Patent ID: 7809464

Claim:
A registration system comprising: a sheet fed machine, the machine including a feed mechanism, a feed section, and one or more processing sections, the one or more processing sections each including a pair of cylinders to modify and advance a sheet; a computer; an operator-visible information display operable to display data from the computer; at least one user actuated mechanism for adjusting an angular displacement of a cylinder within each pair of cylinders; a feed mechanism sensor associated with the feed mechanism, the feed mechanism operable to advance one of a plurality of sheets into the sheet fed machine, the feed mechanism sensor generating an electronic pulse by sensing a target associated with the feed mechanism; a section sensor placed in the one or more processing sections; a section target mounted to a cylinder in the pair of cylinders included in the one or more processing sections, the section sensor operable to detect the section target and to send an electronic pulse to the computer when the target is detected; and the computer 1) calculating a speed of each cylinder to which a section target is mounted and 2) tracking the elapsed time from receipt of the feed mechanism pulse to each processing section pulse, the computer then calculating the relative position of each cylinder with a target with respect to the electronic pulse generated by the feed mechanism sensor and displaying the relative position of each cylinder via the information display.
