  • the distance s 2 between the median plane M and a side wall 16, 17 of the first diffuser 13 is expediently 0.8 s 1 to 2.5 s 1 (s 1 corresponds to the distance of the median plane M to the side wall at the narrowest point of the first diffuser 13).
  • the distance s 3 of the median plane M to the side wall at the narrowest point of the second diffuser 14 is preferably 0.5 s 2 to 2 s 2 .
  • the distance s 4 of the median plane M to the lower edge of the side wall of the second diffuser 14 is 1 s 2 to 10 s 2 .
  • the length L 2 has a value of 1 s 2 to 15 s 2 . For the width of the ambient air inlet gap 15 different variable values are possible.
  • the aggregate of cooling chamber 2, intermediate channel 3, drawing unit 4 and laying unit 6, apart from the air intake in the cooling chamber 2 and air inlet columns on the laying unit 6 and the air inlet at the ambient air inlet gap 15 forms a closed system.
  • Fig. 4 shows a continuously moving Ablegesiebband 7 for the spunbonded nonwoven web, not shown.
  • three suction regions 18, 19, 20 are arranged one behind the other in the direction of movement of the discharge screen belt 7.
  • a Hauptabsaug Colour 19 is provided in the storage area of the spunbonded web.
  • a first suction area 18 is arranged in front of the storage area or in front of the main suction area 19.
  • a second suction region 20 is connected downstream of the main suction region 19.
  • each suction area 18, 19, 20 can be assigned a separate suction fan.
  • only a suction fan is provided and that the respective suction conditions in the suction areas 18, 19, 20 are adjusted by means of adjusting and throttle bodies.
  • the first suction region 18 is bounded by the walls 21 and 22.
  • the second suction region 20 is bounded by the walls 23 and 24.
  • the walls 22, 23 of the Hauptabsaug Schemees 19 preferably and in the embodiment form a nozzle contour.
  • the suction speed in Hauptabsaug Scheme 19 is advantageously higher than the suction speeds in the first suction 18 and the second suction 20. It is within the scope of the invention that the suction in the Feldabsaug Scheme 19 regardless of the suction in the first suction 18 and the second suction 20 controlled / or regulated.
  • the task of the first suction area 18 is to remove the quantities of air supplied with the discharge screen belt 7 and to align the flow vectors at the border to the main suction area 19 orthogonally with respect to the discharge screen belt 7.
  • the first suction area 18 serves to reliably hold filaments that have already been deposited here on the reject screen belt 7.
  • the Hauptabsaug Colour 19 entrained with the filaments air can flow freely, so that the spunbonded can be stored reliable.
  • at least part of the second suction region 20 in the transport direction of the Ablegesiebbandes 7 in front of the pressure roller pair 33 is arranged.
