Abstract (en)

[origin: EP0387476A1] In conjunction with an apparatus for seizing flat sheets on a stack of sheets arranged on a supply table (1), a sheet-separating device (10) is characterized by an air flow generator (15) and guide means (A,B) designed to direct a turbulent air flow produced by said generator (15) on at least one side of the stack of sheets. The guide means comprise, for example, a first tube (A) arranged so as to direct a flow of air produced by said generator (15) onto one side of the upper part of the stack of sheets (100) placed on the supply table (1) and a second tube (B) for directing an air flow produced by said generator (15) in the upper part of the free space (8) located under the sheet-seizing device (2).
