ABSTRACT:
Apparatus for inspecting lean of a container includes a light source positioned beneath a container for directing light energy onto the container bottom as the container is held in position and rotated around an axis. A light sensor positioned beneath the container receives portions of the light energy from the source reflected from the container bottom. An information processor is coupled to the light sensor for determining, as a combined function of the reflected light energy and container rotation, departure of the container bottom from a plane perpendicular to the axis. The container preferably is held in position and rotated around an axis by a drive roller that urges the container against axially spaced backup rollers so as to define an average axis of rotation as a function of the geometry of the container and spacing between the backup rollers.
