The Padding Element is created by two synthetic foil runs (1, 2) arranged one over the other and which are connected by means of first welding seams (3) and second welding seams (4). In each case two adjacent first welding seams (3) and second welding seams (4) create a chamber which during the manufacturing process of the Padding Element can remain unfilled with air, be partially filled with air, or completely filled with air, as required. In this manner Padding Elements can be produced with configurations individually adaptable to the object to be packed (6). The Padding Element is preferably used for at least three-sided enclosure of the object to be packed (6) and comprises, rather like a book cover, a top cover (7), a back (9) and a bottom cover (8). The Padding Element offers the advantage of requiring little material to create appropriately configured packing elements, with all the corresponding benefits, whereby space-saving disposal after use is effected by slitting open the air-filled chambers. As it is intended to produce the Padding Elements on a Device installed close to their place of use, on an as-required basis, storage space requirements for packing material will be practically negligible.
Padding element for the packaging of objects, comprising two synthetic foil layers arranged one over the other and joined by means of welding seams, the welding seams comprising at least two adjacent first and at least two adjacent second welding seams which intersect, wherein each two adjacent first welding seams and each two adjacent second welding seams are sealed along lengths and widths to enclose corner-shaped chambers, at least one of the chambers being partially filled with air, and wherein cutoff lines are provided at least between said two adjacent first welding seams, the cutoff lines extending over the length of the adjacent chambers.
Device for the manufacture of a padding element, comprising at least one contrivance for synthetic foil feed and one contrivance for synthetic foil welding, wherein the contrivance for synthetic foil welding comprises a first welding station which applies first welding seams running longitudinally to a synthetic foil run, followed by a second welding station which applies second welding seams approximately at right angles to the first welding seams, wherein the first welding station has several welding rods arranged essentially parallel to one another, a cutoff contrivance being disposed at least between two welding rods of said several, wherein two first and two second drive rollers are installed in front of the first welding station as well as in front of the second welding station to conduct foil runs and wherein air feed tubes are provided, running from in front of the first drive rollers to after the second drive rollers in a longitudinal direction to the synthetic foil runs, one each of the air feed tubes running between two each of the adjacent welding rods.
