Electricity in newspaper printing

After giving a brief history of the part electricity has played in the production of newspapers and an outline of the processes involved therein, the paper deals with the present electricity-supply requirements for typical newspaper offices. A description of a modern newspaper-printing press and its special drive requirements is followed by a comprehensive survey of the electrical drive and control equipment of a press, with typical examples. The paper concludes with some notes on the control of the paper rolls and web, on the electric heating of stereo metal and on wiring. To make it possible to deal more fully with the power-engineering aspect of the subject, no mention is made of the part that electricity plays in the transmission of news and pictures.
