Abstract: An apparatus for intermittently driving an endless belt by two electric motors in an automatic screen printing machine, which comprises a pair of rollers, an endless belt supported on the rollers, a direct current electric motor for intermittently driving said rollers and a control mechanism for setting a repeat length of the endless belt while converting it to a pulse number, detecting the actual feed length of the endless belt as a pulse number and subtracting the detected pulse number from the set pulse number to stop the endless belt at the repeat length corresponding to the set pulse number.

Abstract: An automatic screen printing process comprising the steps of continuously driving an endless belt to apply and stick a material to be printed onto the endless belt along a predetermined length smaller than one travelling circle of the endless belt, then driving the endless belt intermittently to feed the material to be printed to a printing operation zone and a drying operation zone, while repeating the cycle of the printing operation during stoppage of the endless belt and the operation of travelling the endless belt along a repeat length during stoppage of the printing operation, thereby to print the entire surface of the material applied to the endless belt and dry the printed material, and repeating said printing step until a pattern of a predetermined number of colors is obtained is disclosed.
