发明名称 Tennis racquet stringing system - uses two groups of strings extending in same direction crossing each other and placed alternately in front and behind other group
摘要 <p>The tennis racquet (10) has at least two gps. of strings extending at a distance from each other in the same direction. The strings from one gp. cross those of the other gp. and run at the crossover points alternately in front of and behind the strings of the other gp. so that the stringing of the striking surface forms a wide mesh. The strings of one gp. extending in one direction are first inserted and then placed on one side of them the strings of the other gp. leaving out an intermediate string are inserted. Subsequently the intermediate strings of the first gp. are drawn in on that side facing away from the already inserted strings of that gp. and onto the transverse extending strings of the other gp. also placed on one side. Finally the still missing intermediate strings of the last gp. of strings are inserted and are led alternately in front of and behind the strings extending transverse to the first gp. of strings.</p>
