The invention relates to a super-draft spinning method and a device adopting the same. Twisted fiber ribbons sequentially pass through a rear draft region, a middle draft region and a front draft region; double-rubber-ring draft is respectively adopted in the rear draft region and the front draft region, simultaneously, aggregation is carried out in the middle draft region and a draft multiple ofthe middle draft region is controlled within a range of 0.95 to 1.15 (not equal to 1) to implement super draft; and the device adopting the method comprises four pairs of rollers and leather rollers,which are arranged at intervals and up and down along an operation direction of the twisted fiber ribbons, a rear upper rubber ring, a rear lower rubber ring, a front upper rubber ring and a front lower rubber ring, wherein the four pairs of rollers and leather rollers are sequentially a rear leather roller and a rear roller, a first middle leather roller and a first middle roller, a second middleleather roller and a second middle roller, and a front leather roller and a front roller. The device is simple to operate. The method disclosed by the invention implements super draft of yarns in thepremise of ensuring yarn quality, and has very high popularization value.
