Abstract

A strapping device for strapping packages, having a packing table via which the package is moved along a movement path through the device, having a strapping frame which is oriented transversely with respect to the movement path and through which the package passes during its movement through the device, having a strap channel which is open in the direction of the frame interior, is formed by the strapping frame and has at least two vertical channel legs which are arranged on both sides of the movement path of the package, and having a multiplicity of strap channel flaps which are secured on the strapping device channel so as to be moveable by way of an articulated leg and are provided with a covering leg which overlies approximately half of the channel opening in the direction of a strap channel longitudinal axis.

First claim

The invention claimed is:

1. A strapping device comprising:
a packing table;
a strapping frame at least partially above the packing table and at least partially defining a strap channel having a strap channel opening;
a pair of first strap channel flaps connected to the strapping frame, each first strap channel flap comprising a first covering leg that overlies part of the strap channel opening, each first covering leg comprising an upwardly extending covering extension; and
a pair of second strap channel flaps connected to the strapping frame adjacent to the pair of first strap channel flaps, each second strap channel flap comprising a second covering leg that overlies part of the strap channel opening, each second covering leg comprising an upwardly extending covering extension, wherein each second covering leg overlies at least part of a respective one of the first covering legs of the pair of first strap channel flaps,
wherein each first strap channel flap is movable independently of each second strap channel flap between an open position and a closed position.

2. The strapping device of claim 1 , wherein one of the second covering legs of the pair of second strap channel flaps partially defines a wedge-shaped strap pull-out contour.

3. The strapping device of claim 1 , wherein each of the first covering legs of the pair of first strap channel flaps partially defines a first wedge-shaped strap pull-out contour, and wherein each of the second covering legs of the pair of second strap channel flaps partially defines a second wedge-shaped strap pull-out contour.

4. The strapping device of claim 1 , wherein one of the second covering legs of the pair of second strap channel flaps partially defines a wedge-shaped strap pull-out contour, and said second covering leg comprises a tip and widens from the tip to partially define the wedge-shaped strap pull-out contour.

5. The strapping device of claim 1 , wherein the upwardly extending covering extension of one of the second covering legs of the pair of second strap channel flaps extends at an increasing distance away from the strap channel.

6. The strapping device of claim 1 , wherein each second covering leg of the pair of second strap channel flaps overlies approximately half of a respective one of the first covering legs of the pair of first strap channel flaps.

7. The strapping device of claim 1 , wherein each second covering leg of the pair of second strap channel flaps overlies a parting joint between the first strap channel flap and the second strap channel flap, respectively.

8. The strapping device of claim 1 , wherein one of the second covering legs of the pair of second strap channel flaps partially defines a wedge-shaped strap pull-out contour, wherein said second covering leg comprises a tip and widens from the tip to partially define the wedge-shaped strap pull-out contour, and wherein the upwardly extending covering extension of said second covering leg extends at an increasing distance away from the strap channel.

9. A strapping device comprising:
a packing table;
a strapping frame at least partially above the packing table and at least partially defining a strap channel having a strap channel opening;
a pair of first strap channel flaps connected to the strapping frame, each first strap channel flap comprising a first covering leg that overlies part of the strap channel opening; and
a pair of second strap channel flaps connected to the strapping frame adjacent to the pair of first strap channel flaps, each second strap channel flap comprising a second covering leg that overlies part of the strap channel opening, wherein each second covering leg overlies approximately half of a respective one of the first covering legs of the pair of first strap channel flaps,
wherein each first strap channel flap is movable independently of each second strap channel flap between an open position and a closed position.

10. The strapping device of claim 9 , wherein one of the second covering legs of the pair of second strap channel flaps partially defines a wedge-shaped strap pull-out contour.

11. The strapping device of claim 9 , wherein each of the first covering legs of the pair of first strap channel flaps partially defines a first wedge-shaped strap pull-out contour, and wherein each of the second covering legs of the pair of second strap channel flaps partially defines a second wedge-shaped strap pull-out contour.

12. The strapping device of claim 9 , wherein one of the second covering legs of the pair of second strap channel flaps partially defines a wedge-shaped strap pull-out contour, and said second covering leg comprises a tip and widens from the tip to partially define the wedge-shaped strap pull-out contour.

13. The strapping device of claim 9 , wherein one of the second covering legs of the pair of second strap channel flaps comprises an upwardly extending covering extension.

14. The strapping device of claim 9 , wherein one of the second covering legs of the pair of second strap channel flaps comprises an upwardly extending covering extension that extends at an increasing distance away from the strap channel.

15. The strapping device of claim 9 , wherein each of the first covering legs of the pair of first strap channel flaps comprises an upwardly extending covering extension, and wherein each of the second covering legs of the pair of second strap channel flaps comprises an upwardly extending covering extension.

16. The strapping device of claim 9 , wherein each second covering leg of the pair of second strap channel flaps overlies a parting joint between the first strap channel flap and the second strap channel flap, respectively.

17. The strapping device of claim 9 , wherein one of the second covering legs of the pair of second strap channel flaps partially defines a wedge-shaped strap pull-out contour, wherein said second covering leg comprises a tip and widens from the tip to partially define the wedge-shaped strap pull-out contour, and wherein said second covering leg comprises an upwardly extending covering extension that extends at an increasing distance away from the strap channel.
