摘要:
A device is described for producing a fibre product by laying down melt-spun fibres onto a laydown belt. In the laydown belt, a spinning device is associated on a top side and a suction-extraction device is associated on a bottom side, wherein the suction-extraction device has a movable suction chamber which interacts with the spinning device in order to lay down the fibres on the laydown belt. In order for it to be possible to generate a uniform suction flow in every position of the suction chamber, according to the invention 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.

The invention relates to a method and a device for melt-blowing, forming and plaiting finite fibres to produce a fibrous nonwoven. Here, the fibre streams which are produced by a melt-blowing die and a hot air flow are blown into a forming gap of a forming element, wherein the fibres are joined together within the forming gap to produce a fibre composite. In order to influence the filling and the forming of the fibres within the forming gap directly below the melt-blowing die, according to the invention the fibres are freely guided substantially vertically from the melt-blowing die as far as the forming gap via an adjustable blowing section, wherein the adjustability of the blowing section lies in the range from 100 mm to 2000 mm. In this way, both very fine fibres and coarse fibres can advantageously be formed to produce a loose fibre composite.
