Abstract
Description
Die Erfindung betrifft Kantenschutzprofilstreifen aus Kunststoffmaterial und ein Herstellverfahren dafür. The invention relates to edge protection profile strips Plastic material and a manufacturing process therefor.
Es sind Kantenschutz-Winkelprofilstücke aus Kunststoffschaum- Material bekannt, die insbesondere als Unterlagen für Verpackungsgurte zum Schutz der Objektkante und des Gurtes verwendet werden. There are edge protection angle profile pieces made of plastic foam Known material, especially as documentation for Packing straps to protect the edge of the object and the belt be used.
Weiterhin sind Winkelprofilstreifen aus Pappe oder Kunststoff bekannt, die als Kantenbelag von auf Paletten gestapelter und vergurteter Ware oder zur Kantenauslegung in Kartons, Kisten oder dgl. genutzt werden. Furthermore, angular profile strips are made of cardboard or plastic known as the edge covering of stacked on pallets and taped goods or for laying edges in boxes, crates or Like. Be used.
Die Herstellung und Lagerung der Profilware ist verhältnismäßig aufwendig und platzbeanspruchend und deren Handhabung ist unpraktisch, da sie am Objekt keinen Halt hat, wenn die Gurte angelegt werden oder das Objekt in den Karton eingesetzt wird. Außerdem haben die massiven Kunststoff- oder Pappwinkel nur eine geringe Stoßdämpferwirkung. The manufacture and storage of the profiled goods is proportionate is complex and takes up space and their handling is impractical because it has no hold on the object when the straps created or the object is inserted into the box. In addition, the solid plastic or cardboard angles have only one low shock absorber effect.
Es ist Aufgabe der Erfindung, neuartige Kantenschutzstreifen zu schaffen, die eine höhere Stoßdämpfung aufweisen und leichter zu lagern sowie zu handhaben sind und ein einfaches Herstellverfahren dafür anzugeben. It is an object of the invention to provide novel edge protection strips create that have higher shock absorption and easier to store and handle and a simple manufacturing process to indicate for it.
Die Lösung besteht darin, daß das Kunststoff-Material ein Schaum- und Hohlkammermaterial ist, das geschlossene folienartige Deckschichten aufweist, die entlang mindestens einer geraden Linie unter weitgehender Verdrängung des inneren Schaumstoffmaterials - oder Hohlkammer - nutartig zusammengedrückt sind, so daß dort ein Kunststoffscharnier ausgebildet ist, und daß mindestens eine der Deckschichten mindestens einen Bereich aufweist, der mit einem Haftklebstoff beschichtet ist. The solution is that the plastic material is a foam and is hollow chamber material, the closed film-like Has cover layers along at least one straight line while largely displacing the inner foam material - or hollow chamber - are pressed together like a groove, so that there a plastic hinge is formed, and that at least one of the cover layers has at least one area which corresponds to a Pressure sensitive adhesive is coated.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben. Advantageous configurations are in the subclaims specified.
Die Dämpfung eines Schaumstoffmaterials läßt sich bekanntlich durch dessen Dicke und Dichte sowie die Materialauswahl bestimmen. Beispielsweise beträgt die Dicke 1-2 mm bei Schaumstoff, der Porenanteil 5-20% und die Dicke der Deckschichten 0,1-0,2 mm. Das mit Hohlkammern oder Kanälen extrudierte Material hat beispielsweise 0,1-0,2 mm dicke Deck- und Stützwände und eine Dicke von 1-2 mm. The damping of a foam material is known to be determine by its thickness and density as well as the choice of material. For example, the thickness is 1-2 mm for foam that Pores 5-20% and the thickness of the outer layers 0.1-0.2 mm. The material extruded with hollow chambers or channels for example 0.1-0.2 mm thick top and retaining walls and one Thickness of 1-2 mm.
