摘要： A winding core member of a winding core is divided along an axial direction into a first main body, a second main body and a third main body. Projections which are formed at the respective main bodies can fit into cam grooves of cams provided in the winding core member. For this reason, when the cams are rotated, inner peripheral walls of the cam grooves are engaged with the projections, and the main bodies are pulled in inwardly in a radial direction so as to approach each other, so that an outer diameter of the winding core is decreased. Therefore, after a sheet material is or sheet materials are wound in layers around an outer periphery of the winding core, the winding core can be pulled out from the sheet material(s) easily.
摘要翻译：卷芯的卷绕芯部件沿轴向分为第一主体，第二主体和第三主体。形成在各个主体上的突起可以装配在设置在卷芯部件中的凸轮的凸轮槽中。为此，当凸轮旋转时，凸轮槽的内周壁与突起接合，并且主体沿径向向内拉动以使彼此接近，使得绕组的外径核心减少。因此，在薄片材料或片材材料围绕卷芯的外周缠绕成层状材料之后，卷绕芯能够容易地从片材中拉出。
