Definitions
- the invention relates to a cover sheet for painting and painting work that results in at least two folding layers is folded up, on a longitudinal edge strip an adhesive tape is attached to the material web, which is on the side protrudes beyond the longitudinal edge strip.
- cover sheets are mainly used for painting, Plastering, cleaning and painting work used, where large areas, such as walls, floors or windows, must be covered to prevent them from and plaster splashes, water, etc. to protect.
- the cover sheets usually consist of thin plastic films, up to 36 fold layers with longitudinal Folded edges are folded together.
- Adhesive tapes are offered, which regarding the Adhesive, mechanical properties and thickness differentiate from each other. This requires the manufacturer a variety of special adhesive tapes, around all possible combinations of properties To be able to offer.
- the folded ones Cover sheets rolled up into rolls, whereby it is necessary that the thickness of the tape at least approximately equal to the thickness of the one above the other Folding positions is.
- With a large number of Folded layers must therefore use very thick adhesive tapes due to their thickness only in relatively short Processing lengths of, for example, 100 m are available are what because of the frequent renewal of the tape rolls a short manufacturing cycle and high manufacturing costs causes.
- the object of the invention is to provide a cover sheet, which is easier and cheaper to manufacture.
- the cover sheet according to the invention has a cover tape, that is applied to the adhesive-free back of the tape is, and at least the width of the tape partially covered.
- First the tape and that The cover tape together has all the desired properties regarding the adhesive, the mechanical properties and the total thickness of the tape-cover tape combination.
- the appropriate adhesive tape is primarily based on the Type of adhesive desired selected while the Cover tape is chosen so that the total desired Overall thickness, tear strength and texture achieved becomes. For example, with three different Types of tapes and three different ones Types of cover tapes already nine different adhesive tape cover tape combinations realize. So that at relatively low inventory a variety of property combinations the tape-cover tape combination will be realized. This also allows combinations with properties that are simply made up Adhesive tape are not available.
- the thickness of the Adhesive and cover tape together at least approximately equal to the thickness of all folded layers of the material web together. This is particularly necessary if the folded material web in the longitudinal direction rolled up in a roll.
- the thickness of all folded layers and the tapes are rolled up Material web layers and the rolled up Adhesive / cover tape layers always the same total radial thickness, i.e. they are always on the same roller radius rolled up or unrolled.
- the at least roughly same thickness of the tape-cover tape combination and the folding positions on top of each other is even a requirement for rolling up the material web into one Role.
- the web of material can be unrolled such that alternatively the adhesive side of the cover tape is exposed to the adhesive tape, while the adhesive side of the tape is from the Back of the cover tape is covered.
- This will do so achieved that the rolling begins with a complete 360 ° trip alone of the cover tape of the tape underneath is peeled off.
- the web of material one of which is now a longitudinal end between the adhesive sheet and the underlying cover sheet lies, further unrolled.
- the adhesive side lies the cover sheet below, so that the material sheet with the Adhesive side of the cover sheet applied to a base can be.
- the user can have two different adhesive sides in their properties Selection so that it is always appropriate for the respective surface can choose a more suitable adhesive side.
- the cover tape covering the adhesive tape widthwise only partially.
- the cover tape does not cover the part of the adhesive tape that is glued to the material web so as to overlap one another. This prevents in the area of the overlap that the total thickness becomes too large, which would lead to an extreme roll radius or diameter when rolled up into a roll in this area.
- the number can the material web folding positions considerably up to 32 layers are increased so that material webs of unfolded up to 3 m wide to only approx Fold and roll 12 cm long roll leave, so that a comfortable working with short roles is made possible.
- the number of folds can be in one large area can be chosen freely, because the resulting Fold layer thickness always by choosing one accordingly thick shroud can be adjusted.
- the cover tape preferably also has an adhesive side on with it on the back of the tape sticks.
- the cover tape By simply sticking the cover tape on the The back of the tape is the production of the tape-cover tape combination simple and because of the multitude offered one-sided adhesive tapes variable and inexpensive.
- the adhesive side the protruding part of the tape with a removable protective tape that does not stick or only weakly covered.
- the tape increases the overall thickness, on the other hand, it offers before the actual sticking on a surface to be covered, the possibility just stop the material web and correct it to be able to. Only when the desired orientation and position of the material web is found the protective tape is removed from the tape and the tape glued to the surface.
