To provide a simple and highly general method for producing a wide angle canvas, by which a plurality of crossed axes angles between warps and wefts can be realized substantially without damaging yarns constituting the canvas.
This method for producing the wide angle canvas comprises preliminarily applying an adhering treatment process to a canvas 12 comprising warps 12a and wefts 12b, winding the canvas 12 on the circumferential surface of an inclined roll 31 disposed to be inclined at an inclination angle α of a rotation axis to the width direction of the canvas 12, and then moving the canvas 12 in a direction parallel to the longitudinal direction in the state to incline the wefts 12b (wide angle treatment). The inclination angle α can be changed in a prescribed range. Then, the canvas 12 is dried in a drying process.
