- blankets or covers made of plastic material Use are each provided as intermediate layers or as a covering and consist in particular of a latticework made by extrusion, which consists of two crossed arrangements of transversely spaced strands is formed, the strands at the intersection of the two arrangements run perpendicular or at an angle to the strands of the other arrangement.
- the strands come to lie on two levels, such that in each level the strands are aligned parallel to each other.
- a tubular structure is known that is used for the production of bags or sacks for packaging purposes.
- the tubular structure has closed areas and areas with a network structure. Both Areas are already produced during extrusion.
- FR-A-1 210 534 is about woven tapes or fabrics after weaving treated with pressure and heat to change their structure. It can be too a fusion of the threads and optionally a layer of compact structure without the addition of additional material. This leaves woven ribbons and fabrics in the relatively small spaces easily form between the threads.
- the invention has for its object to provide a blanket or envelope whose Network structure is designed so that it is essentially a continuous one Lets form surface. Furthermore, the object of the invention is to provide a corresponding one Creating procedures.
- a blanket or cover for solving this problem has the features of claim 1 on.
- the surface is therefore an integral part of the network structure, in this Area the original network structure was removed and instead an essentially continuous area is available.
- Identification surface Information, information or the like can be placed on the surface for example to identify or explain the protective cover covered parts are applied. It is possible to apply a sticker that Printing the surface, embossing it, inserting characters into the surface (also as a recess), etc.
- the surface can also be used as a base or serve to hold objects. Connecting additional Information carrier with the protective blanket, for example attaching a trailer with appropriate information, is unnecessary.
- a method for solving the problem has the measures of claim 8.
- By the deformation of the network structure creates at least one surface. This area will formed by the original network structure in the area of the or each surface canceled and instead a substantially continuous surface is formed.
- the material forming the network structure is preferably so warmed up or compressed until a continuous Surface is formed.
- continuous area does not mean that a completely smooth and homogeneous Surface structure must arise. It is important that the formed area as a basis or documents for information, characters or to be applied or to be introduced Objects are sufficient. Unless it is the purpose of the area corresponds, a sticker on it should be strong enough can be liable. This can also be the case if the in the Breakthroughs in the network structure are not complete are closed.
- the molded surface preferably has a clear lower height or strength than the rest of the network structure.
- the latter has a height corresponding to the two superimposed layers. In contrast is the area due to the fact that it is pushed into the gaps in the network structure Material much thinner.
- the surface can be flat or deformed be or have deformations.
- the invention is also applicable to those formed from a network structure Cases or bags, for example to protect rotationally symmetrical or rod-shaped objects, such as Waves, cones or the like.

Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Herstellung einer Decke oder einer
Hülle gemäß dem Oberbegriff des Anspruchs 8.The invention relates to a blanket or envelope made of a plastic material according to the
Preamble of
Zum Schutz empfindlicher Bauteile, die beispielsweise auf Paletten oder in Behältern transportiert werden, finden vielfach Decken oder Hüllen aus Kunststoffmaterial Verwendung. Diese sind jeweils als Zwischenlagen oder als Umhüllung vorgesehen und bestehen insbesondere aus einem durch Extrusion hergestellten Gitterwerk, das aus zwei gekreuzten Anordnungen von transversal im Abstand zueinander vorliegenden Strängen ausgebildet ist, wobei die Stränge an den Kreuzungspunkten der beiden Anordnungen senkrecht oder schräg zu den Strängen der anderen Anordnung verlaufen. Üblicherweise kommen die Stränge in zwei Ebenen zu liegen, derart, daß in jeder Ebene die Stränge zueinander parallel ausgerichtet sind.To protect sensitive components, for example on pallets or in containers often find blankets or covers made of plastic material Use. These are each provided as intermediate layers or as a covering and consist in particular of a latticework made by extrusion, which consists of two crossed arrangements of transversely spaced strands is formed, the strands at the intersection of the two arrangements run perpendicular or at an angle to the strands of the other arrangement. Usually the strands come to lie on two levels, such that in each level the strands are aligned parallel to each other.
