Definitions
- Photographic paper is often used in the form of large rolls, the width of which Corresponds to the width of the desired image format, e.g. 7, 10, 13 cm etc.
- the roles are packed light-tight. To use them, they are usually put in one Cassette inserted, which is connected to the processing machine. To everyone To avoid pre-exposure, even at the edges of the image, the paper roll must be inserted into the cassette while removing the packaging material in the dark become.
- the photo paper is wrapped on a round paper tube.
- On the right and on the left a round, opaque one that corresponds to the size of the roll Flange which has a round opening in the middle corresponding to the sleeve, attached and welded along its opening to the sleeve edge.
- An opaque one Mantle length is sealed to the end of the photo paper to make the photo paper wrapped and welded at their edges to the round edges of the flanges.
- the outer jacket is pulled out the opening of the cassette protruding end of the jacket from the flanges loosened at the welds and pulled out of the cassette. Then the cassette docked to the copier and copying can begin.
- the material for the flanges is made up of several layers:
- an approximately 130 ⁇ m thick paper layer is provided as a support; following at least one black-colored layer as a light barrier, at least one aluminum layer as a vapor barrier, at least one layer that the puncture resistance raised and furthest from the paper backing a layer that is sealing made possible with the jacket or the paper sleeve.
- the ones following on paper Layers together have e.g. a thickness of 120 ⁇ m.
- This packaging fulfills all requirements for easy handling, Luminosity and resistance to puncture, but shows one serious disadvantage, because with certain exposure machines (printers) fall, when the photo paper is largely unrolled, follow the outer areas of the flanges inside and are also wrapped when rewinding the photo paper. Apart from Possible damage is the winding diameter of the photo paper rolls larger than the corresponding paper length. For printers with a residual length determination faulty remaining lengths are then reported.
- the object of the invention was to avoid this disadvantage.
- This object is achieved in that on the outside of the paper carrier of the flanges e.g. 20 to 60 ⁇ m thick layer of a synthetic polymer applied by extrusion becomes.
- This layer which is preferably made of polyethylene, gives this Material a tension that prevents the flange from collapsing inwards.
- the plastic layer is preferably 30 to 50 ⁇ m thick and consists of HDPE (high density poly ethylene).
- a heat-resistant layer is added to the polymer layer Varnish applied to melt the polymer layer during welding to prevent the flange and the jacket from becoming.
- Research Disclosure 22 932 describes a flange that is a laminate of paper, Aluminum and polyethylene is the second side of the paper no further is laminated.
- EP-A-350 093 describes a laminate of paper, aluminum, black polyethylene or polyethylene terephthalate, aluminum and black polyethylene. Again is the other side of the paper is not laminated.
- FR-A-12 90 447 describes paper laminated on both sides with polyethylene.
- EP-A-444 611 describes a packaging for a film cartridge, according to column 10, Lines 28 through 42 form a paper tube and a cap, the tube (see Figures 19 to 21) from several successive layers of paper, LDPE and HDPE, while the cap is also made of paper that is on only one side is coated with different layers.
- US-A-2 797 804 describes a laminated disc (comparable to a flange) with an inner sticky layer on the web edges of the rolled up wrap of photographic material. According to Figure 7 follows on a paper support for this laminated pane a PE layer, then a film, then another PE layer. The other side of the paper remains uncoated.

Claims (3)
- Tageslichtverpackung für fotografisches Papier in Form von Rollen bestehend aus seitlichen kreisförmigen Flanschen und einer mit den Flanschen verschweißten Mantelallonge, die an einem Ende mit dem Anfang der Papierrolle verbunden und am anderen Ende frei ist, wobei die Flansche ein konzentrisches, kreisförmiges Loch aufweisen, dessen Rand mit dem Rand der Rollenhülse verschweißt ist und die auf einer Seite eines Papierträgers wenigstens eine schwarz eingefärbte Schicht als Lichtsperre, wenigstens eine Aluminiumschicht als Dampfsperre, wenigstens eine Schicht, die den Durchstoßwiderstand erhöht und am weitestens vom Papierträger entfernt eine Schicht aufweist, die das Verschweißen mit der Mantelallonge und der Rollenhülse ermöglicht, dadurch gekennzeichnet, daß auf der anderen Seite des Papierträgers eine Schicht eines synthetischen Polymers durch Extrusion aufgebracht ist, die dem Material eine Spannung verleiht, die ein nach innen Fallen des Flansches (von der Rolle aus gesehen) verhindert.
- Tageslichtverpackung nach Anspruch 1, dadurch gekennzeichnet, daß die Polymerschicht 20 bis 60 µm stark ist und aus Polyethylen besteht.
- Tageslichtverpackung nach Anspruch 1, dadurch gekennzeichnet, daß auf die Polymerschicht ein hitzebeständiger Lack aufgetragen ist.
