摘要： A package holder for use in winding yarn packages comprises at least one arm adapted to support a bobbin tube and pivotable about a first axis as a yarn package is formed on the tube. The arm is also pivotable about a second axis extending transversely to the first axis to make it possible to install or remove the bobbin tubes or packages. A first member is provided which is movable with the arm during the pivoting movement thereof about the first axis. A second member is engaged by the first member and is so mounted that relative movement of the first and second members occurs during the pivoting movement of the arm about the first axis. The zone of contact between the first and second members either includes or passes so close to the second axis that the forces acting between the first and second members have no or only negligible effect on the pivoting about the second axis, or a biassing arrangement for pivoting the arm about the second axis compensates for the effect of any offset of the zone of contact relative to the second axis on such pivoting about the second axis.

摘要翻译： 用于卷绕纱线包装的包装保持器包括至少一个臂，其适于支撑筒管并且可绕着第一轴线枢转，因为在管上形成纱线包装。 臂也可以绕横向于第一轴线延伸的第二轴线枢转，以使得可以安装或移除筒管或包装。 提供第一构件，其在与第一轴线枢转运动期间可与臂一起移动。 第二构件由第一构件接合并且被安装成使得第一和第二构件的相对运动在臂围绕第一轴的枢转运动期间发生。 第一和第二构件之间的接触区域包括或穿过如此接近第二轴线，使得在第一和第二构件之间作用的力对围绕第二轴线的枢转没有或仅可忽略的影响，或用于枢转的偏置装置 围绕第二轴线的臂围绕第二轴线的这种枢轴补偿接触区域相对于第二轴线的任何偏移的影响。