- the adhesives used differ in particular regarding the adhesive force and its aggressiveness or compatibility with a certain surface, for example on steel, anodized aluminum, plastic, Paint, wood, glazes, etc., and in terms of their temporal stability and their sensitivity certain liquids, such as solvents, Water, etc., opposite.
- the adhesive and the cover tape can either on the Folded side of the longitudinal edge strip as a so-called Be arranged outer fold, or as an inner fold on the side of the Be arranged along the longitudinal edge.
- the cover sheet is preferably a plastic film because these films in extremely small thicknesses of up to 8-10 To be available. Such a plastic film leaves fold into very many layers so that very short rolls even with large web widths of the folded material web.
- An apparatus for producing the previously described Cover web has a material web feed device on the web of material of a processing device feeds. There is also an adhesive tape feeder and a shroud feed device is provided, the respective band also the processing device feed, in which the cover band on the Adhesive tape and the adhesive tape applied to the material web becomes.
- a cover sheet 10 for covering doors, windows, walls, furniture, body parts etc. against paint, paint, plaster and water splashes consists of a material sheet which is a matt transparent plastic sheet 14.
- the plastic sheet 14 consists of high pressure extruded polyethylene and has a thickness of approximately 10 ⁇ m . However, other, even thinner or thicker plastic films can be used.
- the plastic sheet 14 in the longitudinal direction with seven longitudinal folding edges 11a-11g, folded into eight folded positions 12a-12h.
- the seven lower folding positions 12b-12h have the same Width and are all congruent on top of each other.
- the top fold position 12a is wider than the other fold positions 12b-12h and stands with a protruding longitudinal edge strip 13 approximately 10 mm above the ones below Folded edges 11a-11c of the seven below Folded positions 12b-12h over.
- the plastic sheet 14 is therefore folded in such a way that all folded positions 12a-12h form a stack, and only the top layer 12a its protruding longitudinal edge strip 13 about 10 mm above the stack width protrudes.
- a 15-25 mm wide adhesive tape 16 is glued with its adhesive side 17 on the longitudinal edge strip 13 in the longitudinal direction, the adhesive tape 16 with 3-5 mm of its width adhering to the plastic sheet 14 so that it overlaps protrudes laterally beyond the longitudinal edge strip 13 with more than half of its width.
- a cover tape 20 with its adhesive side 21 is glued onto the adhesive-free rear side 18 of the adhesive tape 16, which has the same width as the adhesive tape 16 and completely covers the adhesive tape 16.
- the cover tape can also be made narrower than the adhesive tape to save material.
- the adhesive tape 16 is a masking tape with an adhesive that adheres well to paper, wallpaper, etc., but is easily removable without damaging the surface.
- the cover tape 20 is also a masking tape.
- the two belts 16,20 have a combined thickness of approximately 250 ⁇ m, the thickness of the overlying folded layers 12a-12h including the air enclosed by them corresponds approximately.
- the plastic sheet 14 is, as shown in Fig. 1, too a roll 24 rolled up, the longitudinal edge strips 13 and the uppermost bands 16, 20 Folded position 12a each radially outside and the remaining layers 12b-12h are arranged on the inside.
- the plastic web 14 has a width of 100 cm, so that the roller 24 at eight layers 12a-12h one Has a length of approximately 16 cm. When folding a 260 cm wide plastic sheet to 16 layers would be the length of the Roll about 20 cm including the adhesive tape 16.
- plastic sheets with a width can also be used of 300 cm and more can be used, up to 32 Folded layers folded together with a roll length of 12 cm can be.
- the total height of the tape-cover tape combination is then chosen accordingly adjusted thicker shroud.
- the shroud can always be selected according to how the (mechanical) properties of the cover tape / tape combination, for example moisture resistance or tensile strength.
- the Adhesive tape 16 is primarily due to its Adhesive properties selected.
- the adhesive of the tape 16 can have special properties for every surface have the optimal for the underground adapted properties with regard to adhesive strength, solubility and durability of the adhesive.
- the other properties of the shroud-tape combination are chosen by a suitably chosen cover band fixed.
