## Abstract

A device for the production of padding products has a product guide, a product drive along a drive axis (Y), and a product crumpling device. The guide is attached to a part of the device mechanically at at least a part of its section and is held on another part of the device by magnetic repulsion forces.

## Claims

### Claim 1

A device for the production of stuffing product comprising a product guide means, a product drive means along a drive axis (Y), a means of crumpling the product, wherein the guide means is mechanically attached to a part of the device by at least a part of a section of the guide means, and, is held onto another part of the device by magnetic repulsion forces on another part of a section of the guide means.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the part of the section of the guide means that is held in place by magnetic repulsion forces is held onto a magnetic support, so as to form a space between the guide means and the magnetic support.

### Claim 3 (depends on 2)

A device according to claim 2, wherein the guide means and the magnetic support each comprise a permanent magnet and/or an electromagnet arranged two by two opposite each other.

### Claim 4 (depends on 2)

A device according to claim 2, wherein at least a substantial portion of one end of the guide means is free and held in place by magnetic repulsion forces to magnetic support.

### Claim 5 (depends on 2)

A device according to claim 2, wherein the magnetic support comprises a bar or two bars arranged opposite from on either side of the guide means.

### Claim 6 (depends on 2)

A device according to claim 2, wherein the magnetic support comprises an enclosure or a portion of enclosure surrounding a part of the guide means.

### Claim 7 (depends on 1)

A device according to claim 1, wherein the guide means is mechanically attached to a shaping block as a supply means, placed upstream from the drive means.

### Claim 8 (depends on 7)

A device according to claim 7, wherein the shaping block comprises two slots each designed to have a product pass through the shaping block or one slot whose ends overlap and which is designed to feed a crumpled product onto itself.

### Claim 9 (depends on 8)

A device according to claim 8, wherein the guide means is mechanically fastened between the two slots of the shaping block or between the one slot of the shaping block whose ends overlap.

### Claim 10 (depends on 1)

A device according to claim 1, wherein that at least one part of the section of the guide means is mechanically attached to a means of crumpling or to a drive means.
