ABSTRACT The invention has for its purpose to provide a method and an apparatus for inspecting the bent edge of a disc-shaped object, e.g. the annular edge of a metal lid bounding a gutter for sealing compound. In order to realize such an inspection with great reliability according to the invention the resolution is made as great as possible by means of the following steps: (2) directing a light beam onto the edge zone of the object under an angle of incidents, such that the bent edge gives a shadow in said edge zone; (3) previously determining the shape of the reflection picture also determined by said shadow of said illuminated edge zone in case of an object satisfying a predetermined standard; (4) determining the reflection picture of the edge zone of an object to be inspected; and (5) comparing the results of steps (4) and (3) and generating a rejection signal in case of a detected deviation lying outside a previously chosen tolerance range.
