Abstract:In order to solve the deterioration of spinning quality index，especially the significant change of CV_b value caused by fatigue decline of V-type upper-spin spring of pneumatic pressure cradle，the idea of technological breakthrough and reform practice of cradles are introduced，and the performance and spinning quality index of draft pneumatic pressure cardle and spring pressure cradle used in cotton ring spinning frame are analyzed and compared.It is pointed out that in order to ensure the control effect of the drawing center of phneumatic pressure cradle can reach the drawing center of spring pressure cradle，the phneumatic pressure cradle with L-type upper-pin pressure controller is applied，which is convenient for maintenance worker operation.No fatigue and deformation will occur after long-term use，and the yarn quality index is stable，CV_b value and strength CV value are reduced.
Key Words:phneumatic cradle；L-type pressure controller；top cradle；CV_b；strength CV
