Abstract

Apparatus and method of gauging the "saddle" of a container finish in which a test rig supports a bottle or container at an elevated position so the container can be rotated about the axis of its finish. The container is threaded into a finish ring. The finish ring is accurately supported for rotation in a horizontal plane with the feeler of an indicator engaging the top rim of the container during rotation. 360.degree. rotation in both directions gives maximum and minimum readings that are registered and used to determine the differential or saddle of the container.
