Why do most professional stringing machines look the same?
The professional stringing machines with manual crank spring tensioners are “clones” of the Ektelon H model stringing machine. The earliest clone of the Ektelon H model is EAGNAS EAG-500 model. In 1992 Czechoslovakia began to manufacture stringing machines. Czech stringing machines use a similar design to those manufactured in Taiwan. • How many different type of mounting systems are available on current model stringing machines? There are only two types of mounting systems: the hold-down (press-down) mounting system and the suspension (air-support) mounting system. The suspension mounting system uses the 4 V-shaped side-support arms to support the racquet. See Figure 3-1. The head and throat mounting posts are only hold the racquet in place. For the hold-down mounting system, the supports are the head and throat mounting posts. See Figure 3-2. The side-supports are only to hold the racquet in place to prevent from distortion. The hold-down mounting systems are more secured and stable
