Disclosed are a device and a method for compacting a continuously conveyed fiber composite (V) by means of heat (W) impingement. A heated treatment medium (L) is blasted towards the fiber composite (V) by means of at least one nozzle arrangement (2a, 2b). Said nozzle arrangement (2a, 2b) comprises a plurality of adjacent blasting nozzles (4) which are disposed at a distance (a) from each other. An intermediate space (5) is formed between two adjacent nozzles (4). Said intermediate space (5) between blasting nozzles (4) is essentially closed to the fiber composite (V) counter to the conveying path (F) such that an overpressure (P) can be created in a pressure chamber (6) located between the nozzle arrangement and the surface (O) of the fiber composite (V), whereby the treatment medium (L) can be blasted through the entire thickness of the fiber composite (V) even when said fiber composite has a great thickness.
L'invention concerne un dispositif et un procédé destinés à consolider sous l'action de la chaleur (W), un composite fibre (V) alimenté en continu. A cet effet, un milieu de traitement chauffé (L) est soufflé, au moyen d'au moins un système de tuyères (2a, 2b), à l'encontre du composite fibre (V). Le système de tuyères (2a, 2b) présente une pluralité de tuyères de soufflage (4) disposées les unes à côté des autres, à distance (a) entre elles. Un espace intermédiaire (5) est formé entre les tuyères voisines (5). L'espace intermédiaire (5) entre tuyères voisines (4) est essentiellement fermé à l'encontre du trajet d'acheminement (F) du composite fibre, de sorte qu'il se forme une surpression (P) dans un espace de pression (6), entre le système de tuyères et la surface (O) du composite fibre (V). De cette façon, même pour un composite épais, le milieu de traitement (L) peut être soufflé à travers toute l'épaisseur du composite fibre (L).
