Abstract: The invention is a centerwinder for receiving and winding web material sequentially on one of at least two fixed shafts. The two or more shafts are desirably positioned vertically to one another in a stationary structure and eliminate the need for a powered turret assembly. A lay-on roll assembly can be used that pivots in and out as well as up and down for serving the respective shaft locations. A cylinder linkage provides the same or constant force against the winding roll on either the upper or the lower shaft. Transfer rolls in desirable embodiments are automatically pivoted into the proper position for a fully automatic transfer or to assist the operator during a manual cut and transfer.

Abstract: An improved turret type winder incorporates articulated constant contact lay-on rolls mounted concentrically with chucks at the ends of the arms of the turret winder. The articulated constant contact lay-on rolls are continuously repositioned radially during winding and are able to either maintain constant pressure or to reduce lay-on roll pressure as the film bundle diameter increases. Web tension variations during transfer operations are minimized by maintaining an essentially constant wrap angle on the lay-on roll between the web and the lay-on roll. An improved web feed-in mechanism is incorporated to reduce web tension variations due to drag forces. An improved method for winding film bundles is also provided whereby the nip pressure is varied during winding and then maintained at an about constant value during turret rotation.

Abstract translation: 改进的转塔式卷绕机将铰接的恒定接触式铺装辊与卡盘同心地安装在转塔卷绕机的臂的端部。 铰接的恒定接触辊在卷绕过程中径向连续重新定位，并且能够保持恒定的压力或者随着膜束直径的增加而降低轧辊压力。 通过在幅材和铺放辊之间的铺展辊上保持基本恒定的包角来最小化转印操作期间的纸张张力变化。 引入改进的卷筒纸进料机构以减少由于牵引力引起的卷筒纸张力变化。 还提供了一种用于卷绕膜束的改进方法，其中辊隙压力在卷绕期间变化，然后在转塔旋转期间保持在约恒定值。
