Abstract

A method for making a floor or wall panel has a foamed polymer core. A foamable polymer powder is foamed between two conveyor belts in the forming zone of a steel belt press. The sum of the thicknesses of the two conveyor belts and the total thickness of the layers at the entrance of the steel belt press is less than or equal to the opening of the steel belt press at the entrance of the steel belt press. The sum of the thicknesses of the two conveyor belts and the total thickness of the substrate at the outlet of the steel belt press is equal to the opening of the steel belt press at the outlet of the steel belt press and greater than the sum of the thicknesses of the two conveyor belts and the total thickness of the layers at the entrance of the steel belt press.
