Definitions
- the invention relates to a fabric in the form of a roof underlay according to the preamble of claim 1.
- a generic roof underlay according to the preamble of claim 1 describes the DE 102 01152 A1 ,
- the web described there carries an adhesive layer on each of its two longitudinal sides, wherein the adhesive layers are each arranged on a different broadside surface, so that two webs to be laid next to one another can be glued together in an overlapping region by applying the adhesive layers there.
- the DE 10 2005 017161 A1 describes a similar sheet.
- the adhesive layers are covered there by a passive cover film, which must be removed before bonding the two webs.
- the DE 296 18 359 U1 describes a heat protection device consisting of two parts, each consisting of a metal sheet and which are connected by gluing, tightening or crimping together.
- the edge region of one of the two metal sheets is provided with a magnetic tape, with which it can be connected to a magnetic substrate.
- the EP 0 882 420 A2 describes a double-sided adhesive tape for carpet fixation.
- the carpet fixation can be done there by magnetic force.
- the back of the carpet is equipped with a self-adhesive magnetic foil.
- the adhesive layers facing thereon must be brought against each other. You do not just have to touch it. It Also, a slight initial pressure on the adhesive bond must be exercised so that it comes to a permanent bond. As long as the webs are laid on a solid surface, for example a formwork, this pressure can be exerted on the uppermost web. If the webs are not laid on a solid surface, but depend, for example, freely between two rafters, it requires an additional technique to apply the necessary contact or contact pressure for the bonding on the contact zone of the two adhesive layers.
- the DE 20 2005 011 169 U1 describes a building board, which is connectable to another building board via a connection strip, wherein two contact surfaces are brought against each other.
- a sealant is applied to the two contact surfaces and achieved a sufficient sealing effect by its attractive forces (eg, magnetic or electrostatic nature).
- the DE 199 54 960 A1 describes an adhesive that is equipped with magnetic nanoparticles. This should allow a simpler separation of adhesive-containing waste.
- the invention has for its object to improve a generic roof underlay with respect to their installation properties.
- edge areas are not only glued together.
- the edge regions are additionally magnetically equipped in such a way that the overlapping edge regions are attracted by a magnetic attraction force from a spacer layer into a contact position, in which the magnetic force increasing as the distance decreases exerts an initial pressure which achieves an initial adhesion to the adhesive connection, to which either one of the two adhesive layers with a ferromagnetic Metal powder, in particular iron powder added and the other adhesive layer is mixed with a permanent magnetic powder, or an edge region has a strip of a magnetic material and the other edge region with a strip of ferromagnetic material.
- the force required for the contact or the contact pressure is not exerted by the external pressure but by the magnetic attraction of the two adhesive layers.
- the attraction has a range that is sufficiently large to attract two slightly superimposed, unconnected adhesive layers from a distance of a few millimeters to a contact position. As the magnetic attraction increases as the distance between the two adhesive layers decreases, it not only exerts a force to pull film portions in a region between two rafters to a touch position. When between two rafters freely sagging underlays often occurs due to the different sags of the underlays in the overlap region a gap that must be sealed to prevent Switzerland Kunststoffus für en heat loss.
- a significant advantage of the underlay sheet according to the invention is that the formation of such a gap due to the attractive force of the two edge regions is avoided from the outset.
- the magnetic force is also able to exert an initial pressure on the adhesive joint, so that the required initial adhesion is achieved.
- the magnetic forces exert a permanent slight pressure on the connection, resulting in a secure adhesive connection over time.
- the two strip-shaped adhesive layers are preferably equipped differently. They are equipped to attract themselves magnetically.
- An adhesive layer can be mixed, for example, with a permanent magnetic magnetic powder. This may be added to the viscous coatable adhesive.
- the other adhesive layer may be mixed with a ferromagnetic powder so that the two layers attract each other magnetically. But it is also possible that the materials are applied separately from each other on the respective edge region of the sheet. Thus, in a first layer, the respective permanent magnetic or ferromagnetic powder can be applied to the edge region of the fabric.
- the adhesive layer can then be applied only consisting of an adhesive layer.
- an adhesive layer come in both variants, the common materials into consideration, which are able to exert adhesion forces or cohesive forces on each other.
- such adhesives are used which activate when touched and exert adhesive forces.
