Abstract
A method of producing a rubber thread for a golf ball includes (a) an extruding process of extruding a rubber composition in the shape of a sheet by using an extruder (2) to obtain a sheet material (6); (b) a rolling process of rolling the sheet material (6) to make it thin to obtain a thin sheet material (10); (c) a cross-linking process of cross-linking the thin sheet material (10) to obtain a cross-linked sheet material; and (d) a cutting process of cutting the cross-linked sheet material to obtain a rubber thread. The rolling process is performed successively to the extruding process. The thickness t1 of the sheet material (6) obtained in the extruding process is set to a range of 1 mm to 8 mm both inclusive. The thickness t2 of the thin sheet material (10) obtained in the rolling process is set to a range of 0.3 mm to 0.6 mm both inclusive.
