## Abstract

A device for the production of padding product, including a product guide, a product drive along a drive axis (Y), a device for crumpling the product, which is designed to be alternatively, by a back-and-forth motion, in a position that constrains the product and a product release position.

## Claims

### Claim 1

A device for production of stuffing product, comprising a product guide means, a product drive means along a drive axis (Y), and a means of crumpling the product, where the means of crumpling the product is designed to be alternatively, by a back-and-forth motion, in a position that constrains the product and a release position of the product, the release position is a retracted position, a withdrawn position of the means of crumpling, wherein the back-and-forth motion of the means of crumpling the product is controlled by a control cell.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the means of crumpling the product is controlled by a motor connected to an engine control board that is controlled by a Program Logic Controller (PLC).

### Claim 3 (depends on 1)

The device according to claim 1, wherein the means of crumpling the product is moveable along a vertical axis (Z) perpendicular to drive axis (Y).

### Claim 4 (depends on 1)

The device according to claim 1, wherein the means of crumpling the product is moveable along drive axis (Y).

### Claim 5 (depends on 1)

The device according to claim 1, wherein the means of crumpling the product comprises a series of crumpling flaps or crumpling rods distributed along a transverse axis (X) perpendicular to drive axis (Y).

### Claim 6 (depends on 1)

The device according to claim 1, wherein the drive means is configured so that it displaces one sheet of paper in both directions along drive axis (Y).

### Claim 7 (depends on 1)

The device according to claim 1, wherein the guide means comprises crumpling guides that extend in the direction of drive axis (Y).

### Claim 8 (depends on 7)

The device according to claim 7, wherein crumpling guides are attached at one end of the crumpling guides to a shaping block and are free at another end of the crumpling guides.

### Claim 9 (depends on 7)

The device according to claim 7, wherein one of said crumpling guides is arranged facing the other of said crumpling guides and upstream of the means of crumpling the product.
