A device and a method are provided for packaging flat objects into a packaging material web (110). The device includes a conveyor device (30) with an essentially plane conveyor surface (34) which is capable of conveying the flat objects (100) one after the other and distanced to one another in a conveyor direction (F). Moreover, at least one processing tool (10) with a processing-active zone (12) is present. The processing tool (10) is capable of processing the packaging material web (110) in the region between two objects (100) in a processing region (B) of the device (1). Thereby, the packaging material web (110) covers the objects (100) on both sides. The processing tool (10) is movable for processing at least perpendicularly to the conveyor surface (34).
