ABSTRACT:
Workpiece carriers are fed to successive work stations along conveyor tracks at which stations work operations are performed on individual parts on the carrier and in which a defect signal is allocated when appropriate. After a work operation has been performed a coding member is left in a normal switching position corresponding to a defect coding or displaced into a switching position corresponding to an accept coding if the work operations performed were satisfactory. In a coding device displaceable coding elements are supported by a workpiece carrier and traverse a detector device at the work processing station and a switching element for displacing the coding element from a reject coding switch position to an accept coding switch position. Advantageously an accept coding is only secured by a deliberate action when satisfactory work processing has been completed and thus subsequent processing of defective parts is avoided simply and with great reliability.
