Abstract—The main concept of this paper is to design and develop an automatic webbing machine for Olympic grade trampoline manufacture. The Australian company adopts a manufacturing process that produces double threaded trampoline net which has much better quality than the competitors. During the original weaving process, the wrap and the weft are continuous, so that the adopt double thread weaving is maintained. This specific weaving function leads to the popular weaving machine which are applied widely in textile industry cannot be introduced. Two manual machines were designed to manufacture trampoline nets but they limited the capacity of production. This paper focuses on the evaluation of the performance in manufacturing of the trampoline nets with pneumatic device controller which is based on the evidence and related material investigations. After designed in a CAD model, a proportionally scaled down prototype was manufactured using 3D printing technology. Preliminary test and evaluation were successful offering practical data and new improvement ideas for actual application and commercialization.
