14 Claims

1. An annular discharge device for discharging a gluing composition onto mineral fibres, comprising at least one distribution circuit for distributing said gluing composition and a plurality of spray nozzles fluidically connected with the distribution circuit and distributed over a perimeter of the annular discharge device for discharging the gluing composition onto the fibres intended to pass inside the annular discharge device defined by an axis of revolution, each spray nozzle being oriented towards an interior of the annular discharge device with an angle of inclination determined in relation to a plane of revolution of the annular discharge device, wherein each spray nozzle of the plurality of spray nozzles is adjacent to spray nozzles whose orientation with respect to the plane of revolution of the annular discharge device is different from its own such that two consecutive spray nozzles of the plurality of spray nozzles arranged consecutively on the perimeter of the annular discharge device have a different angle of inclination with respect to one another.
