ABSTRACT:
A method of heating a fleece comprises supporting the fleece on a perforate fleece carrier and passing a heated gas through the fleece and fleece carrier, preferably in that sequence to assist compaction of the fleece. Apparatus for performing this method comprises two chambers between which the fleece is passed on the carrier, the chambers being maintained at different pressures by a fan to create the flow through the fleece and through a radiator for heating the gas. The gas may be recirculated and may be filtered and/or augmented by a further supply. A roller at the exit end of the chambers compresses the heated fleece, preferably from above. The fleece carrier may be preheated upstream of the heating station, for example by induction heating in the case of a metal fleece carrier. A freely running roller having adjustable height rests on the fleece and seals the entry to the heating station.
