ABSTRACT:
A device and a method are disclosed for identifying overlaps of flexible flat items being moved along a conveyance path in a conveyor segment which is configured to move the items sequentially while the items are standing on edge and such that at least one section of each of the items is deflectable perpendicularly with respect to the conveyance path. A deflection element is disposed adjacent the conveyor segment for temporarily deflecting a section of the flat items perpendicularly with respect to the conveyance path by a predetermined amount while the items are being conveyed. Each deflection element is associated with a detection device which detects an overlapping of the items based on a flip-back behavior of the temporarily deflected section of the items.
