Abstract
The modulus of elasticity of a string portion or a string of uniform diameter for stringing a racket for ball games, in particular a tennis racket, differs in a section-wise manner. This may be by a stepwise change of the said modulus of elasticity along the length of the string or a stepless variation of the said modulus of elasticity along the length of the string.
Claims9
A string for stringing a racket for ball games comprising a string of uniform diameter having a length and width, wherein the modulus of elasticity of the string is different in a portion-wise manner along the length of the string, including at least one of said strings disposed in a tennis racket wherein said tennis racket includes longitudinal and transverse strings, and wherein at least one of the longitudinal strings has a different modulus of elasticity than at least one of the transverse strings.
