- the entire unit of the cooling chamber and drawing unit is designed to be closed and, except for the supply of cooling air in the cooling chamber, no further air is supplied to this unit.
- the filaments - usually from above - are introduced into the cooling chamber and it goes without saying that certain air fractions enter the cooling chamber with these filaments.
- a further air supply does not take place according to this very preferred embodiment of the invention in the aggregate of cooling chamber and drawing unit.
- the nonwoven web is guided in the conveying direction before the moistening device by at least one compacting device, in which the nonwoven web is compacted or slightly pre-consolidated.
- this compacting device therefore, only compacting or slight preconsolidation takes place and still no actual preconsolidation, as in the case of hydraulic preconsolidation or in the case of high-pressure water jet treatment or as in the case of preconsolidation with a calender.

- the lower outlet roller may also be heated.
- the upper outlet roller and the lower outlet roller expediently have the same temperature or essentially the same temperature.
- the invention is based on the finding that the use of the outlet roller or the outlet rollers increases the resistance of the nonwoven web against displacements by air movements.
- the suction region is sealed in the region of the filament deposit and so a simple and defined control of the air movements in this area becomes possible.
- the nonwoven web is pre-moistened in at least one moistening device before the preconsolidation.

- the humidifier operates at significantly lower pressures than the hydroentanglement.
- the nozzles in the moistening device can be designed more easily.
- the fluid medium / water is forced through the nonwoven web and through the Ablagesiebband in a arranged under the Ablagesiebband drain hole, preferably in a drain slot. At this at least one drain opening or at this at least one drain slot a vacuum or vacuum is suitably applied.