- the roller 24 is taken in one hand, and the plastic sheet 14 on the surface in question, as in one of the figures 3 and 4 shown room wall 26, created and rolled along the room wall 26.
- the roll 24 can also be a rolling device be used.
- the adhesive tape 16 pressed onto the wall of the room 26, so that the adhesive tape 16 sticks immediately.
- the roll 24 from the glued Cover sheet 10 cut off.
- the still folded Plastic sheet 14 is glued to the room wall 26, the stack of folded layers due to electrostatic Forces held together between the folded positions 12a-12h becomes.
- the lowest folded position 12h lies across the entire width on the room wall 26 while from the top layer 12a only the protruding longitudinal edge strip 13 in cross section S-shaped against the room wall 26 and is stuck.
- the plastic sheet 14 is now on unfolded their entire width by the bottom layer is pulled down 12h. there unfold the folded layers 12b-12h to a smooth the wide material web 14 adjoining the room wall 26, as shown in Fig. 4.
- the plastic sheet 14 When making the cover sheet, the plastic sheet 14, the adhesive tape 16 and the cover tape 18 separately fed to a processing device in which the tape 16 on the plastic sheet 14 and that Cover tape 20 is applied to the adhesive tape 16.
- a processing device in which the tape 16 on the plastic sheet 14 and that Cover tape 20 is applied to the adhesive tape 16.
- By separating adhesive and cover tape 16.20 can thinner adhesive and cover tapes are used than if the required total thickness with a single band should be filled out. Therefore, with one given maximum tape roll diameter significantly longer rolls of tape and shroud of one length use of several 100 m. This will make the manufacturing cycle until the empty reels are replaced considerably extended, which saves manufacturing costs become.
Description
Die Erfindung bezieht sich auf eine Abdeckbahn für Mal- und Lackierarbeiten, die zu mindestens zwei Faltlagen zusammengefaltet ist, wobei an einem Längsrandstreifen der Materialbahn ein Klebeband befestigt ist, das seitlich über den Längsrandstreifen übersteht.The invention relates to a cover sheet for painting and painting work that results in at least two folding layers is folded up, on a longitudinal edge strip an adhesive tape is attached to the material web, which is on the side protrudes beyond the longitudinal edge strip.
Derartige Abdeckbahnen werden hauptsächlich für Mal-, Verputz-, Reinigungs- und Lackierarbeiten verwendet, bei denen große Flächen, beispielsweise Wände, Fußböden oder Fenster, abgedeckt werden müssen, um sie vor Farb- und Putzspritzern, Wasser u.ä. zu schützen. Die Abdeckbahnen bestehen in der Regel aus dünnen Kunststoffolien, die zu bis zu 36 Faltlagen mit längslaufenden Faltkanten zusammengefaltet sind. Für verschiedene Anwendungszwecke werden die Abdeckbahnen mit verschiedenen Klebebändern angeboten, die sich hinsichtlich des Klebers, der mechanischen Eigenschaften und der Dicke voneinander unterscheiden. Dies erfordert beim Hersteller der Abdeckbahnen eine Vielzahl von speziellen Klebebändern, um alle möglichen Eigenschaftskombinationen anbieten zu können. In der Regel werden die zusammengefalteten Abdeckbahnen zu Rollen zusammengerollt, wobei es erforderlich ist, daß die Dicke des Klebebandes mindestens ungefähr gleich der Dicke der übereinanderliegenden Faltlagen ist. Bei einer großen Anzahl von Faltlagen müssen daher sehr dicke Klebebänder verwendet werden, die aufgrund ihrer Dicke nur in relativ kurzen Verarbeitungslängen von beispielsweise 100 m erhältlich sind, was wegen des häufigen Erneuerns der Klebebandrollen einen kurzen Herstellungszyklus und hohe Herstellungskosten bewirkt.Such cover sheets are mainly used for painting, Plastering, cleaning and painting work used, where large areas, such as walls, floors or windows, must be covered to prevent them from and plaster splashes, water, etc. to protect. The cover sheets usually consist of thin plastic films, up to 36 fold layers with longitudinal Folded edges are folded together. For various purposes are the cover sheets with different Adhesive tapes are offered, which regarding the Adhesive, mechanical properties and thickness differentiate from each other. This requires the manufacturer a variety of special adhesive tapes, around all possible combinations of properties To be able to offer. As a rule, the folded ones Cover sheets rolled up into rolls, whereby it is necessary that the thickness of the tape at least approximately equal to the thickness of the one above the other Folding positions is. With a large number of Folded layers must therefore use very thick adhesive tapes due to their thickness only in relatively short Processing lengths of, for example, 100 m are available are what because of the frequent renewal of the tape rolls a short manufacturing cycle and high manufacturing costs causes.
