摘要：
An apparatus and process for producing a non-woven fabric or mat, wherein a downwardly advancing sheet of polymeric filaments is produced by a melt spinning device, and a draw-off device serves to withdraw the sheet from the spinning device and advance the sheet into a collecting gap which is formed by two feed rollers which are positioned a short distance above a perforated support. In order to obtain a desired configuration on both surfaces of the web, the collecting gap is extended by two opposing feed belts which cooperate with the feed rollers to shape the sheet upstream of the perforated support.
