Rubber thread (5) is wound on a center (4) to form a wound core by grasping the center (4) with grasping fingers (23), locating the center (4) among rotatable winding rollers (12), securing a leading end of rubber thread (5) to the center surface by means of a capture finger (24), rotating in this state the center (4) together with the grasping and capture fingers (23 and 24), thereby winding the rubber thread on the center, bringing the winding rollers in pressure contact with the center surface through the rubber thread, thereby holding the center (4) and the rubber thread thereon by the winding rollers (12), withdrawing the grasping and capture fingers (23 and 24) from between the center (4) and the rubber thread (5), and driving the winding rollers (12) for rotating the center, thereby further winding the rubber thread on the center (4). The winding method can firmly secure the leading end to the center without a need for adhesive or water, and it can be fully automated.
