friedrich koenig develops a rotary press

moved back and forth under the platen while inking His partner Andreas Bauer and widow Fanny Koenig continued his life’s work. Announcing our NEW encyclopedia for Kids! After consideration he chose an abandoned monastery in Würzburg for the premises of the factory.

Johann Friedrich Gottlob Koenig, a German inventor, was born Apr. The to-and-fro movement of the bed that was retained in these early cylinder presses constituted an element of discontinuity; to make the cycle completely continuous, not only would the platen have to be cylindrical but the typeform also. The very first special presses for printing luxury color products followed at the beginning of the 1890s. engineer determined to apply steam power, already 1855 Würzburg Fanny Koenig and Andreas Bauer establish a sickness benefit fund which is still going strong. This new style of printing press could print up to 1,100 sheets per hour[1], printing on both sides of the paper at the same time. This year mechanical newspaper printing celebrates its 200th birthday.

The paper still had to be fed in by hand, though this part of the operation was mechanized by American-born British inventor William Church in 1824.

The dual portrait of Koenig and Bauer that we open with (first image) also seems to emanate from a KBA collection, although documentation is lacking. In 1814 the first stop-cylinder press of this kind to be driven by a steam engine was put into service at the Times of London. cylinders applied ink to the type. The Koenig-Bauer press had twin steam-driven rotary cylinders that were self-inked, and could print two sheets simultaneously, about 800 of them per hour. The firm was called Koenig & Bauer.

Printing and distributing thus became faster, more up-to-date and cost-effective. Given an equal amount of energy, the pressure exerted by a platen had to be spread over the whole of the surface to be printed, whereas the pressure exerted by a cylinder could be concentrated on the strip of surface actually in contact with the cylinder at any one instant. The press is said to have worked at the rate of 400 impressions per hour, a modest improvement on the hand press; he continued to make improve-ments until he finally realized that it could advance no further technically. Automatic folding devices, the first of which were designed by Bullock and Hoe, were incorporated into rotaries after 1870. The Linotype Machine was invented 1949. Other manufacturers in Germany, England, Austria and the United States sprung up and drove technical advances in press engineering with their ideas. In 1803, in Germany, Friedrich Koenig envisaged a press in which the raising and lowering of the platen, the to-and-fro movement of the bed, and the inking of the form by a series of rollers were controlled by a system of gear wheels.
