Title: Improvements in or relating to pneumatic tyres
Inventor: SMITH REGINALD SARGENT JAMES
IPC: B29D30/20
Filed: 1955-08-13
Abstract: 830,138. Pneumatic tyres. DUNLOP RUBBER CO. Ltd. July 23, 1956 [Aug. 13, 1955], No. 23363/55. Class 144 (2). A pneumatic tyre is made by first building a flat band of at least two cross-laid parallel cord plies each ply having a cord angle of from 40 to 70 degrees to the circumferential, forming the band to an embryo carcase approximately the final cross-sectional shape and dimensions of the tyre, and then applying to the shaped embryo carcase at least two additional parallelcord plies which are cross laid and each have a cord angle, before application, of from 10 to 30 degrees to the longitudinal edges of the ply the initial angular disposition of the cords in all the plies being such that the numerical values of the cord angles of the embryo carcase plies and the additional plies are respectively different in the crown region but substantially the same in the lower sidewall regions. The tyre is completed by application of the tread and sidewall rubber, with or without a conventional breaker or layer of harder rubber in the tread region, and final moulding. The shaping of the initial flat band plies reduces the cord angle in the tread region of the carcase from an original 70 degrees to about 50 degrees, the cord angle being substantially unaltered at 70 degrees in the lower sidewall regions. Likewise, the application of the additional plies to the shaped band effects an increase in the cord angle in the lower sidewall regions from an original 20 degrees, which is maintained in the tread region, to about 70 degrees. The changes in cord angle in the various plies are gradual and result in carcase having a laterally stiff tread region and flexible sidewalls. The cords of the various plies may be of steel, cotton, rayon, nylon, &c.
