Abrégé
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Laminats mit zumindest einer Pulverschicht, wobei die Pulverschicht kontinuierlich hergestellt wird. Auf eine erste Lage 167 wird ein Bindemittel 164 zumindest streifenförmig aufgetragen, wobei das Bindemittel 164 quer zu einer Bewegungsrichtung der ersten Lage 167 zwischen getrennt voneinander angeordneten Pulverschichten zum Liegen kommt. Eine zweite Lage 169 wird kontinuierlich der ersten Lage 165 zugeführt, so dass die erste 165 und die zweite 169 Lage die Pulverschicht 168 umgeben. Weiterhin betrifft die Erfindung eine Vorrichtung zur kontinuierlichen Herstellung eines Laminats.
(EN)
The invention relates to a method for the production of a laminate with at least one powder layer, whereby said powder layer is produced continuously. An adhesive (164) is applied at least in strips on a first layer (167), whereby the adhesive (164) is applied transverse to a direction of movement of the first layer (167), between layers of powder arranged separately from each other. A second layer (169) is continuously introduced to the first layer (165) such that the first (165) and the second (169) layers surround the powder layer (168). The invention further relates to a device for the continuous production of a laminate.
(FR)
La présente invention concerne un procédé de production d'un stratifié comprenant au moins une couche de poudre étant produite de manière continue. Un liant (164) est appliqué sur une première couche (167), au moins sous forme de bandes, ledit liant (164) étant disposé transversalement à un sens de mouvement de la première couche (167) entre des couches de poudre séparées les unes des autres. Une seconde couche (169) est continuellement déposée sur la première couche (165), de manière à ce que la première couche (165) et la seconde couche (169) entourent la couche de poudre (168). L'invention concerne en outre un dispositif permettant de produire un stratifié en continu.
