Patent Model for Rotary Perfecting Presses

This patent model demonstrates an invention for a rotary perfecting press which was granted patent number 92050. The patent details improvements to sheet- or web-fed perfecting presses. Instead of being attached to the impression cylinder, the press blanket was an endless web that travelled with the paper and acted as its support. The press was patented in England in 1871 (Patent 1825 to W.E.Newton).
