    • A mandrel (300) suitable for supporting and unwinding a convolutely wound web material is disclosed. The mandrel (300) has a mandrel shaft (320) with a longitudinal axis (340), a plurality of mandrel arms (310) extending from the mandrel shaft (320), and at least one expansion element (330) disposed upon a respective each of the mandrel arms (310). The mandrel shaft (320) is capable of rotating about the longitudinal axis (340). Each of the mandrel arms (310) is disposed and rotatable about the longitudinal axis (340). The at least one expansion element (330) is expandable radially away from the respective mandrel arm (310) relative to the longitudinal axis (340). The convolutely wound web material is disposable about each of the mandrel arms (310). Further, the at least one expansion element (330) is expandable into contacting and releasable engagement with the convolutely wound web material. The convolutely wound web material is fixably and releasably disposed about each of the mandrel arms (310).
    • 公开了一种适用于支撑和退绕缠绕卷材的心轴(300)。 心轴(300)具有具有纵向轴线(340)的心轴(320),从心轴(320)延伸的多个心轴臂(310)和至少一个膨胀元件(330) 每个心轴臂(310)。 心轴(320)能够围绕纵向轴线(340)旋转。 心轴臂(310)中的每一个被设置并围绕纵向轴线(340)旋转。 至少一个膨胀元件(330)相对于纵向轴线(340)可径向地远离相应的心轴臂(310)。 卷绕卷材的卷绕材料围绕每个心轴臂(310)是一次性的。 此外,至少一个膨胀元件(330)可膨胀成与缠绕卷材的接触和释放接合。 卷绕的卷筒纸材料围绕每个心轴臂(310)固定和可释放地设置。
