Abstract (en)

Before the fiber batt (3) is wound up into a roll, it is compressed (31) and then released (33) in a direction at right angles to the surfaces (21,22) to make it more elastic. At least the surface forming the outside of the roll is treated. Variants of the process also apply some compression and decompression in an axial direction by changing the angle of the conveyors (13 to 17, 23 to 27). An Independent claim is also included for a rolling station incorporating a compression (31) and decompression (33) zone. The action can be carried out by angled conveyors (13 to 17, 23 to 27) or alternatively by rollers or hydraulically activated plungers. The rate of deformation is controlled and can include steam treatment.

Abstract (de)

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung einer Dämmstoffbahn, insbesondere eines Dämmfilzes bzw. hieraus vereinzelbaren Dämmplatten aus Steinwolle, bei dem ein Faservlies auf einer Fördereinrichtung einer Aufrollstation zugeführt wird, in der das Faservlies zu einem Wickel aufgewickelt wird, wobei das Faservlies im Wickel komprimiert ist. Um eine gleich-mäßige Elastifizierung des Faservlieses zu erzielen, so daß das Faservlies auch bei großer Dichte schonend aufgerollt werden kann, ist vorgesehen, daß das Faservlies vor der Aufrollstation einer Kompressions- und Dekompressionsvorrichtung zugeführt wird, in der das Faservlies im wesentlichen in Richtung der Flächennormalen zumindest seiner im Wickel außenliegenden großen Oberfläche komprimiert und anschließend dekomprimiert wird, um das Faservlies zu elastifizieren, wobei die Kompression und die Dekompression kontrolliert erfolgt. <IMAGE>
