Method for producing paper sacks and paper sacks

Abstract

The invention relates to a method for producing paper sacks comprising the following steps: providing a tube section (2) that comprises at least a first paper layer (4) and a second paper layer (6), wherein the first tube section (2) has a first end (8) and an opposite second end (10), and a longitudinal extension which extends from the first end (8) to the second end (10), and the first end (8) is formed by the first paper layer (4) and the second end (10) by the second paper layer (6), forming a first base (12) at the first end (8) and forming a second base (14) at the second end (10).

Claims

1. A method for producing paper sacks, comprising: providing a tube section that comprises at least a first paper layer and a second paper layer, wherein the tube section comprises a first end and a second end, and a longitudinal extension which extends from the first end to the second end, and the first end is formed by the first paper layer and the second end is formed by the second paper layer, forming a first base at the first end of the tube section, and forming a second base at the second end of the tube section, wherein the first base is not formed with paper of the second paper layer, and the second base is not formed with paper of the first paper layer.

2. The method according to claim 1, wherein the first paper layer and the second paper layer are not connected to each other.

3. The method according to claim 1 wherein the first base and the second base are formed at the same time.

4. The method according to claim 1 wherein the first paper layer and the second paper layer each have an expansion along a longitudinal extension in a direction of longitudinal extension that is equivalent before the first base and the second base are formed.

5. The method according to claim 1 wherein the first paper layer and the second paper layer are separated from each other after the first base and the second base are formed.

6. The method according to claim 5, wherein the first paper layer and the second paper layer are separated from each other by being pulled apart along a longitudinal extension.

7. The method according to claim 1 wherein the tube section comprises the first paper layer and one or more additional first paper layers, and/or comprises the second paper layer and one or more additional second paper layers.

8. The method according to claim 7, wherein the first paper layer and the one or more additional first paper layers are joined together and/or wherein the second paper layer and the one or more additional second paper layers are joined together.

9. A system, comprising two paper sacks, wherein each of the two paper sacks are produced by a method according to claim 1, wherein the two paper sacks each have an opening and a base, and wherein a first paper sack of the two paper sacks protrudes with its opening into a second paper sack of the two paper sacks.

Description

(1) In the following, an embodiment example of the invention will be explained in more detail with the aid of the accompanying figures. They show:

(2) FIGS. 1 to 3schematic representations of various stages during a method according to an embodiment example of the present invention.

(3) FIG. 1 depicts a tube section 2 that comprises a first paper layer 4 and a second paper layer 6. The first paper layer 4 is arranged inside the second paper layer 6, which is depicted by the dashed line. In FIG. 1, the first paper layer protrudes to the left beyond the second paper layer 6, where it forms a first end 8. In FIG. 1, the second paper layer 6 protrudes to the right beyond the first paper layer 4, where it forms a second end 10.

(4) FIG. 2 shows the situation after a first base 12 has been formed at the first end 8 and a second base 14 has been formed at the second end 10. The double arrow 16 illustrates that the first paper layer 4 and the second paper layer 6 can be moved freely against each other in these directions.

(5) In FIG. 3 the two paper layers 4, 6 have been moved against each other in the direction of the double arrows from FIG. 2. The first paper layer forms the first paper sack and the second paper layer 6 forms a second paper sack.
