Description

Process for the production of the parts of printing machines that do not undergo any change in shape due to the release of internal stresses, soHen parts of printing-machine-ii, wiL, 7. n, the Fumu. ments, and various cylinders are made of metal cast, which maintains internal tension due to the high and fc-Agünder cooling.

Since the parts are cast in polished molds, any processing is superfluous. In this way it is possible to use printing machines fully and with higher accuracy significantly lower costs than before.
