Abstract

An L-shaped extruded edge-protector section for the strapping of articles, stacks or the like, has along the inner or outer surfaces of the respective flanges, respective adhesive strips while the opposite surfaces having longitudinal recesses so that when the edge-protectors are stacked, the adhesive strips are received with clearance in the recesses of adjacent edge-protectors. The edge-protectors when stacked thus do not adhere to one another even though masking strips are not provided for the adhesive strips.

Description

Die Erfindung betrifft einen Kantenschutzprofilabschnitt zur Verwendung in Verbindung mit Umreifungsmaßnahmen von Warenstapeln, Paketen, u. dgl., - mit einem im wesentlichen L-förmigen Profilquerschnitt und an den Innenflächen vorgesehenen Selbstkleberlängsstreifen.The invention relates to an edge protection profile section for use in connection with strapping measures of stacks of goods, packages, and. Like. - With a substantially L-shaped profile cross section and longitudinal adhesive strips provided on the inner surfaces.

Bekannte Kantenschutzprofilabschnitte der genannten Art (EP-A1-0 089 533) bestehen regelmäßig aus einem um seine mittlere Längsachse gebogenen Papplagenlaminat. Das ist insofern nicht ganz befriedigend, als der Kantenschutzprofilabschnitt an seiner mittleren Innenlängskante gleichsam gerundet ist, so daß beim äußeren Anlegen eines Umreifungsbandes scharfkantige harte Packstücke, wie z.B. Möbel, trotz Kantenschutzfunktion noch beschädigt werden können. Das kann durch eine rinnenförmige Längsausnehmung an der mittleren Innenlängskante vermieden werden (DE-A1-28 05 698). Unbefriedigend ist auch, daß das Umreifungsband im Querschnitt des Profilabschnittes gesehen an der gesamten Außenfläche des Kantenschutzprofilabschnittes anliegt, wodurch im Zuge der Umreifung oftmals eine einwandfreie Spannung des Umreifungsbandes nicht erreicht wird. Die Selbstkleberlängsstreifen an den Innenflächen dienen der kurzzeitigen Fixierung des Kantenschutzprofilabschnittes im Zuge der Umreifungsmaßnahmen. Da die Kantenschutzprofilabschnitte regelmäßig in Stapeln angeliefert werden, besteht natürlich die Gefahr des Gegeneinanderverklebens des Papplagenlaminates in der Stapeleinheit und ist das problemlose Entfernen des einzelnen Kantenschutzprofilabschnittes erschwert, weshalb im Stapel die einzelnen Kantenschutzprofilabschnitte mindestens an der Berührungsseite mit Silikonpapier ummantelt sind. Das ist aufwendig. Außerdem verbraucht sich durch diese nicht beabsichtigte Verklebung während des Stapelns die adhäsive Eigenschaft an der Oberfläche des Klebemittels.Known edge protection profile sections of the type mentioned (EP-A1-0 089 533) regularly consist of a cardboard layer laminate bent about its central longitudinal axis. This is not entirely satisfactory in that the Edge protection profile section is, as it were, rounded on its central inner longitudinal edge, so that when a strapping is put on the outside, hard-edged hard packages, such as furniture, can still be damaged despite the edge protection function. This can be avoided by a groove-shaped longitudinal recess on the central inner longitudinal edge (DE-A1-28 05 698). It is also unsatisfactory that the strapping, seen in cross-section of the profile section, rests against the entire outer surface of the edge protection profile section, as a result of which a correct tensioning of the strapping is often not achieved in the course of the strapping. The self-adhesive longitudinal strips on the inner surfaces serve to temporarily fix the edge protection profile section in the course of the strapping measures. Since the edge protection profile sections are regularly delivered in stacks, there is of course the risk of the cardboard layer laminate sticking to one another in the stacking unit and the problem-free removal of the individual edge protection profile sections is made difficult, which is why the individual edge protection profile sections in the stack are covered with silicone paper at least on the contact side. It is expensive. In addition, this unintended bonding consumes the adhesive property on the surface of the adhesive during stacking.

