    • An improved turret for use in winding and unwinding operations in which each of the arms of two pairs of generally diametrically oppositely extending roll supporting arms is eccentrically mounted on the cross-shaft by linear bearings which permit rolling movement of an arm axially of the cross-shaft while constraining the arm to rotate with the shaft. Respective independently operable means associated with each pairs of arms permit the arms of a pair to be moved concomitantly axially toward or away from each other to accommodate different roll widths. Other independently operable means permit the arms of a pair to be moved together axially from side to side to adjust side lay of the web being handled.
    • 一种用于卷绕和退绕操作的改进的转台,其中两对大致直径相对延伸的辊支撑臂的每个臂通过直线轴承偏心地安装在横轴上,允许臂的轴向滚动运动, 同时约束臂与轴一起旋转。 与每对臂相关联的各自可独立操作的装置允许一对臂相互轴向地相互移动或相互移动以适应不同的卷宽度。 其他可独立操作的装置允许一对的臂从一侧到另一侧轴向移动,以调整正在处理的幅材的侧面布置。
