  • Patent number: 5238620
    Abstract: A grip sleeve is manufactured by sleeving a tubular nylon fabric lining on a cylindrical mandrel of appropriate length. The mandrel is then provided on a lower mold half which is formed as an elongated shell that is semi-circular in cross-section. The lower mold half has an inner surface which is formed with a pair of spaced and curved radial projections that support the mandrel. An upper mold half is provided on top of the lower mold half and matches with the lower mold half. The upper and lower mold halves cooperate with the mandrel to define an enclosed annular receiving space. One of the upper and lower mold halves is formed with an inlet to access the receiving space. A molding composition of elastomeric foam is introduced into the receiving space via the inlet so as to fill the receiving space. The molding composition solidifies to form an elastic and perspiration holding layer on the fabric lining, thereby producing the grip sleeve.
