ABSTRACT:
The invention relates to screen printing apparatus which comprises a printing station, means for feeding a web of material to be printed to the printing station and away therefrom, a squeegee mounted at the printing station for cooperation with a screen printing mesh, means for attaching a screen printing mesh tensioned on a frame so that part of the mesh is at the printing station, means for reciprocating such a screen printing mesh in a frame through the printing station, means for feeding ink to one side of the squeegee, a profiled support at the printing station for supporting the material to be printed, and means for advancing the screen mesh in a frame and the material to be printed at the same speed past the printing station while biasing the screen mesh by means of the squeegee towards the support. According to the invention the profiled support is movable in order to compensate for changes in the shape of the screen mesh during the printing stroke. Furthermore, improved quality is obtained by means of a clamping bar system for advancing the material to be printed past the printing station.