Der Erfindung liegt die Aufgabe zugrunde, den Kantenschutzprofilabschnitt der eingangs genannten Art so auszubilden, daß im Zuge der Umreifungsmaßnahmen mit dem Umreifungsband in manipulationstechnischer Hinsicht keinerlei Probleme bzw. Besonderheiten bestehen.The invention has for its object to design the edge protection profile section of the type mentioned that in the course the strapping measures with the strapping have no problems or special features in terms of manipulation.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß der Kantenschutzprofilabschnitt aus einer zumindest teilweise aus thermoplastischem Kunststoff bestehenden Masse extrudiert ist und zwischen Längskanten mit jeweils einer durchlaufenden Längseinbuchtung versehen ist, in der der zugeordnete Selbstkleberlängsstreifen eines im Stapel vorgelagerten Profilabschnittes ohne Berührung der Einbuchtungsoberfläche liegt. Bei dem erfindungsgemäßen Kantenschutzprofilabschnitt können die Längseinbuchtungen auf der Außenseite der Profilflansche, die Selbstkleberlängsstreifen auf deren Innenseite angeordnet sein. Man kann die Anordnung aber auch so treffen, daß die Längseinbuchtungen auf der Innenseite der Profilflansche, die Selbstkleberlängsstreifen auf deren Außenseite angeordnet sind.The solution to this problem according to the invention is that the edge protection profile section is extruded from an at least partially made of thermoplastic material and is provided between longitudinal edges with a continuous longitudinal indentation in which the associated self-adhesive longitudinal strip of an upstream profile section lies without touching the indentation surface. In the edge protection profile section according to the invention, the longitudinal indentations can be arranged on the outside of the profile flanges and the self-adhesive longitudinal strips on the inside thereof. However, the arrangement can also be such that the longitudinal indentations are arranged on the inside of the profile flanges and the self-adhesive longitudinal strips are arranged on the outside thereof.

Die Erfindung geht von der Überlegung aus, daß der Einsatz von Silikonpapierummantelungen bzw. -zwischenlagen im Stapel entfallen kann, wenn das Profil mit entsprechenden äußeren Längseinbuchtungen hergestellt wird. Das ist bei einer Herstellung des Kantenschutzprofilabschnittes aus Papplagenlaminat nicht möglich. Vielmehr muß der Kantenschutzprofilabschnitt hierfür durch Extrusion hergestellt werden, die Selbstkleberlängsstreifen werden vorzugsweise durch Koextrusion erzeugt. Das kann ohne weiteres aus thermoplastischem Kunststoff allein, z.B. einem Abfallprodukt in Form von Polyäthylen geschehen, es besteht aber ohne weiteres auch die Möglichkeit, mit einem Papier/Kunststoffabfallgemisch zu arbeiten. Die äßeren Längseinbuchtungen haben zudem den Vorteil, daß die Anlagefläche für das Umreifungsband ganz beachtlich verringert wird, so daß es zu Schlaffheiten im angelegten Umreifungsband nicht mehr kommen kann. - Nach bevorzugter Ausführungsform ist der erfindungsgemäße Kantenschutzprofilabschnitt an seiner mittleren Innenlängskante mit einer rinnenförmigen Längsausnehmung versehen. Hierdurch wird eine Verformung der Profilflansche ermöglicht und sichergestellt, daß sie im Stapel genau die vorgegebene Position annehmen, bei der die Selbstkleberlängsstreifen sich über den Einbuchtungen befinden. Auch ist sichergestellt, daß spitze empfindliche Kanten, in deren Bereich der Kantenschutzprofilabschnitt aufgesetzt wird, nicht beschädigt werden können, da sie innerhalb der Längsausnehmungen zu liegen kommen. Auch das setzt eine Herstellung des Kantenschutzprofilabschnittes durch Extrusion voraus.The invention is based on the consideration that the use of silicone paper sheathing or intermediate layers in the stack can be omitted if the profile is produced with corresponding outer longitudinal indentations. This is not possible when the edge protection profile section is made from cardboard layer laminate. Rather, the edge protection profile section must be produced by extrusion for this purpose, the self-adhesive longitudinal strips are preferably produced by coextrusion. This can easily be done from thermoplastic material alone, for example a waste product in the form of polyethylene, but there is also the possibility of using one Paper / plastic waste mix to work. The outer longitudinal indentations also have the advantage that the contact surface for the strapping is reduced considerably, so that slackness in the strapping applied can no longer occur. - According to a preferred embodiment, the edge protection profile section according to the invention is provided on its central inner longitudinal edge with a channel-shaped longitudinal recess. This enables deformation of the profile flanges and ensures that they assume exactly the predetermined position in the stack in which the self-adhesive longitudinal strips are located above the indentations. It is also ensured that sharp, sensitive edges, in the area of which the edge protection profile section is placed, cannot be damaged, since they come to lie within the longitudinal recesses. This also requires the edge protection profile section to be produced by extrusion.

