Abstract

The present invention solves the problem of controlling the amount of particles of fibres which are emitted in a nozzle from a gas flow when these are transported by the gas flow through a flexible hose or some other canal from a container. Due to the fact that the amount of fibres or other particles which are emitted can be controlled in a simple way, an accurate control of the density of a layer which is applied can be made, an even layer can be achieved and unnecessary material consumption can be avoided. The problem is solved primarily in that a gas flow containing the particles is conducted in a canal to a valve arranged where the particles are to be emitted, a second canal leads from the valve to a suction source and the vent comprises regulating means for controlling the size of the gas flows to the suction source and to the outlet of the valve. By means of this construction a continuous flow of fibres or particles can be guided towards the valve and that part which is not emitted to the nozzle is conveyed further by the suction source and is collected. By means of the above-mentioned method an application of fibres or particles in an adhesive layer, applied with, for example, melt adhesives or cold adhesives, may be guided during a course which can be continuous or intermittent.
