Abstract
Musical instrument string or sports racket string, comprising a core which comprises or is composed of a bundle of thermoplastic fibers, wherein at least some thermoplastic fibers of the bundle are at least partially, such as for example in a punctiform or linear manner, connected to one another in a materially integral manner, in particular by fusing on the boundary surfaces, and method for producing said string.
Claims22
A string for a musical instrument or sports racket, comprising a string core, said string core further comprising a bundle of thermoplastic fibers with at least some said thermoplastic fibers of said bundle are partially-connected to one another in a materially integral manner by fusing the boundary surfaces of adjacent said thermoplastic fibers in a punctiform or linear manner wherein the elongation of said thermoplastic fibers at room temperature and at maximum tensile loading is less than 20%, and the elongation at break of said thermoplastic fibers is less than 25%.
A method for producing a string for a musical instrument or sports racket, comprising:
- orienting thermoplastic fibers into a bundle such that the elongation of the thermoplastic fibers at room temperature and at maximum tensile loading is less than 20%, and the elongation at break of the thermoplastic fibers is less than 25%;
- creating a string core by arranging the bundle of thermoplastic fibers;
- at least partially connecting some of thermoplastic fibers to one another by fusing the boundary surfaces of adjacent thermoplastic fibers in a punctiform or linear manner by heating the bundle of thermoplastic fibers continuously or in a batch-wise manner with a magnetic induction installation.
