Screen printing device, comprising an endless printing belt on which a web of material can be fixed temporarily, a printing belt drive device, and a number of rotary stencils driven by stencil drive devices, the printing belt drive device being coupled to the stencil drive devices at a predetermined angle presetting thereof for a synchronous movement thereof. The device also has a signal generation device which can produce a signal forming a measure for a displacement of the printing belt. One or more markings are provided on or in the printing belt and can be detected by detectors securely fixed at predetermined intervals. A comparison device compares the signal coming from the signal generation device, during a displacement of a marking on the printing belt from one detector to a next detector, with a predetermined reference signal, following which a correction device adjusts the angle presetting of one or more stencils on the basis of the comparison result of the comparison device.

Screen printing device with continuous registering of rotating stencils

A screen printing machine comprises a frame in which one or more stencils are supported for printing a web of material fixed on a supporting belt. The stencils are each directly connected by means of a rigid coupling to the rotor of a corresponding rotary drive device. An elongated squeegee, supported near the ends of the stencil, is provided in the interior of each stencil. The drive device is provided with a central through hole running in the axial direction, for allowing through at least the end of the squeegee with radial play.
