ABSTRACT:
An apparatus and a process for the continuous production of mineral wool nonwovens in the nonwoven formation process on the drums of the accumulating conveyors arranged at the lower end of a chute. Several fiberization units (1, 2, 3, 4) communicate with a chute (9) for the formation of a nonwoven (14). The fibres are deposited under the influence of suction pressure onto the curved surface of the accumulating conveyor (10, 11). At least one of the drum-shaped accumulating conveyors (10) is designed to swivel around a pivot (23) essentially arranged perpendicular to the flow direction (22) of the mineral wool such and to the extent that a discharge gap (21) can be adjusted to a width corresponding to the thickness of the nonwoven (14) to be formed.
