FA563的限戒指

FA563 Ring Frame is designed on the base of FA561, which has the advantages of FA561 and the machine head is oil-bathed. 1. The spindle positioning technology is used to reduce yarn breakage and misdraft. Manually knocking spindles is removed to save labour and improve efficiency through the method of fixing spindle and adjusting ring to make the spindle and ring precisely concentric. 2. In conditions that not reduce the pressure to leather roller and roller in unit area (pressure intensity not changed), reduce the distance between top and bottom roller to reduce 1/3 pressure of the weighting arm. In addition, mid-short apron double S drafting is used to improve the stability of apron so as to improve the control to floating fiber. Therefore achieve the purpose of reducing consumption and saving energy. This device has been declared national invention and design patent. The drafting structure of changing long-short apron drafting into mid-short apron drafting is exclusive internationally which make high-quality, efficient and energy-saving spinning comes true.
