Abstract: A method for detecting mispositioned parts in assemblies of parts wherein the orientation of one of the parts of an assembly of parts is to be controlled relative to at least one other part in the assembly of parts. The method includes applying a lightreflective-marking pigment to a part whose orientation is to be controlled. The marking pigment is applied to the part at a time when its orientation is known and prior to its assembly with at least one other part of the assembly of parts. An examination of assembled parts is made by a light-sensing device, and by the response of the light-sensing device to the presence or absence of light reflected from the marking pigment, mispositioned parts in the assembly of parts are detected. In particular, the method disclosed is applicable to checking the orientation of storage battery cell elements in their containers.
