Izumi International Inc. (Greenville, S.C.) has developed the ST-CN creel system, featuring the same tension characteristics as the previous ST-5N-type spindle (stable tension regardless of package diameter), but designed to enable tension adjustment at a central location, as a convenience feature for applications that require frequent adjustment. Unlike conventional creels, on which tension increases as the package gets smaller, both the ST-CN and ST-5N maintain stable tension from beginning to end of package payout.