Aufgabe der Erfindung ist es, eine Abdeckbahn zu schaffen, die einfacher und preiswerter herstellbar ist.The object of the invention is to provide a cover sheet, which is easier and cheaper to manufacture.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1 solved.
Die erfindungsgemäße Abdeckbahn weist ein Deckband auf, das auf die kleberfreie Rückseite des Klebebandes aufgebracht ist, und das das Klebeband in der Breite zumindest teilweise bedeckt. Erst das Klebeband und das Deckband zusammen haben alle gewünschten Eigenschaften bzgl. des Klebers, der mechanischen Eigenschaften und der Gesamtdicke der Klebeband- Deckband-Kombination. Das passende Klebeband wird in erster Linie nach der Art des gewünschten Klebers ausgewählt, während das Deckband so gewählt wird, daß insgesamt die gewünschte Gesamtdicke, Reißfestigkeit und Beschaffenheit erreicht wird. So lassen sich beispielsweise mit drei verschiedenen Arten von Klebebändern und drei verschiedenen Arten von Deckbändern bereits neun verschiedene Klebeband-Deckband-Kombinationen realisieren. Damit kann bei relativ geringer Lagerhaltung eine Vielzahl von Eigenschaftskombinationen der Klebeband-Deckband-Kombination realisiert werden. Dadurch lassen sich auch Kombinationen mit Eigenschaften herstellen, die als einfach konfektioniertes Klebeband nicht verfügbar sind. Durch die Verwendung von zwei Bändern ist deren jeweilige Dicke geringer als wenn die gewünschte Dicke ein einziges Band aufweisen müßte. Durch die verringerte Dicke des Klebe- bzw. Deckbandes sind die Verarbeitungslängen größer, so daß der Produktionsprozeß zur Auswechslung einer leeren Bandrolle seltener unterbrochen werden muß. Dadurch werden Herstellungskosten eingespart.The cover sheet according to the invention has a cover tape, that is applied to the adhesive-free back of the tape is, and at least the width of the tape partially covered. First the tape and that The cover tape together has all the desired properties regarding the adhesive, the mechanical properties and the total thickness of the tape-cover tape combination. The appropriate adhesive tape is primarily based on the Type of adhesive desired selected while the Cover tape is chosen so that the total desired Overall thickness, tear strength and texture achieved becomes. For example, with three different Types of tapes and three different ones Types of cover tapes already nine different adhesive tape cover tape combinations realize. So that at relatively low inventory a variety of property combinations the tape-cover tape combination will be realized. This also allows combinations with properties that are simply made up Adhesive tape are not available. Through the The use of two tapes is their respective thickness less than if the desired thickness is a single Should have tape. Due to the reduced thickness of the Adhesive or cover tape are the processing lengths bigger, so the production process for replacement an empty tape roll are interrupted less often got to. This saves manufacturing costs.
In einer bevorzugten Ausführungsform ist die Dicke des Klebe- und Deckbandes zusammen mindestens ungefähr gleich der Dicke aller Faltlagen der Materialbahn zusammen. Dies ist insbesondere dann erforderlich, wenn die zusammengefaltete Materialbahn in Längsrichtung zu einer Rolle zusammengerollt ist. Durch die gleiche Dicke aller Faltlagen und der Bänder haben die aufeinandergerollten Materialbahnlagen und die aufeinandergerollten Klebe-/Deckbandlagen stets dieselbe radiale Gesamtdicke, d.h. sie werden stets auf demselben Rollenradius auf- oder abgerollt. Die mindestens ungefähr gleiche Dicke der Klebeband-Deckband-Kombination und der aufeinanderliegenden Faltlagen ist sogar Voraussetzung für das Zusammenrollen der Materialbahn zu einer Rolle.In a preferred embodiment, the thickness of the Adhesive and cover tape together at least approximately equal to the thickness of all folded layers of the material web together. This is particularly necessary if the folded material web in the longitudinal direction rolled up in a roll. By the same The thickness of all folded layers and the tapes are rolled up Material web layers and the rolled up Adhesive / cover tape layers always the same total radial thickness, i.e. they are always on the same roller radius rolled up or unrolled. The at least roughly same thickness of the tape-cover tape combination and the folding positions on top of each other is even a requirement for rolling up the material web into one Role.
