Abstract (en)

[origin: WO2006032517A1] The invention relates to a device for stacking synthetic fibres to form a nonwoven. The fibres are transported through a take-off nozzle by means of an air stream in the direction of a stacking belt. The device is provided with a guide duct for guiding fibres from the take-off nozzle to the stacking belt, said duct having a mobile retaining flap on one end of a longitudinal side that faces the stacking belt. To obtain a stacking area on the stacking belt that is separate from the environment as the position of the retaining flap is modified, the retaining flap is formed by a support and an elastic sealing lip, which is held in frictional contact with the stacking belt.
