Richard M. Hoe patented the first printing press with a rotary movement in 1847. Although this machine brought great speed improvement in comparison with the flatbed press, it still didn't use continuous rolls of paper. This feature was initiated by William Bullock, and Richard M. Hoe added it to his web perfecting press, which was built in 1871 and used for the first time by the New York Tribune. It could print on both sides of the sheet and produce 18 000 papers in an hour.
