Cylinder Presses
The first cylinder press was invented and developed by Friedrich König and was installed in The London Times in 1814. Flatbed-form presses — which describe the cylinder and its opposed-running form or bed — offered the possibility for larger printing forms using less energy and better impression quality.
We distinguish four varieties of cylinder presses:
Stop-cylinder press.
After each impression, the cylinder comes completely to rest while the flat bed with the printing form is underway returning to its starting position under a cut-away portion of the cylinder.
Swing-cylinder machine.
The cylinder always follows the forward and reverse motion of the bed of the press with the form.
Two-revolution press.
After impression the cylinder continues to revolve for one non-printing revolution, while the form returns to its original starting point.
Single-revolution press.
The over-sized cylinder has about double the dimension of the form. A half-revolution makes the impression, then the form returns to its starting point during the second half-revolution.
