An on-line fiber drawing tension and diameter measurement device

A noncontact online drawing tension meter is described. This meter measures both the drawing tension and fiber diameter during the fiber drawing process. Experimental results show that this meter functions satisfactorily in all aspects of testing. The knowledge of online drawing tension not only helps in the manufacture of fibers with low surface tensile stress, but it also gives information about furnace temperature change and the viscosity of the glass at the neck-down region.<
