Definitions
- the invention relates to a string for stringing rackets for tennis and related games, such as badminton and squash.
- a metal covering is far less sensitive to the effects of the weather, besides it has a higher tensile strength and is therefore more durable. It retains constant flexibility and resilience even under heavy use. A sufficiently high elasticity of the covering can also be achieved with the available wire materials. Finally, the metal covering rather cheaper to manufacture.
- the use of stranded, stranded or twisted metal wire gives the covering a relatively rough surface, which makes it possible to hit the ball with a high twist effect.
- the surface structure can be changed by using different string constructions. There is therefore also the possibility of making the covering less easy to grip, for example in order to prevent the balls from wearing out too quickly. In this sense, it may also be advantageous to provide the metal wire with a plastic sheath.
- the string preferably has a core made of a material which is several times more elastic than the wire material, in order to increase the extensibility of the string.
- Plastic is the primary material for the soul, e.g. Polyamide, in question.
- the string has a plastic core, the diameter of which is greater than the thickness of the metal wire and which is tightly wrapped with several round, parallel metal wires in the form of a multi-start coil spring.
- the ratio of diameters and the number of metal wires By choosing the ratio of diameters and the number of metal wires, the elasticity of the string can be changed within wide limits and adapted to the respective requirement. Similar elasticity values as for a conventional gut string can be achieved, for example, with a metal string of this type, the plastic core of which has a diameter of 0.7 mm and is wound with six steel wires, the diameter of which is 0.28 mm. With a larger number of metal wires running in parallel, there is a greater increase in the wire windings and thus a lower elasticity.
