Abstract (en)
[origin: WO2009003723A1] The present invention relates to a string for a ball racquet, the string having at least two filaments which run parallel to each other, wherein the filaments are connected to each other only in some sections. Furthermore, the invention relates to a method for producing a string of this type. A first method has the steps of providing at least two string filaments, bringing together the string filaments to form a configuration running in parallel and connecting the string filaments in some sections. An alternative production method has the steps of providing a string and slitting the string in some sections in order to produce at least two string filaments which run parallel to each other and are connected to each other only in some sections.
