A device whereby a pile of rectangular items is placed on an inclined surface and pushed towards the straight front edge thereof by a push unit. The surface presents two pairs of conveyor belts parallel to each other and coplanar with the surface; and the pile is arrested upon a bottom portion of the first item in the pile activating a first or second limit stop sensor, which activates a, respective pair of belts so as to move the bottom left or right portion of the item and so orient the item in relation to a gripping plane. A gripping unit with two suction cups movable along a three-dimensional trajectory grips the oriented item and feeds it to a follow-up conveyor belt.

Why it's free to use
- Filed July 21, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 21, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