Bei zu einer Rolle zusammengerollter Materialbahn kann die Materialbahn derart abgerollt werden, daß alternativ zum Klebeband die Klebeseite des Deckbandes freiliegt, während die Klebeseite des Klebebandes von der Rückseite des Deckbandes bedeckt wird. Dies wird dadurch erreicht, daß das Abrollen damit beginnt, daß ein kompletter 360°-Törn alleine des Deckbandes von dem darunterliegenden Klebeband abgezogen wird. Anschließend wird die Materialbahn, deren eines Längsende nun zwischen der Klebebahn und der darunterliegenden Deckbahn liegt, weiter abgerollt. Nun liegt die Klebeseite der Deckbahn unten, so daß die Materialbahn mit der Klebeseite der Deckbahn auf eine Unterlage aufgebracht werden kann. Auf diese Weise können dem Benutzer zwei in ihren Eigenschaften verschiedene Klebeseiten zur Auswahl, so daß er stets die für den jeweiligen Untergrund geeignetere Klebeseite wählen kann.When the material web is rolled up into a roll, the web of material can be unrolled such that alternatively the adhesive side of the cover tape is exposed to the adhesive tape, while the adhesive side of the tape is from the Back of the cover tape is covered. This will do so achieved that the rolling begins with a complete 360 ° trip alone of the cover tape of the tape underneath is peeled off. Subsequently becomes the web of material, one of which is now a longitudinal end between the adhesive sheet and the underlying cover sheet lies, further unrolled. Now the adhesive side lies the cover sheet below, so that the material sheet with the Adhesive side of the cover sheet applied to a base can be. In this way, the user can have two different adhesive sides in their properties Selection so that it is always appropriate for the respective surface can choose a more suitable adhesive side.
Bei der Verwendung dickerer Materialbahnen, beispielsweise mit einer Dicke von 50-100 µm, bedeckt das Deckband breitenmäßig das Klebeband nur teilweise. Das Deckband bedeckt insbesondere den Teil des Klebebandes nicht, der mit der Materialbahn übereinanderlappend verklebt ist. Dadurch wird im Bereich der Überlappung verhindert, daß die Gesamtdicke zu groß wird, was beim Zusammenrollen zu einer Rolle in diesem Bereich zu einem extremen Rollenradius bzw. -durchmesser führen würde.When using thicker material sheets, for example having a thickness of 50-100 μ m, the cover tape covering the adhesive tape widthwise only partially. In particular, the cover tape does not cover the part of the adhesive tape that is glued to the material web so as to overlap one another. This prevents in the area of the overlap that the total thickness becomes too large, which would lead to an extreme roll radius or diameter when rolled up into a roll in this area.
Durch Verwendung eines dicken Deckbandes kann die Anzahl der Materialbahn-Faltlagen beträchtlich auf bis zu 32 Lagen erhöht werden, so daß sich Materialbahnen von auseinandergefaltet bis zu 3 m Breite zu einer nur ungefähr 12 cm langen Rolle zusammenfalten und -rollen lassen, so daß ein bequemes Arbeiten mit kurzen Rollen ermöglicht wird. Die Anzahl der Faltlagen kann in einem großen Bereich frei gewählt werden, da die dadurch entstehende Faltlagendicke stets durch Wahl eines entsprechend dicken Deckbandes angepaßt werden kann. By using a thick cover tape, the number can the material web folding positions considerably up to 32 layers are increased so that material webs of unfolded up to 3 m wide to only approx Fold and roll 12 cm long roll leave, so that a comfortable working with short roles is made possible. The number of folds can be in one large area can be chosen freely, because the resulting Fold layer thickness always by choosing one accordingly thick shroud can be adjusted.
