Abstract
A form-fill-seal machine and a method for manufacturing and filling a bag (100) having a drawstring tape or cord. The form-fill-seal machine includes a device to guide a film on the machine. A conveying device positions at least one drawstring tape or cord on the film. A folding device folds the film to form a first sheet and a second sheet of the bag. First and second welding jaws weld the first sheet and the second sheet to close two sides of the bag and leave a third side of the bag open. A filling chute fills the bag by the third side of the bag. Third welding jaws close the bag by sealing the third side.

A form-fill-seal machine (200, 300, 400, 500) for manufacturing and filling a bag (100) provided with a drawstring, said bag including a first sheet (112) and a second sheet (114) forming together a first edge (117) and a second edge (118) of the bag, and a closing device (120) including a drawstring, the form-fill-seal machine comprising:
- a device (210, 310, 410, 510) configured to guide a film (1) on the machine,
- a conveying device (215, 315, 415, 515) configured to position at least one drawstring (136, 146) on the film,
- a folding device (240, 340, 440, 540) configured to fold the film (1) so as to form the first sheet (112) and the second sheet (114) of the bag,
- first and second welding jaws (245a-b, 345a-b, 445a-b, 545a-b) configured to weld the first sheet (112) and the second sheet (114) so as to close two sides of the bag and leave a third side of the bag open,
- a filling chute (250, 350, 450, 550) configured to fill the bag by the third side of the bag, and
- third welding jaws (255, 355, 455, 555) configured to close the bag by sealing the third side,
- wherein the conveying device (215, 315, 415, 515) is configured to position the drawstring (136, 146) on the film in a direction transversal to a travel direction of the film (1).
A form-fill-seal machine (200, 300, 400, 500) for manufacturing and filling a bag (100) provided with a drawstring, said bag including a first sheet (112) and a second sheet (114) forming together a first edge (117) and a second edge (118) of the bag, and a closing device (120) including a drawstring, the form-fill-seal machine comprising:
- a device (210, 310, 410, 510) configured to guide a film (1) on the machine,
- a conveying device (215, 315, 415, 515) configured to position at least one drawstring (136, 146) on the film.
A method (S10, S20) for manufacturing and filling a bag (100) provided with a drawstring by means of a form-fill-seal machine (200, 300, 400, 500), said bag comprising a first sheet (112) and a second sheet (114) forming together a first edge (117) and a second edge (118) of the bag, and a closing device (120) including a drawstring, the manufacturing and filling method comprising the following steps:
- guiding (S11, S21) a film (1) on the machine,
- positioning (S13, S23) at least one drawstring (136, 146) on the film,
- folding (S16, S26) the film (1) so as to form the first sheet (112) and the second sheet (114) of the bag,
- welding (S17, S27) the first sheet (112) and the second sheet (114) so as to close two sides of the bag and leave a third side of the bag open,
- filling (S18, S28) the bag (100) via the third side of the bag, and
- closing (S19, S29) the bag (100) by sealing the third side
- wherein the drawstring (136, 146) is positioned (S13) on the film in a direction transversal to a travel direction of the film (1).
