    Improved packaging method and device. Technical field
    The invention belongs to the technical field of the packaging of stacked compressible products in a stable manner, in particular the packaging of disposable absorbent articles such as diapers, which are used in e.g. open cartons can be prepackaged that are stacked on a pallet.
    Background
    Consumer items such as baby diaper bags are often packed in tray cartons, stacked on pallets, fitted with edge protectors and packed with a stretch film.
    For example, WO 1996/041753 Al discloses a package consisting of a series of at least two substantially rectangular flexible suits.
    However, the prior art packages require large amounts of stretch film, they require the use of expensive edge protectors and often do not have sufficient stability, often at the expense of transport safety and logistical handling. The use of inexpensive repackaging materials such as tray cartons or so-called shelf-ready packaging cartons that typically feature recovery openings show various drawbacks.
    There remains a need in the art for an improved packaging method and apparatus to solve at least some of the aforementioned problems.
    The invention therefore seeks to provide a package that improves the stability of the packages (e.g. baby diaper cartons on pallets) at the same time significantly reducing the need for stretch film and edge protectors.
    Summary of the invention

    The invention provides an apparatus and method for stabilizing stacked products using two different materials, preferably provided as a banderole or sleeves.
    These materials can consist of very different physical properties. To stabilize a load of this kind, it is common to package a pallet of stacked units with a film 6. This film is wound on roll 2 and can be unwound as it is wrapped around the stack. A typical width of the film is 500 mm. This can be done using the functionality of the turntable stretch winding machines or the rotary arm or ring stretch winding machines.
    As this usual method of load securing, a banderole / sleeve of a rolled sheet of film 6 of film roll 2 is common, showing a high degree of elasticity and high resilience.
    The object of the present invention is to stabilize stack 5, wherein the individually stacked units or products show a low degree of resistance to deformation, with a highly resilient stretch film, without significantly deforming units.
    A further object of the invention is to provide a way to secure cargo, thereby preventing the detachment of individual products from the assembly and their breakthrough of cargo security.
    A further object of the invention is to provide charge security thereby preventing individual units or products from losing their height due to their compressibility.
    The invention is further described by the following non-limiting examples that further illustrate the invention, and are not intended, nor should they be construed, to limit the scope of the invention.
    EXAMPLES
    The invention is illustrated in Figs. 1 and 2, which shows a roll 1 of the first material of a draw belt roll / sleeve, a roll 2 of a second material of a conventional packaging film, a turntable 3 of a conventional packaging machine, a support arm 4 for supporting roll 1 of the first material and roll 2 of the second material, a stack 5 of products or pre-packaged units of products on a pallet, the width 6 of the conventional delivery 7 of the second banderole to the package and the width 8 of banderole of the second material.
    According to the invention, a second material is provided as a banderole or sleeve that can be unrolled from a roll 2 of a packaging device.
    According to the invention, the width of second banderole / sleeve 8 is wide enough to enclose a specific layer of products or prepackaged units of products, or several product layers or unit layers at the same time.
    According to the invention, a more stretchable material (e.g., kraft paper) is wound on a second roll 2. The material is then attached to the pallet over a feed means of transport 7. The material is then clamped between the material and the package. The rotation of turntable 3, the rotating arm, or the ring causes material 8 to be taken along. After a randomly determined cover count, the turntable 3, the rotating arm or the ring stops. Material 8 can then be cut manually or in an automated manner.
    Due to the high tensile strength of the second winding material / sleeve material, the pallet develops an increased resistance to lateral load such as that which occurs due to inertia forces in transport.
    It is believed that the present invention is not limited to any previously described form of realization and that some changes may be added to the proposed example of manufacture without revaluing the appended claims.