Vorzugsweise weist das Deckband ebenfalls eine Klebeseite auf, mit der es auf der Rückseite des Klebebandes klebt. Durch einfaches Aufkleben des Deckbandes auf die Rückseite des Klebebandes ist die Herstellung der Klebeband-Deckband-Kombination einfach und wegen der Vielzahl angebotener einseitig klebender Bänder variabel und preiswert.The cover tape preferably also has an adhesive side on with it on the back of the tape sticks. By simply sticking the cover tape on the The back of the tape is the production of the tape-cover tape combination simple and because of the multitude offered one-sided adhesive tapes variable and inexpensive.
In einer bevorzugten Ausgestaltung ist die Kleberseite des überstehenden Teiles des Klebebandes mit einem entfernbaren nicht oder nur schwach klebenden Schutzband bedeckt. Zum einen erhöht das Klebeband die Gesamtdicke, zum anderen bietet es vor dem eigentlichen Festkleben auf einem abzudeckenden Untergrund die Möglichkeit, die Materialbahn zunächst nur anzuhalten und noch korrigieren zu können. Erst wenn die gewünschte Ausrichtung und Position der Materialbahn gefunden ist, wird das Schutzband von dem Klebeband entfernt und das Klebeband auf den Untergrund aufgeklebt.In a preferred embodiment, the adhesive side the protruding part of the tape with a removable protective tape that does not stick or only weakly covered. Firstly, the tape increases the overall thickness, on the other hand, it offers before the actual sticking on a surface to be covered, the possibility just stop the material web and correct it to be able to. Only when the desired orientation and position of the material web is found the protective tape is removed from the tape and the tape glued to the surface.
Die verwendeten Kleber unterscheiden sich insbesondere hinsichtlich der Klebekraft und ihrer Aggressivität auf bzw. Verträglichkeit mit einem bestimmten Untergrund, beispielsweise auf Stahl, eloxiertes Aluminium, Kunststoff, Lackierungen, Holz, Lasuren etc., und hinsichtlich ihrer zeitlichen Stabilität und ihrer Empfindlichkeit bestimmten Flüssigkeiten, beispielsweise Lösungsmittel, Wasser, etc., gegenüber.The adhesives used differ in particular regarding the adhesive force and its aggressiveness or compatibility with a certain surface, for example on steel, anodized aluminum, plastic, Paint, wood, glazes, etc., and in terms of their temporal stability and their sensitivity certain liquids, such as solvents, Water, etc., opposite.
Das Klebe- und das Deckband können entweder auf der Faltlagenseite des Längsrandstreifens als sogenannte Außenfaltung angeordnet sein, oder aber als Innenfaltung auf der den Faltlagen gegenüberliegenden Seite des Längsrandstreifens angeordnet sein. The adhesive and the cover tape can either on the Folded side of the longitudinal edge strip as a so-called Be arranged outer fold, or as an inner fold on the side of the Be arranged along the longitudinal edge.
Die Abdeckbahn ist vorzugsweise eine Kunststoffolie, da diese Folien in extrem geringen Dicken von bis zu 8-10 Um erhältlich sind. Eine derartige Kunststoffolie läßt sich zu sehr vielen Lagen zusammenfalten, so daß sich auch bei großen Materialbahnbreiten sehr kurze Rollen der zusammengefalteten Materialbahn realisieren lassen.The cover sheet is preferably a plastic film because these films in extremely small thicknesses of up to 8-10 To be available. Such a plastic film leaves fold into very many layers so that very short rolls even with large web widths of the folded material web.
