The device comprises a succession of members in the form of plates collectively defining a path of traverse of the article to be turned, by means of apertures in the plates; each aperture being of the outline shape of the article and being angularly offset so that parts of each succeeding plate of the succession obstruct the path of the article incrementally to deflect the article as it passes through the aperture of each plate about an axis passing through the article and parallel with the path of traverse, thereby to change the orientation of the article. |
