Abstract
A laminate panel and a method to produce a laminate panel, includes the steps of: forming a stack; pressing the stack using a pressing device, the pressing device comprising a first press element and a second press element; wherein the second press element comprises an upper surface which faces and contacts the stack, wherein the upper surface comprises a structure, the structure having a base surface and indentations which form lower areas relative to the base surface, wherein maximum height differences between the lower areas and the base surface are at least 100 μm.

A method to produce a laminate panel, for example a laminate floor panel, comprising the steps of:
- forming a stack comprising a board, a base top layer and a base balancing layer,
- wherein said board is located between said base top layer and said base balancing layer,
- wherein said board is a lignocellulose-based board such as a wood fiber board or a particle board, and
- wherein said base top layer comprises synthetic material and said base balancing layer comprises synthetic material;
- pressing the stack using a pressing device, said pressing device comprising at least a first press element and at least a second press element,
- wherein the stack is pressed between said first and second press element in such a way that the first press element contacts the base top layer, the second press element contacts the base balancing layer, the base top layer adheres to the board, the base balancing layer adheres to the board and a pressed stack with the base top layer, the board and the base balancing layer interconnected, is formed;
- wherein the second press element comprises an upper surface which faces and contacts the base balancing layer,
- wherein said upper surface comprises a structure, said structure having a base surface and indentations which form lower areas relative to said base surface,
- wherein maximum height differences between said lower areas and the base surface are located between 100 μm and 350 μm.
A laminate panel, comprising, seen from the top to the bottom, a top layer comprising synthetic material, a substrate, being a lignocellulose based substrate, and a balancing layer comprising synthetic material,
- wherein the balancing layer comprises an outer surface opposite said substrate, said outer surface comprising a structure having a base bottom surface and individual protrusions which protrude with regard to said base bottom surface,
- wherein maximum differences in height between said base bottom surface and said protrusions are located between 100 μm and 350 μm.
