Patent ID: 7115181

Claim:
A method of manufacturing a rubber coated fabric for a tire utilizing a woven fabric obtained by weaving a warp constituted by a tire cord and a weft, which comprises coating the tire woven fabric with rubber to form a fabric base substance, cutting the weft of the fabric base substance by a cutting device at a cut pitch C P of two to five times an arrangement pitch P of the warp, by conveying the fabric base substance within a gap defined by the cutting device, said cutting device comprising a pair of rollers on an upstream side in a passing direction of the fabric base substance and a pair of rollers on a downstream side in the passing direction, wherein a phase of a pitch in an axial direction of the peripheral protrusions of the pair of rollers on the upstream side is displaced from a phase of a pitch in the axial direction of the peripheral protrusions of the pair of rollers on the downstream side by one half pitch each of said pair of rollers including a first roller in which peripheral protrusions and peripheral grooves are alternatively and continuously provided in an axial direction and a second roller in which opposing peripheral protrusions and peripheral grooves are alternately formed in the axial direction, said protrusions and grooves of the first and second rollers being offset so that the protrusions of the first roller engage the grooves of the second roller, and vice versa, whereby groove widths W 1 and W 2 of the peripheral grooves are set between 2.0 and 5.0 mm, protruding widths T 1 and T 2 of the peripheral protrusions are set to 0.25 to 0.5 times the groove widths W 1 and W 2 , and insertion depths h 1 and h 2 of the protrusions to the peripheral grooves are set between 2.0 and 4.0 mm.
