Title: Improvements in rubber articles and method of making the same
IPC: B29D30/06
Filed: 1936-11-26
Abstract: 480,204. Preventing cracking of rubber articles. CONSOLIDATED RUBBER MANUFACTURERS, Ltd. (Havens, G. G.) Nov. 26, 1936, No. 32373. [Class 70] Rubber articles are rendered less susceptible to cracking by stretching at least part of the surface of the previously vulcanized article, applying heat to the stretched surface to render plastic a thin layer of rubber, allowing the plastic rubber to set over the underlying stretched rubber of the body, and releasing the stretched body whereby the thin re-set layer is placed under compression. The Figure shows the application of the invention to pneumatic tyre casings. To lessen the tendency of cracking at the base of the grooves defining the anti-skid configurations, the side walls of the tyre casing are clasped between plates 2, 3 whereby the grooves 6 in the tread are caused to flare outwardly and produce tension in the rubber at the bottom of the grooves. While so held steam, (preferably superheated steam at about 550‹ F.) is directed for about 20 seconds through nozzles 7 to the bottom of the grooves, the tyre is then cooled rapidly, preferably by a stream of cold water, and allowed to assume its normal form. The side walls of pneumatic tyre casings, footwear and belting may be similarly treated.
