ABSTRACT:
A device for the treatment of sheet materials comprises two cylindrical rolls from a magneto-conducting material and electromagnets which are positioned relative to these rolls so that they form, together with the electromagnets, a single magnetic system, wherein one roll has one polarity and the other roll has an opposite polarity. Under the effect of this field the particles of an abrasive material are orientated and retained on the external surface of the rolls, forming a brush, as a result of which a sheet material, when passing through a gap, is subject to treatment from both sides.
