ADJUSTABLE FORM ROLL APPARATUS

An apparatus for adjustably positioning a form roll having a form roll axis against at least two different sized plate cylinders in a variable cutoff printing unit is provided. The apparatus includes a plate cylinder support for interchangeably supporting the at least two different sized plate cylinders, the plate cylinder support including a plate cylinder axis at least two different sized plate cylinder cams. The at least two different sized plate cylinder cams are interchangeably removably connectable to the plate cylinder support and include a smaller plate cylinder cam and a larger plate cylinder cam that are removably connectable to the plate cylinder support as alternatives of each other. The apparatus also includes a form roll hanger for supporting the form roll that is configured for contacting the smaller plate cylinder cam if the smaller plate cylinder cam is coupled to the plate cylinder support to set a smaller distance between the plate cylinder axis and the form roll axis. The form roll hanger is also configured for contacting the larger plate cylinder cam if the larger plate cylinder cam is coupled to the plate cylinder support to set a larger distance between the plate cylinder axis and the form roll axis. A method of adjustably positioning a form roll and a variable cutoff printing press are also provided.