Eine Vorrichtung zur Herstellung der zuvor beschriebenen Abdeckbahn weist eine Materialbahn-Zuführvorrichtung auf, die die Materialbahn einer Verarbeitungsvorrichtung zuführt. Ferner sind eine Klebeband-Zuführvorrichtung und eine Deckband-Zuführvorrichtung vorgesehen, die das jeweilige Band ebenfalls der Verarbeitungsvorrichtung zuführen, in der das Deckband auf das Klebeband und das Klebeband auf die Materialbahn aufgebracht wird. Bei einer erforderlichen Mindestgesamtdicke von Klebe- und Deckbahn ist durch die Zweiteilung des Bandes in ein Klebeband und ein Deckband die Verwendung längerer Bandrollen bei der Herstellung möglich, was ein selteneres Anhalten der Klebebahn- bzw. der Deckband-Zuführvorrichtung erforderlich macht. Dadurch ist die Herstellung vereinfacht.An apparatus for producing the previously described Cover web has a material web feed device on the web of material of a processing device feeds. There is also an adhesive tape feeder and a shroud feed device is provided, the respective band also the processing device feed, in which the cover band on the Adhesive tape and the adhesive tape applied to the material web becomes. With a required minimum total thickness of adhesive and cover sheet is due to the division in two use the tape in an adhesive tape and a cover tape longer rolls of tape possible during production, which means that the adhesive tape or the shroud feeder requires. Thereby manufacturing is simplified.

Faltlagen 12b-12h über. Die Kunststoffbahn 14 ist also
derart zusammengefaltet, daß alle Faltlagen 12a-12h
einen Stapel bilden, und nur die oberste Lage 12a mit
ihrem überstehenden Längsrandstreifen 13 ca. 10 mm über
die Stapelbreite hinausragt.As shown in Figs. 1-3, the
Wie u.a. in Fig. 1 dargestellt, ist auf dem Längsrandstreifen
13 in Längsrichtung ein 15-25 mm breites Klebeband
16 mit seiner Kleberseite 17 aufgeklebt, wobei
das Klebeband 16 mit 3-5 mm seiner Breite auf der
Kunststoffbahn 14 überlappend klebt, so daß es mit mehr
als der Hälfte seiner Breite seitlich über den Längsrandstreifen
13 übersteht. Auf die kleberfreie Rückseite
18 des Klebebandes 16 ist ein Deckband 20 mit seiner
Kleberseite 21 aufgeklebt, das die gleiche Breite wie
das Klebeband 16 hat und das Klebeband 16 vollständig
bedeckt. Das Deckband kann jedoch auch zur Materialersparnis
schmaler als das Klebeband ausgebildet sein.
Das Klebeband 16 ist ein Kreppband mit einem Kleber,
der gut auf Papier, Tapeten etc. haftet, jedoch ohne
Beschädigung des Untergrundes leicht wieder entfernbar
ist. Das Deckband 20 ist ebenfalls ein Kreppband. Die
beiden Bänder 16,20 zusammen haben eine Dicke von ungefähr
250 µm, was ungefähr der Dicke der übereinanderliegenden
Faltlagen 12a-12h einschließlich der von ihnen
eingeschlossenen Luft entspricht.As shown inter alia in Fig. 1, a 15-25 mm wide
Die Kunststoffbahn 14 ist, wie in Fig. 1 gezeigt, zu
einer Rolle 24 zusammengerollt, wobei die den Längsrandstreifen
13 und die Bänder 16,20 aufweisende oberste
Faltlage 12a jeweils radial außenliegend und die
übrigen Lagen 12b-12h innenliegend angeordnet sind.The
Die Kunststoffbahn 14 hat aufgefaltet eine Breite von
100 cm, so daß die Rolle 24 bei acht Lagen 12a-12h eine
Länge von ungefähr 16 cm hat. Bei Faltung einer 260 cm
breiten Kunststoffbahn zu 16 Lagen wäre die Länge der
Rolle etwa 20 cm einschließlich des Klebebandes 16.The
Es können jedoch auch Kunststoffbahnen mit einer Breite
von 300 cm und mehr verwendet werden, die zu bis zu 32
Faltlagen bei einer Rollenlänge von 12 cm zusammengefaltet
werden können. Die Gesamthöhe der Klebeband-Deckband-Kombination
wird dann durch Wahl eines entsprechend
dickeren Deckbandes angepaßt. Das Deckband
kann dabei stets auch danach ausgewählt werden, wie die
(mechanischen) Eigenschaften der Deckband-Klebeband-Kombination,
beispielsweise die Feuchtigkeitsbeständigkeit
oder Reißfestigkeit, ausgebildet sein sollen. Das
Klebeband 16 wird dagegen in erster Linie aufgrund seiner
Klebeeigenschaften ausgewählt. Der Kleber des Klebebandes
16 kann für jeden Untergrund spezielle Eigenschaften
aufweisen, die die für den Untergrund optimal
angepaßten Eigenschaften bzgl. der Haftfestigkeit, Löslichkeit
und Zeitbeständigkeit des Klebers aufweisen.
