ABSTRACT:
The subject of the invention is a unit for manufacturing felts (6) which are formed from crosslinked mineral fibers, comprising at least one pair of conveyors formed by a lower conveyor (11) and an upper conveyor (12) which are placed opposite each other and intended to compress said felt (6) in at least one direction, a means (13) for heat treating the felt (6) after it has passed through the conveyors (11, 12) comprising at least one means (14) placed between the conveyors (11, 12) and the heat treatment means (13), intended to prevent decompression of the felt (6) in this region, said means comprising at least one cam (14) having a profile suitable for keeping a constant and minimum distance between the conveyors (11, 12) and the heat treatment means (13), and in that at least one of the conveyors is rigidly connected to one element of the heat treatment means (13).
