    • A button support 53 is upwardly biased and is movable along a vertical axis between three positions. Buttons formed with at least two thread holes are orientated by rotary frictional drive means 60 and 61 through effecting relative rotation between the button support 53 and a button 101 which are located by positioning means 13 and 18 positioning a button above the button support. In the lowest position of the button support, the button support is free to rotate about the vertical axis relative to a button 101 located by the positioning means 13 and 18. In an intermediate position the button support together with the button located by the positioning means 13 and 18 are rotatable about the vertical axis. Pins 54 project upwardly from the button support 53 for insertion in the holes of the button so that the button and button support can rotate together. In an upper position, the button support is locked against further rotation so as to provide a support for buttons in the required orientation.
    • 按钮支撑件53向上偏置并且可沿着三个位置之间的竖直轴线移动。 形成有至少两个螺纹孔的按钮由旋转摩擦驱动装置60和61定向,以通过定位装置13和18定位按钮支撑件上方的按钮而定位在按钮支撑件53和按钮101之间的相对旋转。 在按钮支撑件的最低位置,按钮支撑件相对于由定位装置13和18定位的按钮101围绕垂直轴线自由旋转。在中间位置,按钮与由定位装置定位的按钮一起支撑 13和18可以围绕垂直轴线旋转。 销54从按钮支撑件53向上突出以插入按钮的孔中,使得按钮和按钮支撑件可以一起旋转。 在上部位置,按钮支撑件被锁定以防止进一步旋转,以便为所需取向中的按钮提供支撑。
