A box blank forming apparatus includes at least one printing assembly (12, 14), a slotting assembly (18), and a feeding (24) and conveying (28) mechanism for feeding blanks (26) through the apparatus. The feeding (24) and conveying (28) mechanism brings the blanks (26) into contact with the printing cylinder (44) and the slotter blade (96) to complete printing and slotting operations on the blanks (26) in the formation of boxes. An interrupter (52) is provided in association with the printing assembly (12, 14) for removing the blanks (26) from contact with the printing cylinder (44), and similar structure can also be provided with the slotting assembly (18) for removing the blanks (26) from contact with the slotter blade (96). A controller (120) is provided for controlling operation of the interrupter (52) of the printing assembly (12, 14) and may be used to also actuate the interrupter structure (106) of the slotter wheel assembly (18). This allows the printing assembly (12, 14) and the slotter wheel assembly (18) to accomodate box blanks of variable length. |
