Table for a chopper folding device and corresponding chopper folding device

1. A table for a chopper folding device comprising:

a surface for application of products to be folded, the application surface extending along an application plane, the surface having a folding opening suitable for passing the products to be folded;

at least one first guide portion disposed adjacent to the folding opening and comprising a first guide surface inclined with respect to the application plane; and

a guide suitable for urging the product to be folded towards the first guide surface and provided with a first main suction hole opening on the first guide surface.

2. The table according to claim 1 further comprising a second guide portion disposed adjacent to the folding opening and facing the first guide portion, the second guide portion comprising a second guide surface inclined with respect to the application plane; and a second main suction hole which opens on the second guide surface.

3. The table according to claim 1 wherein the table defines a front part and a rear part according to a direction of displacement of a product to be folded on the table, and that the first main suction hole is disposed in a front half of the associated guide portion.

4. The table according to claim 3 further comprising for the first main suction hole, a main air duct opening in the first main suction hole and an auxiliary air duct opening in the auxiliary suction hole, and that a location of the mouth of the main air duct and the auxiliary air duct are disposed at ends of the first main suction hole and auxiliary suction hole directed towards one another.

5. The table according to claim 1 wherein at least one first guide portion comprises an auxiliary suction hole, and that the auxiliary suction hole is offset from the first main suction hole.

6. The table according to claim 5 wherein the auxiliary suction hole has a length less than the length of the main first suction hole.

7. The table according to claim 1 wherein the first main suction hole is situated at a location of the first guide surface having an inclination of less than 45° relative to the application surface.

8. The table according to claim 1 wherein the first guide surface has a curved cross-section.

9. The table according to claim 8 wherein the curved cross section is in the shape of an arc of a circle.

10. The table according to claim 9 further comprising an application vacuum device connected to the holes of each of the groups of holes.

11. The table according to claim 1 wherein the application surface has two halves separated by a plane of separation, and that the table has a first group of suction and application holes extending over a first zone of the application surface and a second group of suction and application holes extending over a second zone of the application surface, that the second zone is disposed on the same half of the application surface as the first zone, and that each group of application holes is provided with an individual suction connector.

12. The table according to claim 11 wherein each group of application holes includes a vacuum chamber, the application holes of the associated group of holes opening into the vacuum chamber and the associated suction connector opening into the vacuum chamber.

13. The table according to claim 11 wherein the first zone and the second zone are offset from one another in the longitudinal direction.

14. The table according to claim 11 wherein the first zone and the second zone are offset from one another in the transverse direction.

15. The table according to claim 1 further comprising a vacuum device connected to the first main suction hole.

16. A chopper folding device comprising:

a chopper folding blade;

two folding rollers; and

a chopper folding table as recited in claim 1 .
