Abstract
A magnet bar for exerting an attracting force on a doctor, which is arranged above the magnet bar, of a screen-printing or coating device comprises an elongate top plate and an elongate magnet carrier which extends below and substantially parallel to the top plate and on which permanent magnets are arranged next to one another in the longitudinal direction. The distance between the magnet carrier and the top plate can be adjusted by means of a displaceable adjustment member, which is arranged below the magnet carrier, in order to adjust the magnitude of the attracting force. The magnet carrier is supported freely on the adjustment member and the weight of the magnet carrier with magnets or the sum of the weight of the magnet carrier with magnets and the force of at least one spring acting upon the magnet carrier in downward direction is greater than the maximum attracting force which can be exerted by the magnets on a doctor which is arranged above the magnet bar.
