1. A device for continuously winding strands of hollow fiber membranes, comprising
i) a first winding reel and a second winding reel, wherein both the first winding reel and the second winding reel are circular and have the same diameter, wherein the first winding reel and the second winding reel are aligned and spaced apart from each other;
ii) a fiber-guiding unit comprising three rollers, wherein the three rollers comprise a first roller, a second roller, and a third roller, wherein the fiber-guiding unit is moveable in a direction defined by connecting centers of the first winding reel and the second winding reel; and
iii) an air amplifier configured to suck in a plurality of hollow fiber membranes through a first aperture and eject the plurality of hollow fiber membranes through a second aperture,
wherein the air amplifier is configured to eject the plurality of hollow fiber membranes in a direction parallel to the axes of the first winding reel and the second winding reel.