Als Material eignen sich PVC, PE, PP, PU oder andere Kunststoffe, die jeweils so zu schäumen sind, daß sie geschlossene, folienartige Oberflächen aufweisen. Soweit thermoplastischer Kunststoff verwendet wird, läßt sich Recyclingmaterial einsetzen. Entsprechend der jeweiligen Anforderung empfiehlt es sich, etwa 5-20%, insbesondere 10%, Kautschukgranulat den geschredderten Thermoplasten zuzusetzen. Suitable materials are PVC, PE, PP, PU or other plastics, which are each to be foamed so that they are closed, have film-like surfaces. So far thermoplastic If plastic is used, recycling material can be used. According to the respective requirement, it is recommended to use approximately 5-20%, especially 10%, rubber granulate the shredded Add thermoplastics.
Die Nutungen entlang des Scharniers erfolgen etwa keilförmig mit einem Winkel von beispielsweise 60-90° divergierend. The grooves along the hinge are approximately wedge-shaped diverging at an angle of, for example, 60-90 °.
Die Deckschichten lassen sich je nach Bedarf in bekannter Weise glatt oder leicht strukturiert ausbilden, wodurch die Haftung am Objekt oder am Verpackungsmaterial geeignet zu gestalten ist. The cover layers can be made in a known manner as required train smooth or slightly structured, whereby the adhesion to Object or packaging material is to be designed appropriately.
Bevorzugt sind die mit Haftklebstoff beschichteten Bereiche entlang der Streifenränder und parallel zu dem Scharnier oder den Scharnieren ausgebildet, so daß die Streifen mit den Scharnieren über Objektkanten gelegt und mit den Haftklebstreifen daran befestigt werden können. Wird der Streifen in ein Behältnis eingesetzt, so wird das Scharnier in dessen Kantenbereich gedrückt und der Haftstreifen an der Behälterwand angedrückt und so fixiert. The areas coated with pressure sensitive adhesive are preferred along the strip edges and parallel to the hinge or the Hinges formed so that the strips with the hinges placed over the edges of objects and with the adhesive strips on them can be attached. The strip is placed in a container inserted, the hinge is pressed in its edge area and the adhesive strip pressed against the container wall and so fixed.
Die Klebstoffschicht ist vorteilhaft doppelseitig klebend und mit einer Schutzfolie einseitig bedeckt, die vor der Applikation entfernt wird. The adhesive layer is advantageously double-sided and adhesive a protective film that is covered on one side before application Will get removed.
Statt einer gesonderten Schutzfolie läßt sich eine Antihaftschicht bezüglich des Scharniers symmetrisch zum Klebstoffbereich auf die benachbarte Deckschicht aufbringen. Die beiden Bereiche lassen sich dann um das Scharnier zusammenfalten und gestapelt oder aufgerollt verpackt lagern. Durch Auffalten des Scharniers ist später die Haftklebstoffschicht freigelegt und einsatzbereit. Instead of a separate protective film, an anti-stick layer can be used with respect to the hinge symmetrical to the adhesive area on the Apply the adjacent top layer. Let the two areas then fold up around the hinge and stacked or store rolled up packed. By unfolding the hinge later the PSA layer is exposed and ready for use.
Das neuartige Herstellverfahren besteht darin, daß das streifenförmige Hohlkammer- oder Schaumstoffmaterial nach dem Extrudieren durch ein Paar von keilförmig profilierten, mit engem Spalt einander gegenüberstehenden drehbar gelagerten Scheiben hindurchgefördert wird, so daß in dem Spalt praktisch nur die Deckschichten des Kunststoffmaterials verbleiben und diese sich von dort aus nutartig erweiternd bis zur Originaldicke des Kunststoffmaterials erstrecken. Falls mit Kanälen extrudiertes Material durch die Nutscheiben gefördert wird, werden die Deckwandungen verformt und dadurch gelenkig zum Scharnier. The novel manufacturing process is that strip-shaped hollow chamber or foam material after the Extrude through a pair of wedge-shaped, narrow Gap opposite rotatably mounted discs is conveyed through, so that practically only the Cover layers of the plastic material remain and these themselves thence expanding from there to the original thickness of the Extend plastic material. If extruded with channels Material is conveyed through the grooved washers Top walls deformed and thus articulated to the hinge.
