ABSTRACT:
A control mechanism for an offset printing machine in which total printing operation is efficiently and easily carried out through a single control shaft with a knob.
The control mechanism is operative in a combination of an automatic mode and a manual mode to utilize advantages of both modes. The control shaft is rotatively constructed in such a way that its neutral position, its position for supply of ink and dampening solution to rollers, its position for transfer of ink and dampening solution to a master cylinder, its position for paper feeding and printing, its position for blanket cleaning, and its position for stopping the machine make one complete cyclic loop. The control shaft is manually rotated stepwise from its neutral position to its position for paper feeding and printing. After a pre-set number of sheets are printed, the control shaft is automatically rotated to its position for blanket cleaning and then to its position for stopping the machine.
