摘要： An apparatus and method is disclosed for winding a web about a central axis and a rotating mandrel to form a roll. A rolled web product with an alternating winding pattern may be manufactured. A feeding mechanism provides a running web to be wound into a roll. A retainer assembly may be configured for holding the web as it is wound upon the rotating mandrel. The retainer assembly may be configured to accommodate oscillating movement of the rotating mandrel between a clockwise and a counterclockwise direction. The web may be placed upon a roll by winding in one direction and then back again in a second direction repeatedly to form a roll. Retaining means, such as paddles, may be actuated from an active position in contact with the web to a resting position removed from the roll. Paddles may serve to hold the web upon the outer surface of the roll at the time in which the rotating mandrel is changing rotational direction.
摘要翻译：公开了一种用于围绕中心轴线和旋转心轴缠绕卷材以形成卷的装置和方法。可以制造具有交替卷绕图案的卷材产品。进给机构提供卷绕卷筒的运行卷筒纸。保持器组件可以被配置用于当卷筒卷绕在旋转心轴上时保持卷筒纸。保持器组件可被构造成适应旋转心轴在顺时针和逆时针方向之间的摆动运动。纸幅可以通过沿一个方向卷绕而放置在卷上，然后再次在第二方向上反复地形成卷。诸如桨叶之类的保持装置可以从与幅材接触的活动位置致动到从辊移除的静止位置。在旋转心轴正在改变旋转方向的时候，桨可以用于将卷材保持在辊的外表面上。