Der Durchlauf des Streifens zwischen den Scheiben erfolgt vorteilhaft dann, bzw. an der Stelle der Abförderung aus dem Extruder, wenn bzw. wo die äußeren Schichten bereits durch Abkühlung verfestigt sind und der Kern sich noch im erweichten Zustand befindet, so daß er sich ohne weiteres seitlich verdrängen läßt. The strip passes between the panes then advantageous, or at the point of removal from the Extruder if or where the outer layers are already through Cooling are solidified and the core is still softening Condition is so that it can easily displace laterally leaves.
Vorteilhafte Ausgestaltungen und Anwendungen sowie Herstellmittel zeigen Fig. 1-7. FIGS. 1-7 show advantageous configurations and applications as well as manufacturing means.

Fig. 6 und Fig. 7 zeigen Anwendungsbeispiele der Schutzstreifen. Fig. 6 and Fig. 7 show application examples of the protective strip.
Fig. 1 zeigt einen Rohling eines Kantenschutzstreifens, der aus einem geschäumten Kern 1 aus Kunststoff besteht, auf dem folienartige dünne Deckschichten 2, 3 beidseitig ausgebildet sind. Fig. 1 shows a blank of an edge protection strip, which consists of a foamed core 1 made of plastic, on the film-like thin cover layers 2 , 3 are formed on both sides.
Fig. 2 zeigt eine Vorrichtung zur Einbringung von Scharnierbereichen 4, 5 in den Schutzstreifen. Es sind jeweils mit Nutkanten 21, 23 eng gegenüberstehende keilförmig profilierte Nutscheiben 20, 22; 24, 25 auf in Lagern 28, 29 drehbar gelagerten Wellen 30, 31 angeordnet. Zwischen den Nutkanten 21, 23 passen nur die Deckschichten 2, 3 hindurch und das innere Material wird verdrängt. Fig. 2 shows a device for the introduction of hinge portions 4, 5 in the protective strip. There are each with groove edges 21 , 23 closely opposed wedge-shaped profiled washers 20 , 22 ; 24 , 25 arranged on shafts 30 , 31 rotatably mounted in bearings 28 , 29 . Only the cover layers 2 , 3 fit through between the groove edges 21 , 23 and the inner material is displaced.
Die Wellen 30, 31 sind als Gewindestangen ausgebildet, so daß die Nutscheiben 20, 22; 24, 25 mit gekonterten Muttern 26, 27 beliebig zu der Streifenbreitenerstreckung positioniert werden können sowie in unterschiedlicher Zahl dort aktiv aufeinander eingestellt werden können. Außerdem lassen sich mit einer scharfen Fase hergerichtete Schneidscheiben darauf anordnen, so daß in einem Arbeitsgang Scharniernuten und Streifen geschnitten werden können. The shafts 30 , 31 are designed as threaded rods, so that the grooved disks 20 , 22 ; 24 , 25 with locked nuts 26 , 27 can be positioned as desired to the strip width extension and can be actively adjusted to one another in different numbers there. In addition, cutting discs prepared with a sharp bevel can be arranged on it, so that hinge grooves and strips can be cut in one operation.
Fig. 3A zeigt einen mit zwei Nuten 4, 5 versehenen Schutzstreifen, dessen Mittelbereichsbreite auf die Dicke eines Objektes oder Objektstapels abgestimmt ist, das randseitig abgedeckt umschlossen werden soll. FIG. 3A shows a protective strip provided with two grooves 4 , 5 , the width of the central region of which is matched to the thickness of an object or stack of objects which is to be enclosed and covered at the edges.
