Definitions
- the invention is based on a cover film with the features of the preamble of claim 1.
- a cover film is known from US-A-4,263,347.
- Another cover film known from practice consists of a band-shaped film web endlessly wound on a roll, which is provided with an adhesive strip along one edge.
- the adhesive is applied directly to the film web. In this way, reinforcement of the film web in the area of the adhesive strip is to be avoided as far as possible, since reinforcements have the consequence when winding the film web into a roll that the winding or the roll becomes conical or conical.
- the wrap is not firm and can fold, which then leads to considerable problems in further handling.
- the roll in which the cover film is supplied has a length corresponding to the width of the film web.
- a plastic film for covering motor vehicle seats is known from EP-A-01 87 982. This film only serves as a loose cover and has no precautions with which the film can be attached to the motor vehicle seat.
- the film which is initially flat, is wrapped in different widths on its two longitudinal edges. Then the lengthwise pre-folded cover film is folded together in the middle between the two folding edges that arise to form a kind of half-tube.
- the resulting film tape is therefore thicker on one edge than on the other edge due to the different number of folded edges.
- the cover film is also folded leporello-like inwards in the area of the folded edge that creates the half-tube, so that the same number of layers is superimposed on both film edges before the film web is wound up into a roll.
- the use of the reinforcement strip in the area of the adhesive prevents the film web from having different thicknesses at its two edges which arise after folding. If, for example, the film web is wrapped only once in the longitudinal direction, the reinforcement strip has the thickness of the film web. As a result, the tape obtained after folding is just as thick in the area of the adhesive as the edge formed by the fold. Winding up to the roll will result in an exactly cylindrical roll. After being rolled up into a roll, both edges are pressed tightly against one another, which prevents dirt from penetrating and also makes the edge less sensitive to damage.
- the cover film becomes particularly user-friendly if the reinforcement strip is located between the adhesive with which the film is glued to the base and the film web. When using the film, no separate strip has to be peeled off the adhesive. On the other hand, in the wound state, the adhesive is protected from drying out by the subsequent winding layer, because of the same thickness of the Foil on both edges, even in the area of the adhesive, the wrapping layers are firmly on top of each other.
- the film web can, for example, be folded like a leporello, the next fold being in the vicinity of the adhesive strip.
- the folding is carried out in such a way that after folding in the area of both edges of the tape obtained, the same material thickness is found and that in any case there is no thicker between these edges of the tape.
- the figure does not show a covering film 1 to scale to protect surfaces which must not be contaminated when processing adjacent surfaces.
- the cover film 1 consists of an elongated band-shaped film web 2 which is delimited by two straight side edges 3, 4 running parallel and at a distance from one another. Between these two side edges 3, 4, the film web 2 is folded like a leporello, whereby two continuous folding edges 5, 6 are formed in the longitudinal direction. As a result, the width of the film web 2 is divided into a total of three areas 7, 8 and 9, the areas 8 and 9 being congruent and the area 7 near the side edge 3 projecting beyond the areas 8, 9 with a strip-shaped area 11.
- the strip-shaped area 11 carries on the side on which the areas 8 and 9 are located after the fan fold, a reinforcing strip 12, the width of which is slightly less than the width of the strip 11 and which extends over the entire length of the film web 2.
- the reinforcement strip 12 ends laterally at the side edge 3, i.e. neither the reinforcement strip 12 projects beyond the film web 2 nor does the film web 2 project beyond the reinforcement strip 12.
- the reinforcement strip 12 is permanently connected to the relevant side of the film web 2 by gluing or welding. It carries on its side facing away from the film web 2 an adhesive layer 13 which adheres more strongly to the reinforcement strip 12 than to the documents to which the cover film 1 is to be glued. The adhesive layer 13 completely covers that of the film web 2 technological side of the reinforcement strip 12 and runs continuously over the entire length of the reinforcement strip 12 and thus the film web 2.
- the thickness of the adhesive layer 13 is negligibly thin.
- the reinforcement strip 12 has a thickness or thickness which corresponds to the thickness of the two superimposed regions 8 and 9, i.e. the thickness of the reinforcement strip 12 is equal to n times the thickness of the film web 2, where n is the number of folds along which the film web 2 is wrapped or folded.
- the film web is folded along the two folded edges 5, 6, which run parallel to one another at a distance from one another, i.e. folded twice, i.e. the reinforcement strip 12 has twice the thickness of the film web 2.