  • Fig. 1 shows a stack of edge protection profile sections for use in connection with strapping measures of stacks of goods, packages and. Like. And
  • 2 shows an edge protection profile section attached to a stack of goods, package or the like with a strapping applied.

Wie aus den Figuren ohne weiteres ersichtlich ist, wird der Kantenschutzprofilabschnitt 1 in Verbindung mit Umreifungsmaßnahmen von Warenstapeln, Paketen u. dgl. verwendet. Er weist einen im wesentlichen L-förmigen profilquerschnitt auf und ist an den Innenflächen mit Selbstkleberlängsstreifen 2 versehen, mit deren Hilfe der Kantenschutzprofilabschnitt 1 an einem Packstück, wie z.B. einem Möbel stück zufolge seiner Klebrigkeit haftet.As is readily apparent from the figures, the edge protection profile section 1 is in connection with strapping measures of stacks of goods, packages and. Like. Used. It has a substantially L-shaped profile cross section and is provided on the inner surfaces with self-adhesive longitudinal strips 2, with the aid of which the edge protection profile section 1 adheres to a package, such as a piece of furniture, due to its stickiness.

Das Kantenschutzprofil ist aus einer Masse extrudiert, die zumindest teilweise aus thermoplastischem Kunststoff, insbes. Polyäthylen, besteht. Besonders geeignet sind Abfälle aus Papier und thermoplastischem Kunststoff in Form von kunststoffkaschiertem Papier. Zwischen den Außenlängskanten ist jeweils eine durchlaufende Längseinbuchtung 3 vorgesehen, in der der zugeordnete koextrudierte Selbstkleberlängsstreifen 2 eines im Stapel vorgelagerten Profilabschnittes 1 ohne Berührung der Einbuchtungsoberfläche liegt (vgl. Fig. 1). Im übrigen entnimmt man Fig. 2, daß der Kantenschutzprofilabschnitt 1 an seiner mittleren Innenlängskante mit einer rinnenförmigen Längsausnehmung 4 versehen ist, die Beschädigungen empfindlicher Kanten von Packstücken mit Sicherheit ausschließt.The edge protection profile is extruded from a mass which at least partially consists of thermoplastic, in particular polyethylene. Waste made of paper and thermoplastic in the form of plastic-coated paper is particularly suitable. A continuous longitudinal indentation 3 is provided between each of the outer longitudinal edges, in which the associated coextruded self-adhesive longitudinal strip 2 of a profile section 1 located in the stack lies without touching the indentation surface (cf. FIG. 1). 2 that the edge protection profile section 1 is provided on its central inner longitudinal edge with a trough-shaped longitudinal recess 4, which excludes damage to sensitive edges of packages with certainty.
