Abstract
A device is described for producing a fiber product by laying down melt-spun fibers onto a laydown belt. A spinning device is associated with a top side of the laydown belt and a suction-extraction device is associated with the bottom side. A vacuum device has a movable suction chamber which interacts with the spinning device in order to lay down the fibers on the laydown belt. To generate a uniform suction flow in every position of the suction chamber, the suction chamber is formed from a stationary bottom box and a movable top box which are coupled to one another in a pressure-tight manner.
