  • Patent number: 5222998
    Abstract: A device can be provided in different embodiments for holding different tensions in different length string sections of a sports racquet stringing bed. In one embodiment, a strip of material is applied on the periphery of the head portion of the racquet and is compressed under the string portions extending between pairs of adjacent stringing holes. In another embodiment, the tension holding device is a plurality of cylindrical bands of compressible material which fit about the string portions and within the grommets of the racquet. In both embodiments, the material is compressed by the string portion to generate sufficient frictional force therebetween to prevent slippage of the string portion relative thereto and thereby hold the different length string sections under the predetermined amount of differential tension.
