  • Screen printing device with continuous registering of rotating stencils
    Patent number: 5255598
    Abstract: 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.
