Abstract A device for the treatment, particularly for the printing, of flat-shaped material which is moved between two working elements exerting a pressure upon each other. One of the working elements, particularly the printing support of a printing form body, contains a magnet body consisting of a plurality of electromagnets whose magnet cores are arranged in one or more lines having preferably axes perpendicular to the flat shaped material to be treated. The magnet cores project into a stable support body directed to the flat-shaped material to be treated, covered, if the case may be, by a thin casing wherein the stable support body is provided with a recess or perforation passing through the line of magnet cores in whose zone the pole faces of the magnet cores end at a distance from the surface of the support body directed to the material to be treated.
A device for the printing of flat-shaped material comprising two working elements exerting a pressure upon one another between which said material is passed, one of said working elements forming a printing support containing a magnet body having a plurality of electromagnets having magnet cores, said magnet cores being arranged in series with their axes perpendicular to said flat-shaped material, a stable support body turned toward said flat-shaped material into which said magnet cores project, the other of said working elements forming a squeegee arranged in and engaging in a printing screen said printing screen contacting said material opposite said support body, said printing screen contacting said material opposite said support body, said stable support body having a recess extending over said series of magnet cores so that the pole faces of said magnet cores terminate at a distance from the surface of said support body turned toward said material to be printed, and said surface of the stable support body turned toward the material to be printed being provided with a thin sheet cover capable of being deflected into said recess of said stable support body.
