The classical of printing machine
Issue Time:2010-09-07

  Printing machine is the most common machine in the factory.  Printing machine generally installed version of the modern printing press, inking, stamping, feeding (including folding) and other agencies.

  A printing machine printing press, in its classical form, is a standing mechanism, ranging from 5 to 7 feet long, 3 feet wide, and 7 feet tall. Type arranged into pages is placed in a frame to make a forme, which itself is placed onto a flat stone or 'bed'. The type is inked, and the paper is held between a frisket and tympan (two frames covered with paper or parchment). These are folded down, so that the paper lies on the surface of the inked type. The bed is rolled under the platen, using a windlass mechanism, and the impression is made with a screw that transmits pressure through the platen. Then the screw is reversed, the windlass turned again to move the bed back to its original position, the tympan and frisket raised and opened, and the printed sheet removed. Such presses were always worked by hand. After around 1800, iron presses were developed, some of which could be operated by steam power.
