Abstract
559,054. Moulding rubber-felt products. MILES, H. G. W. CHICHESTER-, and STREET, W. O. May 29, 1942, Nos. 7311 and 16864. [Class 87 (ii)] A resilient product comprises a, casing of rubber or rubber-impregnated sheet material hot-moulded on to a felt body and completely encasing the latter, the rubber being of non- uniform thickness thereby giving the product an external contour different from tha,t of the felt body and obviating machining of the felt to the shape of the finished product. Prior to insertion in the mould, pieces of solid rubber may be secured to the felt by rubber solution or other adhesive ; alternatively the felt and rubber unit may be built up in the mould, or the felt may be supported in the mould and rubber mix injected therein. The non-uniformity in thickness of the rubber may be obtained by applying an increased thickness at the appropriate place, e.g. where a rib is to be formed, the mould cavity being shaped to form the rib. The felt may previously be impregnated with rubber.
