ABSTRACT:
A belt-like screen carrying a row of printing patterns is held between two roller screen holders. The printing patterns are advanced one by one to a printing position by the rotation of the roller screen holders. This allows the printing patterns to be changed from one to another. Frames are provided for locking and unlocking the printing patterns at the printing position. The completion of a run of printed circuit boards can be monitored to automatically change the printing patterns.
