发明名称 YARN CONES
摘要 Yarn cones of hollow tapered configuration for supporting yarn at an exterior surface of the cones. The yarn cone has opposed ends one of which is smaller than the other and at the smaller end the yarn cone carries an annular member which projects axially from the smaller end of the cone. In this way when identical cones of this construction are nested the annular member of one cone will engage the smaller end of the body of an adjoining cone to limit the extent of nesting of the cones and thus prevent them from becoming wedged to each other.
