Abstract

A device to make an adjustable amount of particles in a gas flow so that these can easily be transported by the gas flow through a tube or another channel (19) from a container (1) to an orifice, at which for example an applying device can be arranged. The device is primarily aimed for particles in the shape of short fibres of synthetic material, such as for example polyamide with a length of less than five millimetres, but can be used for example for particles that form a powder. By that the amount of fibres or other particles in an easy way can be adjusted, an exact adjustment of the density of a layer that is applied can be done, at which an even layer is made and unnecessary material waste is avoided. The most important characteristic of the device is a perforated part (3) in which a rotating part (4) is arranged so that it reaches towards the perforated part and that a gas flow is arranged to sweep over or around the perforated part (3) so that it leads away the particles, that from the container is moved through the perforated part.
