Zusammenfassung:A method and an apparatus for manufacturing a multi-layer fabric including at least one fibre layer formed by airlaying combined with at least one further layer which is formed by different technologies, including carding, spunlacing, meitblowing, spunbonding, or airlaying, or combined with one or more films. The airforming is performed on a separate formerwire which is applied vacuum via a suction box disposed opposite to a formerhead, and where the airformed fibre layer is transferred to a conveyor wire for joining with a further layer. Edge trimming is performed at least on the airformed layer before it is joined with one or more other layers for forming the multi-layered fabric. Scrap from edge trimming and exhaust from the suction box is returned to the formerhead.
