Abstract
The invention relates to a device for depositing synthetic fibers to form a non-woven web. The fibers are transported through a take-off nozzle by means of an air stream in the direction of a depositing belt. The device is provided with a guide duct for guiding fibers from the take-off nozzle to the depositing belt, said duct having a mobile retaining flap on one end of a longitudinal side that faces the depositing belt. To obtain a depositing area on the depositing 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 depositing belt.
