Double belt press and method for continuously pressing a wood-based mat to form a wood-based panel or a laminate

摘要

The invention relates to a double belt press (1) for continuously pressing a wood material mat (2) to form a wood material panel (3) and / or a laminate with two press belts (6, 7) endlessly surrounding at least two deflection means forming a press nip (5), wherein the press belts (6, 7) in each case have an outer side coming into contact with the wood material mat (2) and / or the laminate and an inner side which does not come into contact with the wood material mat (2) and / or the laminate. Thus, the wood-based panels can be made more reliable and with a higher surface quality, it is provided that at least one from the outside of at least one press belt (6, 7) outside the press nip (5) at least a portion of the press residues (16) erosive, in particular the outside of Pressbands (6, 7) polishing, polishing device (17) is provided.
