Zusammenfassung:	A system (10) for laminating a plurality of veneer layers (14, 18) is disclosed. The system (10) comprises a base veneer layer roll (12) carrying a base veneer layer (14) and at least one additional roll (16) carrying at least one additional veneer layer (18) that is to be laminated to the base veneer layer (14). Guiding means (24, 28) is provided for guiding the two layers (14, 18) towards each other, with a pair of adjacent laminating rollers (30, 32) being arranged to receive the base veneer layer (14) and the additional veneer layer (18) therebetween, so as to continuously laminate the two layers (14, 18) as they move through the laminating rollers (30, 32). Preferably, the additional veneer layer (18) is impregnated with heat-activatable glue, with the system (10) further including a bank of heating elements (40) arranged to activate the glue on the additional veneer layer (18). L'invention concerne un système (10) pour laminer une pluralité de couches de vernis (14, 18). Ce système comprend un rouleau de couche de vernis de base (12) portant une couche de vernis de base (14) et au moins un rouleau supplémentaire (16) portant au moins une couche de vernis supplémentaire (18) à laminer sur la couche de vernis de base (14). Un moyen de guidage (24, 28) permet de guider les deux couches (14, 18) l'une vers l'autre, une paire de rouleaux de laminage adjacents (30, 32) étant agencés pour recevoir la couche de vernis de base (14) et la couche de vernis supplémentaire (18) entre ces rouleaux, de sorte à laminer de manière continue les deux couches (14, 18), alors qu'elles se déplacent à travers les rouleaux de laminage (30, 32). De préférence, la couche de vernis supplémentaire (18) est imprégnée de colle thermiquement activable, le système (10) comprenant également un ensemble d'éléments de chauffage (40) agencé pour activer la colle sur la couche de vernis supplémentaire (18).
