A NEW METHOD FOR MANUFACTURING OF ROPES USED IN NET OR ROPE CLIMBING GAME GROUPS

Abstract

Nowadays, climbing game tracks are available for children and for young people and adults. Some of these game tracks are climbing tracks designed as a net. Other ones are climbing groups comprising ropes and similar structures that are suitable for gripping by the hand. There are also game tracks that include both basic game tracks or have different designs while maintaining the fundamental characteristics. However, their common characteristic is that they allow people to try to grasp the rope or net tightly and play or do exercise with an experience close to the natural environment. For this reason, yarns (strings) made of materials such as nylon, polypropylene or polyester are either directly knitted or adhered with chemical adhesives on steel wires. However, during its use, the knitted or adhered yarns (strings) on the steel wire are opened, disorganized or worn. This causes the wires to corrode and / or wear under ambient conditions and thus shorten the life of the ropes. In this study, a solution has been developed to provide a rigid coating of these yarns on the wires. In our study, after the threads were wound on the wires, the steel wires were heated by an electromagnetic induction current and thus, the threads on the steel wires were softened with the effect of the heat. Then, during cooling, the threads harden and partially adhere to each other. Due to this heating process, the temperature was kept under control in order to prevent the properties of the steel wires from deteriorating. After the wires were produced, they were tested with tensile test, hardness and metallographic examination methods, and changes in their properties were controlled.
