A device for conveying and cutting a pile of sheets comprising: a frame; a conveyor for feeding the pile of sheets in a conveying direction, said conveyor including a first conveyor element having a convex cylindrical circumferential surface and being mounted on said frame for rotation of said cylindrical surface around an axis extending at right angles to said conveying direction and a second conveyor element forming an endless belt having an endless circumferential surface, deflecting means for mounting said endless belt on said frame for revolution along an endless path around an axis of revolution parallel to said axis of rotation, so that a portion of said belt is deflected by a segment of said cylindrical surface of said first conveyor element, first and second endless conveyor surfaces supported by said segment and said portion of said belt, respectively, and defining a clamping gap there-between for clamping the pile of sheets and for conveying the pile of sheets along said gap; a disk-knife rotatably mounted about an axis parallel to said axis of revolution, said disk-knife having two sides, one of said sides having a rim, said rim being surrounded by a circular cutting edge, at least said rim of said one side and said cutting edge defining a common plane, said plane extending at right angles to said axis of rotation; and first drive means for driving at least one of said conveyor elements and second drive means for rotating said disk-knife; said first and second conveyor surfaces having edges, said conveyor being arranged so that a portion of said planar rim and said cutting edge overlaps said edges of said first and second conveyor surfaces, said edge of said first conveyor surface being in contact with said cutting edge and said edge of said second conveyor surface being located adjacent said cutting edge, so that said disk-knife and said first conveyor surface constitute a cutting device for cutting a pile of sheets clamped in said clamping gap adjacent to said cutting edge.
