Device for automatic handling of sheets of printing material

Device for automatic handling of in a sheet running direction (8) transported sheet (2) of printing material, with circumferential contact elements (14) which is temporarily in contact with each of the sheets (2) are provided and thereby with respect to the sheet running direction (8) are inclined, characterized in that the contact elements (14) of the sheet running direction (8) are rotatably adjustable in inclination in a position with respect to, in which the contact elements (14) apart by oppositely directed angle (+ α, -α, + β, -β) diverge.
