Rotary presses were used for high-speed work. In the oscillating press, the forme slid under a drum around which each sheet of paper got wrapped for the impression, sliding back under the inking rollers while the paper was removed and a new sheet inserted. In a newspaper press, a papier-mâché mixture called a flong used to make a mould of the entire form of type, then dried and bent, and a curved metal stereotype plate cast against it. The plates were clipped to a rotating drum and could print against a continuous reel of paper at the enormously high speeds required for overnight newspaper production.
