Abstract: The rapier loom needs empty running-in before leaving the factory. Since there is no weft weaving, it is impossible to verify whether the function of the weft detection system is in good condition.In order to fill this gap, a test platform has designed to verify the function of the entire weft detection system. This paper elaborates on the design process of mechanical principles, electrical principles and test procedures.

Key words: rapier loom; running-in; weft detection; test platform
