摘要： A golf ball is molded in a mold comprising a pair of removably joined mold sections. The golf ball has a plurality of dimples, the dimples being arranged in a polyhedral arrangement. The golf ball is free of a great circle which does not intersect with the dimples. The dimples (D2) lying across the parting line (P) between the mold sections, except for the dimples (D1) whose center lies on the parting line, are shifted upward or downward from the parting line or reduced in diameter so that these dimples are located outside the parting line (P). The dimple surface coverage is at least 71%. A golf ball having high symmetry and excellent flight performance can be prepared using a simple mold.

摘要： A method of manufacturing a golf ball is disclosed. A cover is molded through use of either a thermoplastic resin having a group capable of reacting with an isocyanate group or a thermoplastic resin containing a compound having two or more groups capable of reacting with an isocyanate group. Subsequently, a polyisocyanate compound is caused to permeate into the surface layer of the cover to thereby cause the reaction between the polyisocyanate compound and the group(s) capable of reacting with the isocyanate group. As a result, a modified layer having excellent properties is formed at the surface of the cover formed from thermoplastic resin. In this case, a non-yellowing polyurethane resin is preferably used as the thermoplastic resin having a group capable of reacting with an isocyanate group, and 4,4-diphenylmethane diisocyanate (MDI) is preferably used as the polyisocyanate compound.

摘要： In a golf ball having a parting line formed at the junction between a pair of mold sections and a plurality of dimples some of which lie across the parting line, the average space volume Vp of the dimples lying across the parting line is greater than the average space volume Vp' of the remaining dimples lying outside the parting line and/or the average Dp/Dm of the dimples lying across the parting line is greater than the average Dp/Dm of the remaining dimples lying outside the parting line wherein Dp and Dm are the depth and diameter of dimples, respectively. The golf ball is improved in symmetry in that no substantial difference occurs in flight distance between seam hitting and pole hitting.

摘要： A golf ball is composed of at least a pair of adjacent concentric solid layers or three adjacent concentric solid layers. In the former case, the outer solid layer is composed of a matrix and non-metallic high-hardness grains having hardness higher than that of the matrix which has a Shore D range of 36-40. In the later case, the intermediate solid layer is composed of a matrix and high-hardness grains having hardness higher than that of the matrix. The high-hardness grains have a Shore D hardness in the range of 50-70 and penetrate the corresponding solid layer in normal directions. The golf ball can provide a player with different feels on impact depending on the direction of an external force applied thereto when the golf ball is hit.

摘要： An injection mold for golf balls includes a pair of separable mold segments (1a, 1b). The mold segments (1a, 1b) are mated at their peripheral surfaces (12) along a parting line so that their inner surfaces (2a) define a spherical cavity (2). A plurality of dimple-forming projections (11) are formed on the inner surfaces (2a). At least four tubular gates (7) are disposed in the peripheral surfaces (12) and in fluid communication with the cavity (2). The peripheral surfaces (12) are furrowed except for the areas where the gates are disposed. Dimple-forming pins (14) are received in furrows (13) so as to lie across the parting line (PL). A molten stock material is injected into the cavity (2) through the gates (7) to mold a golf ball having dimples lying across the parting line.