- the adhesive may in particular contain adhesive plastic or rubber components, the interaction of which unfolds an adhesive effect.
- the film may have a multilayer structure and have a nonwoven.
- the film has a nonwoven layer and a water-barrier film layer.
- the adhesive layers can also consist of a hotmelt material. They can consist of the same material or else of different materials, which unfold an adhesive effect only when contacting. In particular, it is provided that only one adhesive layer is tacky from the surface and the other layer is not tacky.
- the adhesive layer can consist of a first, non-adhesive strip which has only the magnetic properties. On this strip then the actual adhesive layer is glued. At least one adhesive layer is covered by a passive cover strip. Both adhesive layers are preferably covered by such a cover strip.
- the invention also relates to a roof underlay, in which only one edge region has a self-adhesive layer. This can be covered with a cover strip.
- the other edge area has merely an adhesive contact surface which has such a surface finish that the adhesive layer can make an adhesive connection with this adhesive contact surface.
- the adhesive contact surface is preferably formed by a polymer. Such a polymer strip is firmly connected to the edge region.
- the polymer can be painted, welded or glued. This type of bonding is particularly provided in roof underlays, which have a nonwoven surface.
- the adhesive contact surface has a greater width than the adhesive layer of the other edge region, so that it is ensured that in the overlap region always takes place a proper bonding.
- FIG. 1 schematically shows a part perspective view of an arrangement of three juxtaposed roof underlays 1, each having at least one nonwoven layer and a water-barrier film layer.
- the roof underlays can also be designed in one layer.
- the roof underlay sheet 1 On the left is an already glued joint between two mutually parallel roofing underlayment 1 shown.
- the adhesive layer 2 extends along the longitudinal edge of the roof underlay sheet 1 and is provided with an adhesive layer 3 one in the middle of the FIG. 1 bonded roof underlay 1 glued.
- the adhesive layer 3, which likewise runs in the edge region, is arranged on the broadside pointing downwards and contains a powder of a permanent magnetic material.
- FIG. 1 Right in the FIG. 1 is a third roof underlay 1 before the bonding of the two adhesive layers 2, 3 shown.
- Each of the two adhesive layers 2, 3 is covered by a cover strip 4, which only slightly adheres to the adhesive surface of the respective adhesive layer 2, 3 and to prevent fouling of the adhesive layer.
- the cover strips 4 are first removed from the adhesive layers 2, 3. Then, the adhesive layers 2, 3 are brought into a superimposition. If the lower film 1 hangs, for example, between two rafters, it is attracted to the adhesive layer 3 of the upper film 1 in the area of the adhesive layer 2. This is done via the magnetic interaction between the permanent magnetic powder and the ferromagnetic powder.
- the latter may be an iron powder.
- the magnetic attraction between the two adhesive layers 2, 3 is sufficiently large to overcome a typical laying gap 20.
- the two adhesive layers 2, 3 attract and come into touching contact, so that an initial bonding of the two adhesive layers 2, 3 takes place.
- the magnetic forces also ensure that a permanent slight pressure on the interface between the two adhesive layers 2, 3 is exercised. This leads over time to a secure adhesive connection between the two roof underlays. 1

- An adhesive layer 2, 3 was then applied to each of the two strips.
- the adhesive layers 2, 3 may be formed of different materials, which develop an adhesive effect only when in contact with each other. It is also possible at all to make one or both adhesive layers 2, 3 sticky (not tack-free). Alternatively, only one layer may be tacky and the other layer may not be tacky, for example as a polymer layer, primer or the like.
- a strip can also be glued or welded onto one of the two surfaces of the edge region 1 '.
- the edge region has an adhesive layer 2, which is covered by a cover strip 4.
- the other edge region 1 " is provided with a magnetic strip 5.
- the roof underlay 1 is made up of several layers, so that above and below the magnetic strip 5 or the metal strip 6 lies a layer of the roof underlay sheet 1
- the edge region 1 " also carries an adhesive layer 2, which is covered with a cover strip 4. Be the two cover strips 4 deducted, the two adhesive layers 2 can adhere directly to each other.
- the magnetic attraction between the metal strip 6 and the magnetic strip 5 ensures that the two edge regions 1 ', 1 "attract each other before bonding, thereby preventing the formation of a gap in the area of slack between two rafters.
