Claims
- 1. A bag stack comprising a plurality of elongated plastic foil bags each having a pair of opposite sides and formed with an insertion opening through which an article is insertable into the respective bag, one of said sides only of each bag being formed with a suspension element detachable from the respective bag, said suspension elements being interconnected to retain said bags in said stack and being formed with aligned suspension openings proximal to said insertion openings.
- 2. The bag stack defined in claim 1 wherein said insertion openings open into elongated pouches shaped to receive a respective newspaper.
- 3. The bag stack defined in claim 2 wherein one of said sides of each of said bags is formed with a pocket separate from the respective pouch.
- 4. The bag stack defined in claim 3 wherein each of said suspension elements is a tear off segment separated from the respective one side of each bag by a perforation line.
- 5. The bag stack defined in claim 4 wherein the tear off segment is formed by a separate strap fused with the respective one of said sides of the respective bag in an area of the respective insertion opening substantially parallel to the perforation line.
- 6. The bag stack defined in claim 5 wherein said strap is fused to an outside or inside of the respective bag and the bag is provided in said insertion opening with a draw string.
- 7. The bag stack defined in claim 5 wherein said strap is fused to an outside or inside of the respective bag and each bag is provided with a rain protection flap having an adhesive strip.
- 8. The bag stack defined in claim 5 wherein each pocket is attached to a respective bag at an end of the bag opposite the respective insertion opening and has a unilaterally projecting flap at a filling opening for the respective pocket substantially parallel to a respective insertion opening.
- 9. The bag stack defined in claim 8 wherein said flap is formed in one piece of a transparent plastic foil with said pocket.
- 10. The bag stack defined in claim 8 wherein said flap is on the same side as the respective bag as said suspension element.
- 11. The bag stack defined in claim 8 wherein said flap is provided on an inside with an adhesive strip covered by a masking strip.
- 12. A method of continuously producing plastic foil bags interconnectable to form a stack, comprising the steps of continuously feeding first and second plastic foil webs;
forming longitudinal and transverse fusion seams in said webs to define respective bags and forming insertion openings for said bags; attaching a suspension element in a region of the insertion opening of each of said bags by fusing a continuously fed strip to one wall of each of the bags in the area of the respective insertion opening and fusing said strip thereto.
- 13. The method defined in claim 12 wherein said strip is formed of a material other than said foil.
- 14. The method defined in claim 13, further comprising feeding a material capable of forming a pocket to a wall of each of said bags and fusing said material thereto while supplying said material with an offset to a bottom seam of the respective bag to form a flap for closing the respective pocket.
- 15. An apparatus for the continuous production of stacks of interconnected plastic foil bags, said apparatus comprising an unwinding station for unwinding plastic foil webs attached to be fused together to form such bags;
a longitudinal fusion device and a transfer fusion device for fusing said webs together to form said bags whereby said bags for insertion openings; means for feeding a strip to said bags and fusing said strip to one wall only of each of said suspension element detachable from the respective bags; and means for forming a perforation line in the area of said insertion opening between each bag and a portion of said strip forming a respective strap whereby said straps are connectable to assemble a plurality of said bags in a respective stack.
- 16. The apparatus defined in claim 15, further comprising an adhesive strip unwinder for applying adhesive strips for feed bags and a protection strip unwinder for masking strips on adhesive strips.
- 17. The apparatus defined in claim 15 wherein said fusion devices include two fusion separation tools disposed substantially transversely to a direction of advance of said webs and synchronized in respective up and down motions.
- 18. The apparatus defined in claim 17, further comprising a collection device downstream of said fusion separation tools in said direction and formed with pin-type stacking belts receiving the bags with pins projecting through said straps, the bags being held by said pins until they are knocked off by a takeoff device whereby said bags are interlocked in the region of said straps.
- 19. The apparatus defined in claim 17, further comprising a downstream unwinder for applying a drawstring to each of said bags.
