Rubber Machinery: An Encyclopedia of Machines Used in Rubber Manufacture (Classic Reprint)

In crude rubber washing, mixing and calendering the problems were once thought to be comparatively simple and their solution about the same the world over. Today, however, scores of new and more efiicient machines handle new gums and intricate compounds, and the simplicity disappears. Even in the preparation of the crude material for market, machinery is to a marked degree supplanting hand labor. Rubber manufacture, be it noted, divides itself into some thirteen well defined classes. In these lines there are certain basic processes that all use washing and mixing, for example. It is true, also, that most of them make cements, for their own use at least; that a great number use tubing machines; that spreaders are used by others than proofers, and so on. The object of this volume is to record the machines that are of general application either to all or to a number of the lines into which the trade is divided. To this end voluminous matter has been collected from machinery makers the world over; from rubber factories, from patent specifications A merican, English, German and French. The actual value of such a collection to the rubber manufacturer, whatever his line, should be great, but the suggestive value will be even greater. To the manufacturers of rubber machinery in the United States, England, Germany, France and Belgium., the author takes the opportunity to express his thanks. Their generous promptitude in furnishing photographs, blue prints and details of special machines has made the task of arrangement and description much easier and the book far more complete than it could otherwise have been. The files of the India Rubber Journal, and Gummi-Z eitung and Le Caoutchouc etla Gutta Percha have also been of definite assistance in the collection of material, and my debt to these excellent journals is gratefully acknowledged.
