The development of the sectional paper-machine drive

To an increasing degree, large machines designed for quantity production are being subdivided into their elements, each section being driven by a separate motor as contrasted with former practise of driving these machines, as a whole, from a single unit. With the paper machine, this is called the sectional-electric drive. In this paper, the author has confined himself largely to the history and development of the several types of the sectional drive and the relative merits of each particular type. An attempt has been made to set forth clearly the advantages of the sectional drive and to show that its field of application should increase with a fuller understanding of its advantages as to increased production, improved product and lower operating cost.
