Patent Model for a Rotary Web Perfecting Press

Wright, John K. · ca 1869

This patent model demonstrates an invention for a rotary web perfecting press which was granted patent number 91191. The two pairs of printing cylinders had surfaces that were half type bed and half impression blanket, the type on one backing onto the blanket on its mate. As the web passed through the first pair, alternating parts of the paper were printed on each side. Then the web passed through the other pair, and the impression was completed. After printing, the web was cut into sheets.
