Abstract
For powdering printed products it is proposed that they be moved through a nip formed by a powder application roller (38) and a support roller (32). Those two rollers have axial circumferential recesses (52, 54) which are each able to receive at least part of a gripper rod (24) moving a printed product and which are synchronized with the movement of a gripper rods. At a location upstream of the nip in the direction of rotation, powder is applied to the circumferential surface of the application roller (38) by a nozzle strip (62), which powder is then transferred in the passage nip from the application roller to the printed products.
