| | Stone Industrial (a division of Precision Products Group)Stone Industrial began in 1888, in Washington, D.C., when Marvin Stone patented the spiral-winding process to manufacture the first paper drinking straws. The company began as a manufacturer of paper cigarette holders when Mr. Stone got the idea for making drinking straws from paper as a substitute of the rye grass straws used at the time. The first straw was made by winding strips of paper around a pencil and gluing it together. The new idea was test-marketed at a local drinking establishment where it was enthusiastically received. He then improved on the design by experimenting with paraffin-coated manila paper so the straws would not become soggy. The product was patented and by 1890 the factory was producing more straws than cigarette holders. In 1906, the first machine was invented by the Stone Straw Corporation to machine-wind straws thereby eliminating the hand-winding process. This same machine was later adapted to manufacture other kinds of spiral-wound paper products that, for example, replaced wooden bobbins commonly used in knitting mills.In 1928 electrical engineers began to use spiral-wound tubes as cores, spacers, and insulators used in the first mass produced radios. Since that time the process of spiral-wound tubing has found numerous uses in electric motors, electrical apparatus, electronic devices, electronic components, aerospace, textiles, automotive, fuses, batteries, transformers, pyrotechnics, medical packaging, product protection, and consumer/commercial packaging applications.Today, Stone Industrial is an ISO 9001:2008 Registered company recognized as a world-class supplier of innovative, close tolerance, precision engineered, custom tubing products. They have two sister divisions: Paramount Tube in Fort Wayne, IN and PPG China in Changzhou, China.