So werden Zulieferteile für die Automobilindustrie in Behältern lagenweise transportiert, wobei zwischen den einzelnen Lagen jeweils Schutzdecken aus Kunststoffmaterial mit Netzstruktur vorgesehen sind. Zur Identifizierung der abgedeckten Teile oder der Eigenschaften der Decke bzw. Hülle sind auf der Decke leicht zu fixierende und gut lesbare Angaben von Vorteil.Supplied parts for the automotive industry are transported in layers in containers, with protective blankets made of plastic material between the individual layers Network structure are provided. To identify the covered parts or the The properties of the blanket or cover are easy to fix and good on the blanket Readable information is an advantage.
Aus der FR-A-2 584 651 ist bekannt, Verpackungsbeutel aus einer extrudierten Kunststoffhülle zu bilden, deren Wandung wenigstens teilweise perforiert ist. Es wird dazu ein Kunststoffschlauch mit einer ursprünglich geschlossenen Wandung extrudiert. Während der Extrusion wird die geschlossene Wandung teilweise mit Perforationen versehen.From FR-A-2 584 651 it is known packaging bags made of an extruded plastic casing form, the wall of which is at least partially perforated. It becomes one Extruded plastic tubing with an originally closed wall. While During the extrusion, the closed wall is partially perforated.
Aus der FR-A-2 572 991 ist ein schlauchförmiges Gebilde bekannt, das zur Herstellung von Beuteln oder Säcken für Verpackungszwecke dient. Das schlauchförmige Gebilde weist geschlossenflächige Bereiche und Bereiche mit einer Netzstruktur auf. Beide Bereiche werden bereits bei der Extrusion hergestellt.From FR-A-2 572 991 a tubular structure is known that is used for the production of bags or sacks for packaging purposes. The tubular structure has closed areas and areas with a network structure. Both Areas are already produced during extrusion.
Bei der FR-A-1 210 534 geht es darum, gewebte Bänder oder Stoffe nach dem Weben durch Druck und Hitze zu behandeln, um ihre Struktur zu verändern. Dabei kann es zu einem Verschmelzen der Fäden kommen und gegebenenfalls eine Schicht von kompakter Struktur ohne die Hinzufügung zusätzlichen Materials entstehen. Dieses lässt sich aus gewebten Bändern und Stoffen in den verhältnismäßig kleinen Zwischenräumen zwischen den Fäden problemlos bilden.FR-A-1 210 534 is about woven tapes or fabrics after weaving treated with pressure and heat to change their structure. It can be too a fusion of the threads and optionally a layer of compact structure without the addition of additional material. This leaves woven ribbons and fabrics in the relatively small spaces easily form between the threads.
Bei der aus der FR-A-2 584 651 und der FR-A-2 572 991 bekannten Extrusion von flächigen Bereichen mit dazwischen liegenden netzförmigen oder perforierten Bereichen müssen die Flächen in Längsrichtung des extrudierten Gebildes durchgehen.At the out FR-A-2 584 651 and FR-A-2 572 991 known extrusion of flat Areas with mesh-like or perforated areas in between go through the surfaces in the longitudinal direction of the extruded structure.
Der Erfindung liegt die Aufgabe zugrunde, eine Decke oder Hülle zu schaffen, deren Netzstruktur so ausgebildet ist, dass sich daraus eine im Wesentlichen durchgehende Fläche bilden lässt. Des Weiteren besteht die Aufgabe der Erfindung darin, ein entsprechendes Verfahren zu schaffen. The invention has for its object to provide a blanket or envelope whose Network structure is designed so that it is essentially a continuous one Lets form surface. Furthermore, the object of the invention is to provide a corresponding one Creating procedures.
Eine Decke oder Hülle zur Lösung dieser Aufgabe weist die Merkmale des Anspruchs 1
auf. Die Fläche ist demnach integraler Bestandteil der Netzstruktur, indem in diesem
Bereich die ursprüngliche Netzstruktur aufgehoben und statt dessen eine im wesentlichen
durchgehende Fläche vorhanden ist. Auf diese Weise entsteht wenigstens eine
Kennzeichnungsfläche. Auf die Fläche können Informationen, Angaben oder dergleichen
beispielsweise zur Identifizierung oder Erläuterung der durch die Schutzdecke
abgedeckten Teile aufgebracht werden. Möglich ist das Aufbringen eines Aufklebers, das
Bedrucken der Fläche, das Prägen derselben, das Einbringen von Zeichen in die Fläche
(auch als Ausnehmung derselben) usw. Daneben kann die Fläche auch als Unterlage
oder zur Aufnahme von Gegenständen dienen. Das Verbinden zusätzlicher
Informationsträger mit der Schutzdecke, beispielsweise das Anbringen eines Anhängers
mit entsprechenden Informationen, erübrigt sich.A blanket or cover for solving this problem has the features of
Ein Verfahren zur Lösung der Aufgabe weist die Maßnahmen des Anspruchs 8 auf. Durch die Verformung der Netzstruktur entsteht mindestens eine Fläche. Diese Fläche wird dadurch gebildet, daß die ursprüngliche Netzstruktur im Bereich der oder jeder Fläche aufgehoben und statt dessen eine im wesentlichen durchgehende Fläche gebildet wird. A method for solving the problem has the measures of claim 8. By the deformation of the network structure creates at least one surface. This area will formed by the original network structure in the area of the or each surface canceled and instead a substantially continuous surface is formed.
