Abstract:Aiming at the problems of complex structure and high manufacturing cost of finger tensioner used in evenness tester，a tension wheel device is designed to realize different clamping tension through different yarn drawing forms.The structure design of the tension wheel device，six yarn winding modes and the calculation of the minimum initial tension and critical friction of the samples are described in detail.The CV values of the 9.72 tex，14.58 tex and 18.22 tex roving samples in the finger tensioner and tension wheel device are tested and compared. The results show that the tension wheel device has the advantages of simple structure，easy processing，low cost and stable test performance，which can meet the different clamping tension requirements of the test specimen，and can completely replace the existing finger tensioner.
Key Words:evenness tester；finger tensioner；tension wheel device；winding mode；roving； evenness CV value
