ABSTRACT:
A machine is disclosed for inspecting the profile and wall of a bottle which is delivered by a conveyor sequentially to two inspection stations. A pair of light sources, when fully illuminated, define two images of the bottle on a CCD camera image, so that the wall can be inspected. Portions of the light sources are darkened so that two different images of the bottle will be imaged on the CCD camera image so that the profile can be inspected.
