Abstract: Automatic taking-up of a long member is enabled to reduce man-hour etc., needed for take-up operation to improve the productivity in the production of the long member. A take-up device (1) for a long member (50) includes a take-up reel (10), rotation driving means that rotates the take-up reel (10), guide means (20) that guides the long member (50), and a control unit (30) that performs control of the entire device. An insertion portion (13) into which the end portion of the long member (50) can be inserted is formed in the core member (11) of the take-up reel (10). Rotation of the take-up reel (10) is controlled by the control unit (30) to set the opening of the insertion portion (13) at a predetermined position. The end portion of the long member (50) is guided toward that position by the guide means (20), and the end portion is inserted through the insertion portion (13). Then, the take-up reel (10) is rotated to take up the long member (50) on the core member (11).