- the cover sheet 1 which is stretched out flat and, as illustrated, folded like a leporello, is just as thick in the region of the side edge 3 as in the region of the side edge 4, which is located directly above the folded edge 5.
- the side edge 4 and the folding edge 5 are congruent, so that in turn neither the side edge 4 protrudes beyond the folding edge 5 nor vice versa the folding edge 5 beyond the side edge 4.
- the cover sheet 1 Due to the design of the cover sheet 1 shown, it can be wound into the schematically illustrated cylindrical roll 14.
- the adhesive layer 13 sticks to the back of the underlying layer of the roller 14, so that a separate protective or cover film for the adhesive layer 13 is unnecessary.
- the adhesive layer 13 sticks airtight but releasably on the back of the adjacent layer from the cover film 1 and is thus effectively protected against drying out.
- the new cover film 1 Since the new cover film 1 has the same thickness practically over the entire width, there are no folds or kinks during winding, and the exact cylindrical shape of the roll 14 is not impaired.
- the only point at which the folded covering film 1 is thinner than it corresponds to the thickness in the area of the reinforcing strip 12 is the gap that is created between the reinforcing strip 12 and the folded edge 6. However, this gap has a negligibly small extent compared to the width of the folded structure.
- the new cover film 1 When used, the new cover film 1 can simply be unwound from the roll 14 as an endless material. There is no additional protective film for the adhesive layer 13. In addition, similar to a protective film, the adhesive layer 13 detaches from the back of the film web 2 without residues, since it adheres better to the reinforcement strip 12 than to the film web 2 itself.
- the edge-flush position of the side edge 4 and the folded edge 6 on the one hand and the reinforcement strip 12 with the side edge 3 on the other hand has the advantage that no cavities are formed between the individual turns in the end faces of the roller 14, which would make the edges sensitive to damage.
- the material of the film web in the cover film 1 can be selected relatively thick without further ado.
- the film web 2 can also be folded in more than twice or less than twice, depending on which length of the roll 14 is to be achieved for a given width of the film web, measured between the two side edges 3 and 4.

Abstract
Description
Die Erfindung geht aus von einer Abdeckfolie mit den Merkmalen des Oberbegriffs des Anspruches 1. Eine derartige Folie ist aus der US-A-4 263 347 bekannt.The invention is based on a cover film with the features of the preamble of
Eine weitere aus der Praxis bekannte Abdeckfolie besteht aus einer bandförmigen, endlos auf einer Rolle aufgewickelten Folienbahn, die längs einer Kante mit einem Klebstoffstreifen versehen ist. Der Klebstoff ist unmittelbar auf die Folienbahn aufgebracht. Hierdurch soll eine Verstärkung der Folienbahn im Bereich des Klebstoffstreifens möglichst vermieden werden, denn Verstärkungen haben beim Aufwickeln der Folienbahn zu einer Rolle zur Folge, daß der Wickel bzw. die Rolle konisch oder kegelig wird. Der Wickel ist nicht fest und kann Falten schlagen, was dann bei der weiteren Handhabung zu erheblichen Problemen führt.Another cover film known from practice consists of a band-shaped film web endlessly wound on a roll, which is provided with an adhesive strip along one edge. The adhesive is applied directly to the film web. In this way, reinforcement of the film web in the area of the adhesive strip is to be avoided as far as possible, since reinforcements have the consequence when winding the film web into a roll that the winding or the roll becomes conical or conical. The wrap is not firm and can fold, which then leads to considerable problems in further handling.
Außerdem hat bei der bekannten Abdeckfolie die Rolle, in der die Abdeckfolie geliefert wird, eine Länge entsprechend der Breite der Folienbahn.In addition, in the known cover film, the roll in which the cover film is supplied has a length corresponding to the width of the film web.
Das unmittelbare Aufbringen des Klebstoffs auf die Folienbahn führt außerdem zu Problemen bei der Anwendung, weil, wie sich herausgestellt hat, unter Umständen beim Abziehen der Folie die Folie abreißt und ein dem Klebstoffstreifen entsprechend breiter Folienstreifen auf der zu schützenden Unterlage kleben bleibt. Da die Abdeckfolie für einfache organische Lösungsmittel, die den Klebstoff auflösen würden, unlösbar ist, besteht praktisch keine Möglichkeit mehr, diesen aus Klebstoff und Abdeckfolie bestehenden Streifen von der Unterlage zu beseitigen.The direct application of the adhesive to the film web also leads to problems in use because, as it turned out, the film may tear off when the film is removed and a film strip corresponding to the adhesive strip remains stuck to the surface to be protected. Since the cover film is insoluble for simple organic solvents that would dissolve the adhesive, there is practically no longer any possibility of removing this strip consisting of adhesive and cover film from the base.
