Abstract
735,692. Strengthening edges of sheet material. MANSELL, E. A., and FRANKLIN & SONS, Ltd., J. G. June 30, 1952 [April 4, 1951], No. 7789/51. Class 42 (1). [Also in Group VI] An edge is formed on sheet material, e.g. rubber, by disposing the sheet 4 as a sleeve on a former 5, on which it may have been coated by dipping, and placing a reinforced core round the sleeve near its edge and then rolling it along the sleeve so that the material wraps itself round it, when it may be prevented from unwinding by adhesive. The core comprises a tube of closely coiled wire 2 which itself encloses a peripherally inextensible inner member 3, e.g. a flat spiral of steel strip. The Provisional Specification mentions application to the beaded edges of pneumatic tyre covers.
