  • the generic method has proven especially for the formation of packaging units of stacked bags.
  • Such a packaging unit of stacked bags is repeatedly handled during the formation and transport, wherein between adjacent stacked bags Setzbeträge occur. These set amounts are the higher, the more bags are arranged on one level and / or the higher the weight of a single bag.

  • the retaining layer preferably has a rectangular envelope surface within which said indentations are located. The indentations are preferably chosen such that their bottom, i. the innermost point lies on a rectangular envelope, which corresponds to the base of the stack of goods.
  • the identity between the inner envelope and the base of the stack is given even if a 3 to 10% ige deviation between the base of the stack and the inner envelope surface shows.
  • a contoured holding layer improves the strength of the wrapped product stack, since in such an embodiment preferably provided at the respective corners Garlagenzipfel come to rest on the vertical edges of the stack after it has been covered with a stretch hood. At these edges may be due the higher elastic elongation of the stretch hoods against the stack good anchoring of the holding position can be effected.
  • the previously discussed special holding position in the form of a contoured holding position can also be essential to the invention. Their advantages also arise when only one holding position is provided. Preferably, both of the mutually perpendicular to the stack of goods stored holding layers corresponding contouring.

This is particularly important if the material of the flat web has an anisotropy. Anisotropy in this sense means that different mechanical properties result depending on whether the film is drawn in the longitudinal or in the transverse direction.
  • both retaining layers overlap in the corner regions of the uppermost normal position.
  • the overlapping areas at all four corners of the uppermost normal position which can be achieved solely by the areal extension of the holding layers or else by targeted folding of the holding layers are pressed together by the elastic hoop stress of the hood. It creates an all-round protection that includes at least the upper normal position partially, as well as includes the special situation.

  • the present invention further proposes a packaging unit having the features of claim 4.
  • This differs from the generic state of the art in that a second holding layer is arranged between the first holding layer and the first film and at least partially is applied to packaging items of special situation, each forming a side surface of the packaging unit.

  • the first and / or second retaining layer comprises a lattice-structure-reinforced film web in order to increase the stability of the packaging unit as a whole.
  • the first and / or second holding layer comprises a film web with a woven structure in order to increase the stability of the packaging unit.

  • the gripping device can be moved over the stack of goods on a path perpendicular to the travel path of the stack, in order to pull the film above the stack of goods provided when the clamping jaws 23a, 23b are open. In this position, when the jaws 23a, 23b are closed, a knife 25 cuts through the material between the two jaws 23a and 23b.
  • a lifting frame 27 carrying at least four clamping elements 26a-d is provided above the separated flat track.
  • the lifting frame 27 is lowered so far that the clamping elements 26a-d take over the holding of the film by each two clamping elements in the region of the respective front and rear ends of the flat track each hold a side edge.
  • the means for separating a lifting device 28 After releasing the separated film web from the means for unrolling and the means for separating a lifting device 28 lowers the lifting frame 27 so far that the film web 20 is placed on the stack, whereupon the Clamping elements 26a-d of the lifting frame 27 are opened and release the flat track, which then lays on the stack.
  • the lifting frame 27 is rotatable by 90 ° about the Leksache of the stack 1 by means of a rotating device to hang up a second flat web transversely to the first flat web.
  • Fig. 10 shows a plan view of the schematic device according to Fig. 9 ,
  • the lifting frame 27 is H-shaped.
  • a rotation axis 29 lies in the center of gravity of the lifting frame 27.
  • the clamping elements 26a to 26d are respectively arranged at the distal ends of the free legs of the frame.
  • the knife 25 is arranged on a device for moving, such that it is guided in the display plane from top to bottom between the jaws 23 a, 23 b along.
  • the gripping members 24a, 24b are shown in the left position in receiving the free end of the sheet material. After the process in the illustration to the right and transverse to the direction of passage of the stack of goods, the gripping elements 24a, 24b are located on the opposite side of the stack of goods.
  • the passage direction of the stack is in this illustration from top to bottom or from bottom to top.
  • the lowering of the lifting frame 27 takes place in this view in the plane.
  • FIG. 11 shows an embodiment of a preferably to be used holding layer 8, which is cut from an initially rectangular sheet material.
  • dashed line illustration shows FIG. 11 the contour of the stack 1 in plan view, ie the base of the stack 1.
  • the retaining layer 8 has four recesses designated by the reference numerals 30 and 31.
  • the larger indentations 30 are recessed on the larger longitudinal sides of the retaining layer 8.
  • the smaller indentations 31 at the right angles to this extending longitudinal sides.
  • the larger indentations 30 each have a depth A, which corresponds to central stack of the retaining layer 8 on the stack 1 at a distance of the imaginary extension of the longitudinal side of the stack 8 of the associated side surface of the stack 1.
  • the depth D of the smaller indentation 31 corresponds to the distance of the imaginary extension of the respective longitudinal side of the holding layer 8 from the longitudinal side of the product stack 1 extending parallel thereto.
