VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG VON MINERALFASERFILZEN

摘要

A unit and process of manufacturing felts formed from crosslinked mineral fibers. The unit includes at least one pair of conveyors formed by a lower conveyor and an upper conveyor placed opposite each other and configured to compress the felt in at least one direction. A heat treating device heat treats the felt after the felt has passed through the conveyors. At least one mechanism is placed in a region between the conveyors and the heat treatment device, to prevent decompression of the felt in this region. The mechanism includes at least one cam having a profile suitable for keeping a constant and minimum distance between the conveyors and the heat treatment device, and at least one of the conveyors is rigidly connected to one element of the heat treatment device.