Die umzuschlagenden Seitenstreifenbereiche 6, 7 sind, wie Fig. 3B zeigt, mit Klebstoffschichten 8 beschichtet, die mit abziehbaren Schutzfolien 9 abgedeckt sind. The side strip regions 6 , 7 to be folded over are coated with adhesive layers 8 , as shown in FIG. 3B, which are covered with removable protective films 9 .
Fig. 3C zeigt den Streifen mit entlang der Scharniere 4, 5 eingeschlagenen Seitenbereichen, und Fig. 3D zeigt solche Streifen gestapelt und mit einer Hülle 10 verpackt. Statt der Schutzfolie 9 kann auch eine Antihaftschicht auf der Deckschicht 2 des Mittelbereiches aufgebracht sein. FIG. 3C shows the strip with side areas folded in along the hinges 4 , 5 , and FIG. 3D shows such strips stacked and packed with a sleeve 10 . Instead of the protective film 9 , an anti-adhesive layer can also be applied to the cover layer 2 of the central region.
Fig. 4 zeigt einen mit Kanälen 14 durchzogenen Streifen, der aus folienartigen Deckflächen 2, 3 und dünnen Abstandsstegen 13 besteht. Die Kanäle 14 haben eine flache Rechteckform. Die Randstreifenbereiche 6, 7 sind, wie im anderen Beispiel, mit Haftklebstoff 8 belegt und parallel dazu erstrecken sich die eingedrückten Scharnierbereiche 4, 5. Fig. 4 shows a strip with channels 14 , which consists of film-like cover surfaces 2 , 3 and thin spacers 13 . The channels 14 have a flat rectangular shape. As in the other example, the edge strip regions 6 , 7 are covered with pressure-sensitive adhesive 8 and the pressed-in hinge regions 4 , 5 extend parallel to this.
Fig. 5 zeigt einen vergrößerten Ausschnitt des Hohlkammermaterials, dessen Deckwandungen 2, 3 entlang eines Kanals verformt sind, so daß sie ein Scharnier bilden. Statt des rechteckigen Kanalverschnitts sind je nach Anwendungsfall auch dreieckige oder trapezförmige Kanalquerschnitte einzubringen, indem die Stützwände wechselweise geneigt gestellt sind. Dies erbringt eine erhöhte Knickstabilität insbesondere gegen eine Querkomponente einer einwirkenden Kraft. Fig. 5 shows an enlarged section of the hollow chamber material, the top walls 2 , 3 are deformed along a channel so that they form a hinge. Instead of the rectangular duct cut, depending on the application, triangular or trapezoidal duct cross-sections should also be used, in that the supporting walls are alternately inclined. This results in increased kink stability, in particular against a transverse component of an acting force.
Fig. 6 zeigt ein Beispiel einer Anwendung, bei dem Kantenschutzstreifen mit einem Scharnier 4 und einem Klebstoffstreifen 8 in Kartoninnenkanten eingeklebt sind. Da die genuteten Streifen eine leichte Tendenz zum Abflachen haben, genügt es, sie an einer Seite zum Haften zu bringen. Fig. 6 shows an example of an application in which edge protection strips with a hinge 4 and an adhesive strip 8 are glued into the inner edges of the cardboard. Since the grooved strips have a slight tendency to flatten, it is sufficient to make them stick to one side.
Ein weiteres Beispiel zeigt Fig. 7, wo kurze Winkelstreifenabschnitte 40 über Kanten eines Objektstapels und einer Palette angeheftet sind, über welche Gurte gespannt worden sind. Die Streifen lassen sich jederzeit leicht abnehmen und wiederverwenden oder wie das verbleibende Verpackungsmaterial sortenrein entsorgen. A further example is shown in FIG. 7, where short angle strip sections 40 are attached over edges of an object stack and a pallet, over which belts have been tensioned. The strips can be easily removed and reused at any time or, like the remaining packaging material, disposed of separately.
