Abstract
A feeding device transfers, one by one, sheets from a pile (12) to a processing device having a storage area for the pile of sheets, a drive roller (201) in contact with a sheet disposed at one end of the pile, a separating and prestressing device (203, 210) disposed opposite the roller, the separating and prestressing device including a friction device (203) generating, on the sheet, a friction opposite to the direction in which the sheet is driven. The separating and prestressing device (203, 210) also has a movable support (205) and a lever (211), the support (205) bearing the friction device, whilst the lever has at least one lateral prestressing arm (341), and an elastic unit (214) acting on the lever (211) in order to bias the surface towards the roller (201).
