Abstract
The invention relates to an apparatus for the separation of edge trimmings, in connection with a pulper. The upper portion of the jacket of the pulper (1) serves as a jacket of a first cyclone (5), a second cyclone (8) opposite in direction being provided within said cyclone (5). When the air flow enters the second cyclone and the direction thereof is reversed, it is essentially retarded, whereby also light paper particles fall into the stock contained in the pulper. The object is to provide an efficient device for the separation of edge trimmings, which device does not spread dust in the surroundings.
