Filed: 1943-02-11
Abstract: 563,948. Making tyres. WINGFOOT CORPORATION. Feb. 11, 1943, No. 2297. Convention date, Aug. 8, 1942. [Class 144 (ii)] In a pneumatic tyre built up of a number of layers or plies of rubberised cord fabric, the angle between the cords and the great circle of the tyre is greatest at the innermost ply and progressively decreases in the outer plies at stepped intervals of one or more plies. Fig. I shows the construction in which the innermost ply 10 is at an angle of forty degrees to the centre while the outer plies decrease to an angle of thirtyseven and three-quarters degrees. The plies are assembled in bands each consisting of a number of plies each cut at substantially the same angle, but the angle of the cord in successive bands progressively decreases, the plies being cut from the fabric on the required skew which varies with each ply or group of plies. The same result of cord angle is achieved by cutting the plies at the same bias angle but cutting each successive band (in group by superimposed plies) shorter so that the extra stretch required to make it go round the circumference alters the cord angle, or the band may be of the same length but the increase in circmnference outwardly as the tyre is being built up requires an increase in stretch during application to give an approximately similar result.
