Abstract
A method for producing bound books, magazines or brochures by gathering printed sheets into non-bound book blocks along a conveying section that is supplied by at least one sheet feeder includes separating the lowest printed sheet from a stack of printed sheets by lifting one edge region of the lowest printed sheet from the bottom of the printed sheet stack, withdrawing the separated lowest printed sheet with the aid of a conveying element from the remaining sheet stack by gripping the separated edge region with the conveying element, and subsequently withdrawing the separated lowest printed sheet in a direction parallel to the longitudinal extension of the edge region of the remaining sheet stack. The apparatus includes a separating device that lifts up the printed sheet at the stack front and a conveying element that pulls the printed sheet from the stack where both are arranged jointly on a removal unit.
