Abstract: A spindle for rotatably supporting a reel having both positive and frictional engagement between the spindle and the reel. The positive engagement is made at one end of the spindle, as by means of plural pins which engage plural recesses in the reel. The frictional engagement is made at the other end of the spindle and is provided by a radially expansible elastomer which is expanded by a locking arm. This dual engagement advantageously holds two-piece reels together as well as to the spindle.

Abstract translation: 用于可旋转地支撑在主轴和卷轴之间具有正和摩擦接合的卷轴的主轴。 在主轴的一端形成正接合，这是通过与卷轴中的多个凹部接合的多个销来实现的。 摩擦接合在主轴的另一端进行，并由径向可膨胀的弹性体提供，弹性体由锁定臂扩张。 这种双重接合有利地将两件式卷轴连接在一起，并且与主轴相连。