Aus der EP-A-01 87 982 ist eine Kunststoffolie zum Abdecken von Kraftfahrzeugsitzen bekannt. Diese Folie dient nur als lose Abdeckung und verfügt über keinerlei Vorkehrungen, mit deren Hilfe die Folie an dem Kraftfahrzeugsitz zu befestigen ist.A plastic film for covering motor vehicle seats is known from EP-A-01 87 982. This film only serves as a loose cover and has no precautions with which the film can be attached to the motor vehicle seat.
Um die Breite der Vorratsrolle zu vermindern, zu der die Abdeckfolie aufgewickelt ist, wird die zunächst planliegende Folie an ihren beiden Längskanten unterschiedlich breit eingeschlagen. Sodann wird die der Länge nach vorgefaltete Abdeckfolie in der Mitte zwischen den beiden entstehenden Faltkanten zu einer Art Halbschlauch zusammengeschlagen. Damit ist das entstehende Folienband wegen der unterschiedlichen Anzahl von Faltkanten an einem Rand dicker als an dem anderen Rand. Um hier einen Ausgleich zu schaffen, wird die Abdeckfolie außerdem im Bereich der Faltkante, die den Halbschlauch entstehen läßt, einmal leporelloartig nach innen geknickt, so daß an beiden Folienrändern dieselbe Anzahl von Lagen übereinanderliegt, ehe die Folienbahn zur Rolle aufgewickelt wird.In order to reduce the width of the supply roll to which the cover film is wound, the film, which is initially flat, is wrapped in different widths on its two longitudinal edges. Then the lengthwise pre-folded cover film is folded together in the middle between the two folding edges that arise to form a kind of half-tube. The resulting film tape is therefore thicker on one edge than on the other edge due to the different number of folded edges. In order to compensate for this, the cover film is also folded leporello-like inwards in the area of the folded edge that creates the half-tube, so that the same number of layers is superimposed on both film edges before the film web is wound up into a roll.
Ausgehend hiervon ist es Aufgabe der Erfindung, eine Abdeckfolie zu schaffen, bei der die Rolle, zu der die Abdeckfolie in der Lieferform aufgewickelt ist, kürzer ist als es der Breite der Folienbahn entspricht, wobei die Rolle weder kegelig ist noch lose Ränder aufweist.Proceeding from this, it is an object of the invention to provide a cover film in which the roll to which the cover film is wound in the delivery form is shorter than the width of the film web, the roll being neither conical nor having loose edges.
Diese Aufgabe wird erfindungsgemäß durch die Abdeckfolie mit den Merkmalen des Anspruches 1 gelöst.According to the invention, this object is achieved by the cover film having the features of
Die Verwendung des Verstärkungsstreifens im Bereich des Klebstoffes verhindert, daß die Folienbahn an ihren beiden Kanten, die nach dem Falten entstehen, unterschiedliche Stärke aufweist. Wenn beispielsweise die Folienbahn in Längsrichtung lediglich einmal eingeschlagen ist, hat der Verstärkungsstreifen die Dicke der Folienbahn. Dadurch ist das nach der Faltung erhaltene Band im Bereich des Klebstoffs genauso dick wie die Kante, die durch den Falz gebildet ist. Das Aufwickeln zur Rolle wird zu einer exakt zylindrischen Rolle führen. Beide Ränder sind nach dem Aufwickeln zur Rolle fest aufeinandergepreßt, was ein Eindringen von Schmutz verhindert und außerdem die Kante unempfindlicher gegen Beschädigungen macht.The use of the reinforcement strip in the area of the adhesive prevents the film web from having different thicknesses at its two edges which arise after folding. If, for example, the film web is wrapped only once in the longitudinal direction, the reinforcement strip has the thickness of the film web. As a result, the tape obtained after folding is just as thick in the area of the adhesive as the edge formed by the fold. Winding up to the roll will result in an exactly cylindrical roll. After being rolled up into a roll, both edges are pressed tightly against one another, which prevents dirt from penetrating and also makes the edge less sensitive to damage.
