Abstract
A highly compressed covering material is fabricated by pressing a lumpy plastics material or plastics pre-product. The plastics material or plastics pre-product is thereby fed into a double-belt press by continuously and dosedly feeding the plastics material or plastics pre-product into a region formed by lateral delimiting elements at the lower belt of the double-belt press. The continuous pressing to form the highly compressed covering material is accomplished there during heating and with increasing pressure.