Vorzugsweise wird der die Netzstruktur bildende Werkstoff so weit erwärmt bzw. zusammengepresst, bis eine durchgehende Fläche gebildet ist. Die Definition "durchgehende Fläche" bedeutet dabei nicht, daß eine völlig glatte und homogene Oberflächenstruktur entstehen muß. Wichtig ist, daß die gebildete Fläche als Grundlage oder Unterlagen für aufzubringende oder einzubringende Informationen, Zeichen oder Gegenstände ausreicht. Sofern es dem Zweck der Fläche entspricht, sollte ein Aufkleber auf ihr ausreichend stark haften können. Dies kann auch der Fall sein, wenn die in der Netzstruktur vorhandenen Durchbrüche nicht vollständig geschlossen sind.The material forming the network structure is preferably so warmed up or compressed until a continuous Surface is formed. The definition "continuous area" does not mean that a completely smooth and homogeneous Surface structure must arise. It is important that the formed area as a basis or documents for information, characters or to be applied or to be introduced Objects are sufficient. Unless it is the purpose of the area corresponds, a sticker on it should be strong enough can be liable. This can also be the case if the in the Breakthroughs in the network structure are not complete are closed.
Die eingeformte Fläche weist vorzugsweise eine deutlich geringere Höhe bzw. Stärke auf als die Netzstruktur im übrigen. Letztere weist eine Höhe entsprechend den beiden übereinanderliegenden Lagen auf. Demgegenüber ist die Fläche aufgrund des in die Zwischenräume der Netzstruktur verdrängten Materials wesentlich dünner. Die Fläche kann eben oder verformt sein oder Verformungen aufweisen.The molded surface preferably has a clear lower height or strength than the rest of the network structure. The latter has a height corresponding to the two superimposed layers. In contrast is the area due to the fact that it is pushed into the gaps in the network structure Material much thinner. The surface can be flat or deformed be or have deformations.
Die Erfindung ist auch anwendbar für aus einer Netzstruktur gebildete Hüllen oder Taschen, beispielsweise zum Schutz von rotationssymmetrischen oder stabförmigen Gegenständen, wie Wellen, Zapfen oder dergleichen. Auch können derartige Hüllen auf einem als Unterlage dienenden Zapfen zur Bildung der Kennzeichenfläche mit einem entsprechende Konturen aufweisenden Stempel beaufschlagt werden.The invention is also applicable to those formed from a network structure Cases or bags, for example to protect rotationally symmetrical or rod-shaped objects, such as Waves, cones or the like. Such covers can also on a pin that serves as a base to form the License plate area with a corresponding contours Stamps are applied.

