  • Patent number: 4466166
    Abstract: A Mandrel and method of using the same to form an elongate rigid guide that has a first elongate portion over which an elastomeric tube may be slid. A second elongate end portion of the guide when axially aligned with the handle of a tennis or racquet ball racquet may be caused to removably engage the same. Anti friction means are provided on the guide to facilitate the longitudinal movement of the elastomeric tube thereon. The handle of the racquet has a transverse cross sectional area substantially greater than that of the interior of the elastomeric tube. After the guide is in engagement with the handle, the elastomeric tube is moved towards the latter. Prior to the elastomeric tube moving onto the handle it is radially expanded to conform to the exterior configuration of the handle. After the tube is mounted on the handle the guide is separated from the handle, with the tube frictionally engaging the tube to define a grip thereon due to the tube being circumferentially stressed.
