ABSTRACT:
There is provided a brushing apparatus useful for cleaning of PC Cards, comprising at least one pair of coaxially arranged brushes. The brushes are rotated and the bristle surfaces of a pair of brushes face each other. The PC cards are fed in a plane between the opposing brushes. The pairs of brushes may be arranged in one or more rows. In the case of one row, the row may extend at an angle to the transport direction of the PC cards. In the case of two parallel rows, the pairs of brushes of one row may be displaced longitudinally half a brush diameter, relative to the pairs of brushes of the other row.
