Abstract
A magnetic beam for a roller squeegee of a rotary screen printing installation including an elongated upper plate on the underside of which a number of magnet coils are attached. The upper plate is connected to a lower container which extends over virtually the entire length of the upper plate and surrounds the magnet coils. The lower container has a projecting journal at each end which rests on a vertically adjustable stop connected to the frame of the printing installation. In order to avoid warping of the magnetic beam as a result of temperature differences, the upper plate is connected to the lower container in such a manner that the upper plate can expand freely in the longitudinal direction. The lower plate has a stop member in its center region between the journals which member interacts with an adjustable stop of the frame. By stressed in order to make the beam insensitive to stresses resulting from temperature differences.
