Inline Model SO-4 is designed to accept and convey rectangular, square, and round bottles with centered necks and/or handles. It distinguishes bottle’s incoming orientation based on container symmetry using variety of inspection methods, and orients bottles accordingly. Self-contained, free-standing unit can orient 90, 180, and 270 deg, depending upon inspection results. Hand-crank or electric height adjustment allows unit to be raised when not in use and lowered for next changeover.
