Abstract
This disclosure relates to a magnetic system for controlling the rotational orientation of workpieces during the moving thereof from one work station to another. A magnetic sensing line is applied to the workpiece immediately adjacent the first work station and thereafter it is sensed adjacent the second work station where a workpiece found to be improperly oriented is either ejected or rotated.

Method for ascertaining whether a ferromagnetic cylindrical workpiece having an axis and being conveyed generally axially along a path of travel from a first work operation to a subsequent work operation has rotated about its axis away from the position assumed in the first work operation comprising the steps of in connection with the first work operation applying an axial magnetic track on the workpiece with a certain rotational placement about the workpiece axis in relation to a selected site where the first work operation is performed on the workpiece, and in combination with the subsequent work operation detecting the magnetic track on the workpiece by magnetism detecting means that have the same rotational placement with respect to the workpiece axis relative to the selected site of the first work site.
