Device for packaging an object in foil wherein a pair of foils are disposed on both sides of a packaging plane and, in a central welding device, are welded to one another enclosing therebetween the object to be packaged, and wherein the foil webs travel in a given direction and, for each foil web, a foil-web parting and/or foil-web re-welding device is provided, serving to effect an exchange of foils and having functional members for parting a foil web as well as for welding a pair of juxtaposed foil-web ends together, the functional members extending transversely to the foil-web travel direction, the parting and/or re-welding device being disposed between a bearing which carries one foil roll, and a foil-web pullng device located upstream of the central welding device in the foil-web travel direction, includes at least another bearing carrying a foil roll disposed in spaced relationship to and behind the first-mentioned foil-roll bearing, means defining respective separate foil-web guide paths for the foil webs of each of the foil rolls, the guide path means having at least one conveyor device and extending from the foil-roll bearings to the vicinity of the parting and/or re-welding device, the separate guide paths having respective end regions at the vicinity of the parting and/or re-welding device, the end regions being disposed slightly spaced for one another at varying elevations.
