    • The invention relates to a winding shaft for winding a continuous flexible material web into a roll. The winding shaft has means in order to adjust the diameter of the winding shaft surface to be wound between a reduced-diameter unused position and an expanded operating position, and the winding surface in the expanded position is formed jointlessly with a uniform curvature and is supported inward against the operational pressure around said winding surface in a dimensionally stable manner that is substantially uniform. A roll can thereby be wound without disruptions and then stored without a casing until the roll "dies", said roll remaining stable during storage and not forming any disrupted zones on the inner face of the roll.
    • 本发明涉及一种用于将连续柔性材料幅卷成卷的卷绕轴。 卷绕轴具有用于调整缠绕轴表面的直径的装置,该卷绕轴表面的直径被卷绕在缩小直径的未使用位置和扩张操作位置之间,并且处于扩张位置的卷绕表面以均匀曲率无接缝地形成并且被支撑 以基本均匀的尺寸稳定的方式抵抗围绕所述缠绕表面的操作压力向内。 因此,卷可以不中断地卷绕,然后在没有外壳的情况下储存,直到卷“死”,所述卷在储存期间保持稳定并且不在辊的内表面上形成任何中断区。