Eine etwa rechteckige Decke 10 dient der Abdeckung und dem
Schutz von in Behältern oder auf Paletten zu transportierenden
mechanischen Bauteilen. Beispielsweise wird die Decke 10 auf
eine Lage von Bauteilen in einem Behälter abgelegt, bevor eine
weitere Lage von Bauteilen eingefüllt wird.An approximately
Hergestellt ist die Decke 10 vorzugsweise aus thermoplastischem
Kunststoff und zwar aus zwei im Bereich von Kreuzungspunkten 11
miteinander verbundenen Lagen 12, 13, jeweils bestehend aus
zueinander parallelen Kunststoffsträngen 14, 15. Diese sind
durch Extrusion gebildet und haften im Bereich der
Kreuzungspunkte 11 an den Strängen der jeweils anderen Lage.The
In die Decke 10 ist eine Kennzeichnungsfläche 16 bzw. eine als
Unterlage oder Auflage vorgesehene Fläche eingearbeitet. Diese
ist im vorliegenden Fall nahezu kreisrund, kann aber eine
beliebige Form aufweisen.In the
Gebildet ist die Kennzeichnungsfläche 16 durch einen beheizten
Rundstempel 17, der mit leichtem Druck auf der Decke 10 solange
positioniert wird, bis die durch die Kunststoffstränge 14, 15
gebildete Netzstruktur weitgehend aufgelöst und die genannte
Kennzeichnungsfläche 16 entstanden ist.The
Durch Druck des Stempels 17 auf die beiden Lagen 12, 13 erfolgt
ein Aufheben der Netzstruktur und eine Verdrängung des Materials
der Kunststoffstränge 14, 15 in die im übrigen vorhandenen
Zwischenräume 18. Auf diese Weise entsteht die durchgehende
Kennzeichnungsfläche 16.By pressing the
Der Stempel 17 arbeitet mit einer Unterlage 19 als Gegenwerkzeug
zusammen. Diese ist zum Stempel korrespondierend
ausgebildet, ohne Vertiefungen, Ausnehmungen oder dergleichen.
Dadurch schließt eine Unterseite 20 des entstehenden
verdichteten Abschnitts 21 der Kennzeichnungsfläche 16 etwa
bündig mit der unteren Lage 13 ab. Im Gegensatz dazu ist eine
Oberseite 22 des Abschnitts 21 gegenüber der oberen Lage 12
einwärts versetzt. Je nach Maschenweite der Netzstruktur kann
sich auch ein Absatz 23 in Richtung auf die Unterseite 20 und
als umlaufender Rand des verdichteten Abschnitts 21 einstellen.The
Eine Stempelfläche 24 ist vorzugsweise eben ausgebildet, ebenso
die entstehende Fläche 16. Andere Formen, etwa Ausnehmungen,
Vertiefungen und Vorsprünge sind möglich.A
Wärme und Druck des Stempels sind abhängig vom Material der
Decke 10 und von der gewünschten Dichte bzw. dem gewünschten
Aufbau der Kennzeichnungsfläche 16. Ein Thermoplast kann auf
einfache Weise bzw. in kurzer Zeit angeschmolzen und aus einer
Netzstruktur zu einer durchgehenden Kennzeichnungsfläche umgeformt
werden. Ein besonderer Vorteil dieses Verfahrens liegt
darin, daß kein Material hinzugegeben werden muß. Es erfolgt
lediglich eine Umformung des vorhandenen Materials.The heat and pressure of the stamp depend on the material of the
Die Kennzeichnungsfläche 16 wird in einem gesonderten Arbeitsgang
oder während der Umformung der Netzstruktur mit einer
Beschriftung versehen, beispielsweise mit Informationen über
die durch die Decke 10 zu schützenden Bauteile. Der Stempel 17
kann beispielsweise die gewünschten Angaben während des
Umformvorgangs in die Kennzeichnungsfläche 16 einprägen. In den
Fig. 1 und 2 ist als Anwendung die Angabe einer
Identifikationsnummer gezeigt.The marking
Die Beschriftung erfolgt vorzugsweise auf der einwärts versetzten
Oberseite 22. Dadurch besteht ein zusätzlicher Schutz gegen
Zerstörung, etwa durch großflächige und schwere aufgelegte weitere
Bauteile.The labeling is preferably on the inward offset
Auf die Kennzeichnungsfläche 16 bzw. die Oberseite 22 oder Unterseite
20 können auch nachträglich Informationen aufgebracht
werden, etwa durch Prägen, Bedrucken oder Bekleben. In jedem
Falle ist die Beschriftung einfacher als bei Vorhandensein nur
der reinen Netzstruktur.On the marking
In einer nicht gezeigten Ausführungsform ist an Stelle einer
Decke 10 eine rohrförmige, mantelförmige oder taschenförmige
Hülle vorgesehen. Auch diese kann durch Verwendung geeigneter
Werkzeuge mit einer Kennzeichnungsfläche versehen werden. So
kann eine Hülle zum Schutz einer Welle durch Einbringen eines
Dorns und einen außen angreifenden Stempel in nahezu derselben
Weise zur Bildung einer Kennzeichnungsfläche umgeformt werden
wie die Decke 10.In one embodiment, not shown, instead of one
