Synthetic cord for tennis racket

Abstract

Synthetic cord, specifically for tennis racket. According to the invention, the cord consists of a core, which consists of at least one small polyester monofilament ( 1 ), surrounded by small monofilaments ( 2 ), where a polyester elastomer layer ( 3 ) is enclosed between the various component layers. Applications: tennis cords, for easy cording, featuring a long life span, and a sharp reaction to the impact of a ball.

1 . Synthetic cord for tennis racket or other game racket, consisting of polyester, and distinguished by the fact that it consists of monofilament polyester threads of low diameter structured by cabling.  
   
   
       2 . Synthetic cord according to  claim 1 , distinguished by the fact that threads are cabled according to a metallic cabling scheme.  
   
   
       3 . Synthetic cord according to  claim 1 , distinguished by the fact that the cohesion of the polyester threads which comprise the cord, is ensured by a polyester thermoplastic elastomer ( 3 ).  
   
   
       4 . Synthetic cord according to one of the preceding claims, distinguished by the fact that the diameter of the monofilaments is between 10 and 45 hundredths of a millimeter.  
   
   
       5 . Synthetic cord according to one of the previous claims, distinguished by the fact that a structuring coating ( 4 ) surrounds monofilaments ( 2 ).  
   
   
       6 . Manufacturing device for a cord according to one of the preceding claims, consisting of a rotating platform, distinguished by the fact that the monofilaments pass through a coating tank by a polyester thermoplastic elastomer, then in an oven.
