Abstract (en)
[origin: WO8602850A1] The method relates to the production of a string (24) for a racket, particularly a tennis racket. The string is a known string, for exemple a gut string or a synthetic string. The conditioning of the string on a support (1), particularly a bobbin, is effected under a traction tension and the length of the string is kept constant. Thus, the elongation of the string under the traction tension effect when winding the string on the support (1) is conveniently between 5 and and 15%. The stringing of the racket with the thus conditioned string (24) should be carried out in an interval of 60 minutes, but preferably 30 minutes, from the removal time of the string from its support (1). The relaxation of the string, i.e. the decrease of tension after the stringing of the racket, is considerably smaller with a string conditioned according to the invention than with a same string which has not been conditioned. Such relaxation reduction is particularly important with a polypropylene string.
