Abstract: A tippet spool is self-orientating when displayed on pegs at retail. The tippet spool also has structures adapted to interlock adjacent tippet spools in a stack with one spool rotatable with respect to its neighbors. The tippet spool is self orientating because of an asymmetrical central opening with the center of mass of the tippet spool opposite the portion of the central opening furthest from the center of the spool.
Abstract translation: 当在零售店铺上的钉子上显示时,一个尖头线轴是自动定向的。 提升销轴筒还具有适于将堆叠中相邻的尖端卷轴互锁的结构,其中一个卷轴可相对于其邻近物旋转。 由于不对称的中心开口,提升滑阀是自动定向的,其中提升滑阀的质心与中心开口的最远离滑阀中心的部分相对。
