    • A spool fixation device for use in a wire winding installation, where in this spool fixation device, spools having a magnetically attractable flange are held to a rotatable flange using magnet assemblies. The magnet assemblies can be switched between a ‘hold’ state and a ‘release’ state. In a preferred embodiment the magnet assemblies only consume energy when in the ‘release’ state i.e. when the spool fixation device is not rotating. Alternatively the magnet assemblies can be made to only consume energy when switching states. The magnet assemblies have permanent magnet arrays and are moveable inside a non-magnetic housing. Also a drive pin to transfer torque between rotatable flange and spool is no longer necessary. Therefore the spool fixation devices allows for a smooth changeover of spools.
    • 一种用于线缠绕装置的线轴固定装置,其中在该线轴固定装置中,具有可磁性吸引的凸缘的线轴通过磁体组件保持在可旋转的凸缘上。 磁体组件可以在“保持”状态和“释放”状态之间切换。 在优选实施例中,磁体组件仅在处于“释放”状态时消耗能量,即当线轴固定装置不旋转时消耗能量。 或者,可以使磁体组件在切换状态时仅消耗能量。 磁体组件具有永磁体阵列并且可在非磁性壳体内移动。 此外,不再需要在可旋转法兰和阀芯之间传递扭矩的驱动销。 因此,卷筒固定装置允许卷轴的平滑切换。
