Dried fibres which are designated for the production of fibre boards are supplied to a fibre roller ( 17 ) from a metering device through a feed chute ( 10 ) which is subjected to negative pressure, which fibre roller is provided on its surface with a plurality of pins ( 18 ) and rotates in such a manner that the fibres ( 14 ) are deflected by the pins ( 18 ), are directed along a chute section ( 22 ) defined by means of a partial section ( 20 ) of the periphery of the fibre roller ( 17 ) and an opposite-lying wall ( 21 ) and gluing means and said fibres are accelerated to approximately the peripheral speed of the fibre roller ( 17 ) by means of the pins ( 18 ) and an air flow generated by said pins. The fibres ( 36 ) lie against a section of the wall and are glued in the region of or adjacent to one end of the wall section and exit at an outlet orifice ( 23 ) of the chute section ( 22 ). In the case of an alternative process, after exiting the chute section substantially horizontally the fibres are deflected in an upward or downward direction and are glued in this region by means of at least one spray nozzle.
