Abstract:
An apparatus for the separation of sheets comprising:a transport structure for exerting a force on an outermost sheet of a pack of sheets in a direction of transport substantially parallel to said sheet; a separation structure for exerting a force on at least one other sheet of said pack against the direction of transport to prevent said at least one other sheet from moving along with said outermost sheet in the direction of transport, said sheets overlapping each other, at least the transport structure or the separation structure having a surface suspended for exerting a force with a normal force component transverse to said outermost sheet and a frictional force component parallel to the direction of transport, said surface possessing a frictional coefficient; a treating device for treatment of said surface of the at least one of the transport structure and the separation structure to increase the frictional coefficient of said surface; and an applicator for applying a liquid onto said surface.
