom (3) of the bag (1), and lateral sealing and separating jaws (16) to form the cross seam (2, 4) and to separate the filled bag (1).
