ABSTRACT:
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.
