Abstract: The present invention relates to a method and an arrangement for representing the characteristics of an object with a measuring system, in which either the measuring system or the object is designed to move in relation to one another in a predefined direction of movement. The object preferably is designed to move in relation to the measuring system. At least one light source is designed to illuminate the object with a light which is incident upon the object and has a limited extension in the direction of movement. An imaging sensor, which is arranged on the same side of the object as the light source is designed to pick up light reflected from the object and to convert this into electrical charges. An image-processing unit is furthermore designed to create a digital representation of the object from said electrical charges.

Abstract: A mineral wool centrifuge which comprises a rotatable centrifuge wheel (3) for the defibration of a molten mineral material to be passed on to said centrifuge wheel; a driving motor (2) for the rotation of the centrifuge wheel; a blowing air nozzle/blowing air nozzles (6) for applying blowing air to the periphery of the centrifuge wheel for separating mineral fibres from the molten mineral material; and means (9a, 9b, 17) for applying a binder to the mineral fibres separated from the periphery of the centrifuge wheel.
