摘要： Thread--wound golf balls are prepared by winding a rubber thread around a frozen core to form a core ball, immediately thereafter microwave heating the core ball to thaw the core, and forming a cover over the core ball. Microwave heating causes the frozen core to be briefly thawed without heating the thread rubber layer and without moisture condensation on the core ball surface, reducing the time taken for the core thawing step and eliminating the need for a drying step.

摘要： Golf balls are manufactured by supplying a golf ball - forming material into a mold defining a cavity of a predetermined surface pattern, thereby forming a golf ball having a surface pattern transferred from the mold cavity surface pattern. The mold is prepared by way of electroforming. First using an elastic non-metal profiling material, a male duplicate master is fabricated from a female standard mold having at least one accessory for assisting molding or post machining such as a parting surface and reference surface. An electroformed mold is fabricated from the male duplicate master. This electroformed mold is ready for use as the ball manufacturing mold.

摘要： A rotary roll extruder which performs shaping of material to be extruded such as raw rubber, or the like by ejecting the material to be extruded through a mouth piece by means of an extruding roll. This extruder comprises mouth piece moving means for moving a mouth piece in a radial direction of an extruding roll to make the mouth piece approach, or separate from, the circumferential surface of the extruding roll, mouth piece positioning means for positioning the mouth piece when the mouth piece is held apart from the extruding roll, and mouth piece stocking means for preliminarily stocking various kinds of mouth pieces. Shaping of the material to be extruded is effected when the mouth piece has been brought close to the circumferential surface of the extruding roll by the mouth piece moving means and it has been positioned by the mouth piece positioning means. However, for the exchange of the mouth piece, the mouth piece is separated from the extruding roll by the mouth piece moving means, and is exchanged with one of the mouth pieces stocked in the mouth piece stocking means. Thereafter, the new mouth piece is brought close to the circumferential surface of the extruding roll by the mouth piece moving means, and is positioned by the mouth piece positioning means. The mouth piece exchange work is executed automatically without the aid of any human labor.
