Abstract (en)
[origin: WO2020156837A1] The invention relates to a device and a method having a first and a second zone (Z1, Z2) for producing insulating or acoustic panels from a pressed material mat (2) which consists at least partially of lignocellulose particles coated with binders, the first zone (Z1) being designed for heating and/or compressing the pressed material mat, and the second zone (Z2) being designed for curing the pressed material mat with the aid of calibration plates (3), and there being driven circulating screen bands (5a-5f) in contact with the upper and lower pressed material mat surfaces. According to the invention, to increase the production speed, at least four circulating screen bands (5a-5f) are used, at least two of which are in operative contact with the pressed material mat (2) in the region of the first zone (Z1), and at least two of which are in operative contact with the pressed material mat (2) in the region of the second zone (Z2).
