Device for count of blattfoermigen objects, in particular bank notes

摘要

The suction shaft (12) is provided with a curved suction surface (13) having its centre of curvature in a plane perpendicular to the axis of rotation of shaft (12). Shaft (12) has an opening formed in the curved suction shaft (13) communicating with a vacuum pump, through the interior of the shaft (12). A flat surface (15) is formed on the suction shaft (12) at an angle to the curved suction surface (13) to intersect the curved suction surface at its tail or trailing edge (12'). When suction is applied through the opening to the foremost paper (5) of a pile to draw it against the curved suction surface (13) on the suction shaft (12), the sucked paper (5) will be curved longitudinally. Then, the paper (5) is folded by the tail edge (12') of the suction surface (13) in a direction perpendicular to the centre of curvature.
