## Abstract

The invention relates to a method for structuring a press belt (5) made of metal, which has surface areas having three-dimensional embossed structures (6) to be transferred to decorative panels, and a coating is applied to an outer face of the press belt (5) and the embossed structures (6) are then produced by abrading material from or applying material to uncoated regions of the press belt (5), and the application of the coating is carried out by means of a digitally controlled printing method in which the coating is applied in droplet form, wherein before the press belts (5) are structured, the length and width of the embossed structures (6) are determined, taking into account an anticipated elongation of the press belt (5) in an operative state.

## Claims

### Claim 1

Method for structuring a press belt made of metal, which has surface areas having three-dimensional embossed structures to be transferred to decorative panels, and a coating is applied to an outer face of the press belt and the embossed structures are then produced by abrading material from or applying material to uncoated regions of the press belt, and the application of the coating is carried out via a digitally controlled printing method in which the coating is applied in droplet form,
wherein before the press belt is structured, an elongation of the press belt in an operative state is calculated and a desired size of the embossed structures in the operative state is determined,
wherein length and width of the embossed structures are then scaled in such a way that the desired size of the embossed structures is assumed in the operative state,
wherein the elongation of the press belt is calculated on the basis of an effective belt thickness of the press belt, and
wherein the effective belt thickness corresponds to a value for a minimum distance of the belt outer face from the belt inner face of the press belt after producing the embossed structure.

### Claim 2 (depends on 1)

Method according to claim 1, wherein two consecutive embossed structures in the longitudinal direction of the press belt are separated from one another by a surface portion of the press belt.

### Claim 3 (depends on 2)

Method according to claim 2, wherein an intermediate structure which is different from the embossed structures is imparted to the surface portion of the press belt lying between two embossed structures.

### Claim 4 (depends on 1)

Method according to claim 1, wherein an odd number of embossed structures is imparted to the press belt.
