ABSTRACT:
A system for adjusting a finishing head relative to an impression cylinder in a printing, duplicating and like machine wherein copy sheets are fed through a printing couple and then to a finishing couple which includes the impression cylinder. The finishing head includes a finishing wheel for penetrating a copy sheet on the impression cylinder, and the head is mounted on a bar which is rotatably mounted between side frame plates of the machine. A preliminary adjusting mechanism is provided between the head and the bar for preliminarily adjusting the position of the finishing wheel relative to the bar. The bar is removably mounted between the side frame plates so that the preliminary adjustment can be made away from the machine. A very fine adjusting system is provided on the machine, operatively associated with the bar and including a dial on the outside of one of the side frame plates to provide fine adjustment of the finishing wheel while the machine is operating. A lateral adjusting mechanism is mounted on one of the side frame plates and is operatively associated with the bar for adjustably moving the bar longitudinally and thereby adjusting the finishing wheel axially of the impression cylinder.