Besonders anwenderfreundlich wird die Abdeckfolie, wenn sich der Verstärkungsstreifen zwischen dem Klebstoff, mit dem die Folien auf die Unterlage geklebt wird, und der Folienbahn befindet. Beim Benutzen der Folie muß kein separater Streifen von dem Klebstoff abgezogen werden. Andererseits wird im gewickelten Zustand der Klebstoff von der nachfolgenden Wickellage gegen Austrocknen geschützt, weil,wegen der gleichen Dicke der Folie an beiden Kante, auch im Bereich des Klebstoffs die Wickellagen fest aufeinanderliegen.The cover film becomes particularly user-friendly if the reinforcement strip is located between the adhesive with which the film is glued to the base and the film web. When using the film, no separate strip has to be peeled off the adhesive. On the other hand, in the wound state, the adhesive is protected from drying out by the subsequent winding layer, because of the same thickness of the Foil on both edges, even in the area of the adhesive, the wrapping layers are firmly on top of each other.
Wenn eine stärkere Verkürzung der Rolle, zu der die Abdeckfolie aufgewickelt ist, erwünscht ist, kann die Folienbahn in Längsrichtung beispielsweise leporelloartig gefaltet werden, wobei die nächste Faltung in der Nähe des Klebstreifens liegt. In jedem Falle ist die Faltung so ausgeführt, daß nach der Faltung im Bereich beider Kanten des erhaltenen Bandes eine gleiche Materialdicke vorzufinden ist und daß zwischen diesen Kanten des Band jedenfalls nicht dicker ist.If a greater shortening of the roll to which the cover film is wound is desired, the film web can, for example, be folded like a leporello, the next fold being in the vicinity of the adhesive strip. In any case, the folding is carried out in such a way that after folding in the area of both edges of the tape obtained, the same material thickness is found and that in any case there is no thicker between these edges of the tape.
In der einzigen Figur der Zeichnung ist schematisiert die erfindungsgemäße Abdeckfolie perspektivisch dargestellt.In the single figure of the drawing, the cover film according to the invention is shown schematically in perspective.
Die Figur zeigt nicht maßstäblich eine Abdeckfolie 1 zum Schutz von Flächen, die bei der Bearbeitung von Nachbarflächen nicht verunreinigt werden dürfen. Die Abdeckfolie 1 besteht aus einer länglichen bandförmigen Folienbahn 2, die von zwei parallel und im Abstand voneinander verlaufenden geraden Seitenkanten 3, 4 begrenzt ist. Zwischen diesen beiden Seitenkanten 3, 4 ist die Folienbahn 2 leporelloartig gefaltet, wodurch zwei in Längsrichtung durchgehende Faltkanten 5, 6 entstehen. Hierdurch wird die Breite der Folienbahn 2 in insgesamt drei Bereiche 7, 8 und 9 aufgeteilt, wobei die Bereiche 8 und 9 deckungsgleich sind und der Bereich 7 in der Nähe der Seitenkante 3 über die Bereiche 8, 9 mit einem streifenförmigen Bereich 11 übersteht.The figure does not show a covering
Der streifenförmige Bereich 11 trägt auf derjenigen Seite, auf der sich nach der Leporellofaltung die Bereiche 8 und 9 befinden, einen Verstärkungsstreifen 12, dessen Breite etwas geringer ist als die Breite des Streifens 11 und der sich über die gesamte Länge der Folienbahn 2 erstreckt. Der Verstärkungsstreifen 12 endet seitlich an der Seitenkante 3, d.h. es steht weder der Verstärkungsstreifen 12 über die Folienbahn 2 noch die Folienbahn 2 über den Verstärkungsstreifen 12 über.The strip-
Der Verstärkungsstreifen 12 ist durch Kleben oder Schweißen mit der betreffenden Seite der Folienbahn 2 dauerhaft verbunden. Er trägt auf seiner von der Folienbahn 2 wegweisenden Seite eine Klebstoffschicht 13, die auf dem Verstärkungsstreifen 12 stärker haftet als auf den Unterlagen, an denen die Abdeckfolie 1 aufzukleben ist. Die Klebstoffschicht 13 überdeckt vollständig die von der Folienbahn 2 wegweisende Seite des Verstärkungsstreifens 12 und läuft ununterbrochen über die gesamte Länge des Verstärkungsstreifens 12 und damit der Folienbahn 2 durch.The
