Abstract
Abstract In tennis rackets and the like a faster and more efficient method of stringing racket frames wherein the strings are inserted and tensioned within the frame without interweaving the longitudinal and latitudinal strings. The net thus formed is than consolidated into a unified structure by bonding the longitudinal strings to the latitudinal strings at each point that the longitudinal strings cross the latitudinal strings.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
A method of stringing a game racket, having at least a frame, shaft, handle and strings, which method includes the steps of: inserting and tensioning the longitudinal strings, consisting of a plurality of spaced apart parallel runs of said longitudinal strings, within the frame, so that the longitudinal strings lie in the same plane; inserting and tensioning the latitudinal strings, including a plurality of spaced apart parallel runs of said latitudinal strings, within the frame on only one side of the plane formed by the longitudinal strings, without interweaving the longitudinal and latitudinal strings; and bonding the longitudinal and the latitudinal strings together at their cross over points, thereby consolidating the longitudinal and latitudinal strings into a coacting net of strings.
Claim 2
Independent Claim
121 words
A method of stringing a game racket, having at least a frame, shaft, handle and strings, which method includes the steps of: inserting and tensioning the longitudinal strings, consisting of a plurality of spaced apart parallel runs of said longitudinal strings, within the frame, so that the longitudinal strings lie in the same plane; inserting and tensioning the latitudinal strings, including a plurality of spaced apart parallel runs of said latitudinal strings, within the frame on only one side of the plane formed by the longitudinal strings, without interweaving the longitudinal and latitudinal strings; and bonding the longitudinal and the latitudinal strings together at their cross over points, thereby consolidating the longitudinal and latitudinal strings into a coacting net of strings.
Claim 3
Dependent Claim
83 words
In the method of claim 1 including, inserting and tensioning additional latitudinal strings, including a plurality of spaced apart parallel runs of said additional latitudinal strings, within the frame on the side opposite said one side of the plane formed by the longitudinal strings, without interweaving the longitudinal and said additional latitudinal strings; and bonding the longitudinal and said additional latitudinal strings together at their cross over points, thereby consolidating the longitudinal and said additional latitudinal strings into a coacting net of strings.
