Abstract

A device for shaping the gable surfaces of packages with a slanted gable is shown and described, including: a conveyor system with cells fixed to it to receive the packages, at least one gable folder to fold a fin seam in the gable region of the packages and at least two ear folders to fold ears in the gable region of the packages. In order to enable rapid and reliable shaping of the gable even in packages with slanted gables, it is proposed that both the gable folder and the ear folders be mounted movably relative to the conveyor system and the packages to be transported therewith. A method for shaping the gable surfaces of packages with a slanted gable is also shown and described.

First claim

The invention claimed is:

1. A device for the shaping of gable surfaces of packages with a slanted gable, comprising:
a conveyor system comprising cells for receiving the packages,
at least one gable folder for folding a fin seam in a gable region of the packages,
at least two ear folders for folding ears in the gable region of the packages,
wherein both the gable folder and the ear folders are mounted movably relative to the conveyor system and the packages transported by said conveyor system, and the at least one gable folder is mounted movably in one plane and has at least a two-dimensional mobility, and
wherein the at least one gable folder is mounted movably such that it can fold the fin seam in the gable region of the packages forward in the direction of transport of the packages.

2. The device according to claim 1 , wherein the at least one gable folder is mounted movably in a plane formed by the direction of transport and the vertical direction of the packages.

3. The device according to claim 1 , wherein the at least two ear folders are mounted movably in a plane formed by the vertical direction and the transverse direction of the packages.

4. The device according to claim 1 , wherein the at least one gable folder is arranged between the at least two ear folders.

5. The device according to claim 1 , comprising at least two gable folders for folding a fin seam in the gable region of the packages, and at least four ear folders for folding ears in the gable region of the packages, wherein one gable folder and two ear folders form a unit for processing a package in each case.

6. The device according to claim 5 , wherein all of the gable folders are adjacent to one another and connected to one another, and in that all ear folders are adjacent to one another and connected to one another.

7. A method for the shaping gable surfaces of packages with a slanted gable, comprising:
providing packages comprising gables that can be slanted,
folding of a fin seam in a gable region of the packages forward in the direction of transport by means of a gable folder, and
folding at least one ear in the gable region of the package by means of two ear folders,
wherein both the gable folder and the ear folders are moved relative to a conveyor system and the packages are transported using said conveyor system, and wherein at least one of the following is provided:
the fin seam on the slanted gable is arranged transverse to the direction of transport of the packages, or the slanted gables rise in the direction of transport of the package.

8. The method according to claim 7 , wherein the conveyor system comprises fixed cells.

9. The method according to claim 7 , wherein the packages are moved intermittently.

10. The method according to claim 7 , wherein the packages are still during the folding of the fin seams and the folding of the ears.

11. The method according to claim 7 , wherein the folding of the fin seams is carried out before the folding of the ears.

12. The method according to claim 7 , wherein there is an overlap in terms of the time at which the folding of the fin seams and the folding of the ears are carried out.

13. The method according to claim 7 , wherein the gable folder moves the fin seam in the gable region of the packages in the direction of transport of the packages.

14. The method according to claim 7 , wherein the gable surfaces of at least two packages are shaped simultaneously.