Die übrigen Eigenschaften der Deckband-Klebeband-Kombination
werden durch ein entsprechend gewähltes Deckband
festgelegt.However, plastic sheets with a width can also be used
of 300 cm and more can be used, up to 32
Folded layers folded together with a roll length of 12 cm
can be. The total height of the tape-cover tape combination
is then chosen accordingly
adjusted thicker shroud. The shroud
can always be selected according to how the
(mechanical) properties of the cover tape / tape combination,
for example moisture resistance
or tensile strength. The
Zum Abdecken einer Fläche, um sie beispielsweise bei
Mal- und Lackierarbeiten gegen Farb- und Lackspritzer
zu schützen, wird die Rolle 24 in eine Hand genommen,
und die Kunststoffbahn 14 an der betreffenden Fläche,
wie an einer in den Fign. 3 und 4 gezeigten Raumwand
26, angelegt und längs der Raumwand 26 abgerollt. Zum
Abrollen der Rolle 24 kann auch eine Abrollvorrichtung
eingesetzt werden. Mit der anderen Hand wird das Klebeband
16 auf die Raumwand 26 gedrückt, so daß das Klebeband
16 sofort festklebt. Nach dem Abrollen der gewünschten
Länge wird die Rolle 24 von der aufgeklebten
Abdeckbahn 10 abgeschnitten. Die noch zusammengefaltete
Kunststoffbahn 14 ist an der Raumwand 26 festgeklebt,
wobei der Faltlagenstapel aufgrund elektrostatischer
Kräfte zwischen den Faltlagen 12a-12h zusammengehalten
wird. Die unterste Faltlage 12h liegt auf ganzer Breite
an der Raumwand 26 an, während von der obersten Lage
12a nur der überstehende Längsrandstreifen 13 im Querschnitt
S-förmig verlaufend an der Raumwand 26 anliegt
und festgeklebt ist. Die Kunststoffbahn 14 wird nun auf
ihre gesamte Breite auseinandergefaltet, indem die
unterste Lage 12h nach unten gezogen wird. Dabei
entfalten sich die Faltlagen 12b-12h zu einer glatt an
der Raumwand 26 anliegenden breiten Materialbahn 14,
wie in Fig. 4 dargestellt.To cover a surface, for example when
Painting and painting work against paint and paint splashes
to protect, the
Bei der Herstellung der Abdeckbahn werden die Kunststoffbahn
14, das Klebeband 16 und das Deckband 18 getrennt
einer Verarbeitungsvorrichtung zugeführt, in der
das Klebeband 16 auf die Kunststoffbahn 14 und das
Deckband 20 auf das Klebeband 16 aufgebracht wird.
Durch die Trennung von Klebe- und Deckband 16,20 können
dünnere Klebe- und Deckbänder verwendet werden als wenn
die erforderliche Gesamtdicke durch ein einziges Band
ausgefüllt werden müßte. Daher lassen sich bei einem
gegebenen maximalen Bandrollendurchmesser erheblich
längere Klebeband- und Deckbandrollen von einer Länge
von mehreren 100 m verwenden. Dadurch wird der Herstellungszyklus
bis zum Auswechseln der leeren Bandrollen
erheblich verlängert, wodurch Herstellungskosten eingespart
werden.When making the cover sheet, the
Zur Konfiguration einer Klebeband-Deckband-Kombination mit bestimmten mechanischen Eigenschaften und Klebeeigenschaften können Standardbänder verwendet werden, die leicht verfügbar in verschiedenen und ggf. auch sehr großen Längen und preiswert erhältlich sind. Dadurch sind die Materialkosten für das Klebe- und Deckband zusammen häufig geringer als wenn ein einziges spezielles Band mit allen diesen Eigenschaften hergestellt oder eingekauft werden müßte.To configure an adhesive tape / cover tape combination with certain mechanical properties and adhesive properties standard tapes can be used easily available in different and possibly also very large lengths and inexpensive are available. Thereby are the material costs for the adhesive and cover tape together often less than when a single special Tape made with all of these properties or would have to be bought.
