The production method for hollow fiber membrane bundles is a method that produces hollow fiber membrane bundles composed of many hollow fiber membranes and having a cylindrical shape overall by stacking many hollow fiber membranes. In this production method, there is a winding process in which each hollow fiber membrane is moved back and forth axially on a cylindrical body while being wound around the axis of the cylindrical body. In the winding process, each hollow fiber membrane is turned back toward both one end and the other end of the cylindrical body to form turned-back sections, and an anchoring fiber, while being wound around the axis of the cylindrical body, is overlaid near a turned-back section to anchor the turned-back section. |
