Abstract
A register cam and a printing press incorporating the register cam are disclosed. The register cam permits the selection of alternative configurations that permit the alteration of parameters of the registration without the removal of the register cam from the printing press. The register cam can have one or more arms movably connected to and extending from the body. The one or more arms include at least two faces with each face having a distinct profile such that when an arm is in a first orientation a first face is presented to contact a gripper arm of the printing press and in a second orientation a second face is presented to contact the gripper arm of the printing press.
