The Manufacture of Dry Core Paper Cable

Abstract

With the great development in telephone and telegraphic engineering, the use of dry core paper cable has become very extensive and its knowledge is becoming quite imperative to all engineers. The author describes the various kinds of dry core paper cables and the manufacturing processes connected therewith with a table of general dimensions and shapes of the materials used in the manufactuce of such a cable. Mention is also made of the various types of machinery used in the manufacture of dry core cable and the function each is supposed to perform. For the benefit of those interested, dielectric and other prop rties of the materials used in the cable with two or three examples of cable design.
