Abstract

A method and a device for inspecting the surface of spherical balls by using known optical and electrical sensors which are positioned on a quickly rotating sensor spindle. The novel feature resides in that the ball is rotated about one turn mechanically about a first axis of rotation (A-A) which suitably is at right angles to the axis of rotation of the sensor spindle and that thereafter the ball is rotated about one turn mechanically around another axis of rotation (B-B) at right angles to the other axes. During both rotations the sensor spindle is rotated and scans the ball surface.
