Applying particles and adhesive to racquet strings

Abstract

Method and apparatus for conditioning the surface of the strings of a racquet such as used in tennis and other racquet sports. The method comprises a first step of applying a first primer coat of adhesive to the strings in the central portion of the racquet by spraying it through a template. The first coat of adhesive is applied to both sides of the strings and after drying a second coat is applied thereto. A granular substance, such as white quartz fractured to the size of 1/50th of an inch having a general cubical-shape, is sprinkled over the second coat of adhesive while damp. After the abrasive settles in and dries, a final sealing layer of adhesive is sprayed over the quartz crystals and second coat. This process both coats and locks the strings together at the intersections to lengthen strike-life and also forms a rough frictional surface on the strings to provide better ball control and create a better spin on the ball when hit.
