Method of making golf club grip with anti-slip and control arrangement

Abstract

A method of making golf club grip includes the steps of overlapping a textile fabric on a first raw rubber layer and painting a rubber latex on the textile fabric to attach the textile fabric on the first raw rubber layer to form a thin reinforced rubber layer laminated with the textile fabric; preparing a second raw rubber layer which is shaped and sized to form two control members; shaping the first raw rubber layer to form two anti-slip members; aligning the anti-slip members with the pair of control members in an end to end manner in two halves of heat mold respectively; and vulcanizing the anti-slip members and the control members in the heat mold to form a golf club grip including a tubular anti-slip arrangement and a control arrangement coaxially extended from a lower end of the anti-slip arrangement.
