Abstract:
Apparatus for detecting surface flaws in cylindrical articles having central longitudinal axes, including a guide assembly for guiding the cylindrical articles along a displacement path having a central longitudinal axis extending coaxially of the central longitudinal axes of the articles and a detection coil assembly positioned in annular relationship with the displacement path for producing a signal representative of the surface geometry of a cylindrical article which traverses the displacement path.