Die Stärke der Klebstoffschicht 13 ist vernachlässigbar dünn. Hingegen hat der Verstärkungsstreifen 12 eine Dicke oder Stärke, die der Stärke der beiden aufeinanderliegenden Bereiche 8 und 9 entspricht, d.h. die Stärke des Verstärkungsstreifens 12 ist gleich der n-fachen Stärke der Folienbahn 2, wobei n die Anzahl der Faltungen ist, längs derer die Folienbahn 2 eingeschlagen oder eingefaltet ist. Im dargestellten Fall ist die Folienbahn längs der beiden Faltkanten 5, 6, die parallel mit Abstand zueinander verlaufen, gefaltet, also zweimal gefaltet, d.h. der Verstärkungsstreifen 12 weist zweimal die Dicke der Folienbahn 2 auf.The thickness of the
Hierdurch ist die ausgestreckt flachliegende und, wie dargestellt, leporelloartig gefaltete Abdeckfolie 1 im Bereich der Seitenkante 3 genauso dick wie im Bereich der Seitenkante 4, die sich unmittelbar über der Faltkante 5 befindet. Die Seitenkante 4 und die Faltkante 5 sind deckungsgleich, so daß wiederum weder die Seitenkante 4 über die Faltkante 5 noch umgekehrt die Faltkante 5 über die Seitenkante 4 übersteht.As a result, the
Aufgrund der gezeigten Ausführung der Abdeckfolie 1 läßt sie sich zu der schematisch veranschaulichten zylindrischen Rolle 14 aufwickeln. Dabei klebt die Klebstoffschicht 13 auf der Rückseite der darunter befindlichen Lage der Rolle 14, so daß eine gesonderte Schutz- oder Abdeckfolie für die Klebstoffschicht 13 entbehrlich ist. Die Rückseite der radial innen benachbarten Windung der Rolle 14, d.h. somit die Abdeckfolie 1 selbst wirkt als Schutzfilm für die Klebstoffschicht 13. Die Klebstoffschicht 13 klebt luftdicht, aber lösbar an der Rückseite der benachbarten Lage aus der Abdeckfolie 1 und ist dadurch wirksam gegen Austrocknen geschützt.Due to the design of the
Da die neue Abdeckfolie 1 praktisch über die gesamte Breite dieselbe Dicke aufweist, entstehen beim Aufwickeln keine Falten oder Knicke bzw. es wird nicht die exakte Zylinderform der Rolle 14 beeinträchtigt. Die einzige Stelle, an der die gefaltete Abdeckfolie 1 dünner ist als es der Stärke im Bereich des Verstärkungsstreifens 12 entspricht, ist der Spalt, der zwischen dem Verstärkungsstreifen 12 und der Faltkante 6 entsteht. Dieser Spalt hat aber, verglichen mit der Breite des gefalteten Gebildes, eine vernachlässigbar geringe Ausdehnung.Since the
Die neue Abdeckfolie 1 kann bei ihrer Verwendung einfach von der Rolle 14 als Endlosmaterial abgewickelt werden. Es fällt keine zusätzliche Schutzfolie für die Klebstoffschicht 13 an. Außerdem löst sich die Klebstoffschicht 13, ähnlich wie eine Schutzfolie, rückstandfrei von der Rückseite der Folienbahn 2, da sie auf dem Verstärkungsstreifen 12 besser haftet als auf der Folienbahn 2 selbst.When used, the
Die kantenbündige Lage der Seitenkante 4 und der Faltkante 6 einerseits und des Verstärkungsstreifens 12 mit der Seitenkante 3 andererseits hat den Vorteil, daß in den Stirnseiten der Rolle 14 keinerlei Hohlräume zwischen den einzelnen Windungen entstehen, was die Kanten empfindlich gegenüber Beschädigungen machen würde.The edge-flush position of the
Schließlich kann das Material der Folienbahn bei der Abdeckfolie 1 ohne weiteres verhältnismäßig dick gewählt werden.Finally, the material of the film web in the
Abgesehen von der dargestellten leporelloartigen Faltung der Folienbahn 2 ist auch ein Einschlagen nach innen möglich, d.h. die Faltung an den Faltkanten 5, 6 erfolgt nicht in jeweils entgegengesetzter Richtung, sondern mit gleichem Sinn.Apart from the leporello-like folding of the
Außerdem kann die Folienbahn 2 auch abweichend von der Darstellung mehr als zweimal oder weniger als zweimal eingefaltet werden, je nachdem, welche Länge der Rolle 14 bei gegebener Breite der Folienbahn, gemessen zwischen den beiden Seitenkanten 3 und 4, erreicht werden soll.In addition, deviating from the illustration, the