- the adhesive layer 3, which is applied to the other edge region 1 ", is not self-adhesive but is formed by a polymer which has a smooth surface High cohesive forces occur between the adhesive layer 2 and the adhesive contact surface 3 when the two surfaces are brought into contact with each other, Such an adhesive contact surface is provided in particular with such roof underlays 1, which have a rough surface

Um die Randbereiche der nebeneinander zu verlegenden Bahnen miteinander zu verkleben, müssen die dort aufeinander zu weisenden Klebeschichten gegeneinander gebracht werden. Sie müssen sich dabei nicht nur berühren. Es muss auch ein geringer anfänglicher Druck auf die Klebeverbindung ausgeübt werden, damit es zu einer dauerhaften Verklebung kommt. Solange die Bahnen auf einem festen Untergrund, zum Beispiel einer Schalung verlegt werden, kann dieser Druck über die zuoberst liegende Bahn ausgeübt werden. Werden die Bahnen nicht auf einem festen Untergrund verlegt, sondern hängen beispielsweise frei zwischen zwei Dachsparren durch, erfordert es eine zusätzliche Technik, den für die Verklebung notwendigen Kontakt bzw. Anpressdruck auf die Berührungszone der beiden Klebeschichten aufzubringen.In order to bond the edge regions of the webs to be laid next to one another, the adhesive layers facing thereon must be brought against each other. You do not just have to touch it. It Also, a slight initial pressure on the adhesive bond must be exercised so that it comes to a permanent bond. As long as the webs are laid on a solid surface, for example a formwork, this pressure can be exerted on the uppermost web. If the webs are not laid on a solid surface, but depend, for example, freely between two rafters, it requires an additional technique to apply the necessary contact or contact pressure for the bonding on the contact zone of the two adhesive layers.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Dachunterspannbahn hinsichtlich ihrer Verlegeeigenschaften zu verbessern.The invention has for its object to improve a generic roof underlay with respect to their installation properties.
Gelöst wird die Aufgabe dadurch, dass die Randbereiche nicht nur miteinander verklebbar sind. Die Randbereiche sind zusätzlich derart magnetisch ausgerüstet, dass sich die sich überlappenden Randbereiche durch eine magnetische Anziehungskraft aus einer Abstandslage in eine Berührungslage anziehen, in der die sich bei der Verringerung des Abstandes vergrößernde Magnetkraft einen eine Anfangsanhaftung erzielenden Initialdruck auf die Klebeverbindung ausübt, wozu entweder eine der beiden Klebeschichten mit einem ferromagnetischen Metallpulver, insbesondere Eisenpulver versetzt und die andere Klebeschicht mit einem permanent magnetischen Pulver versetzt ist, oder ein Randbereich einen Streifen aus einem magnetischen Material und der andere Randbereich mit einem Streifen aus ferromagnetischem Material aufweist. Zufolge dieser Ausgestaltung wird die für den Kontakt oder den Anpressdruck erforderliche Kraft nicht durch den äußeren Druck, sondern durch die magnetische Anziehungskraft der beiden Klebeschichten ausgeübt. Die Anziehungskraft hat dabei eine Reichweite, die ausreichend groß ist, um zwei geringfügig übereinanderliegende, unverbundene Klebeschichten aus einer Abstandslage von wenigen Millimetern bis in eine Berührungslage anzuziehen. Da die magnetische Anziehungskraft sich vergrößert, wenn sich der Abstand zwischen den beiden Klebeschichten verringert, übt sie nicht nur eine Kraft aus, mit der Folienabschnitte in einem Bereich zwischen zwei Dachsparren in eine Berührungsposition gezogen werden. Bei zwischen zwei Dachsparren frei durchhängenden Unterspannbahnen tritt aufgrund des unterschiedlichen Durchhangs der Unterspannbahnen im Überlappungsbereich oftmals ein Spalt auf, der zur Vermeidung von zugluftbedingten Wärmeverlusten abgedichtet werden muss. Ein wesentlicher Vorteil der erfindungsgemäßen Unterspannbahn besteht darin, dass die Entstehung eines derartigen Spalts aufgrund der Anziehungskraft der beiden Randbereiche von vorneherein vermieden wird. Die Magnetkraft ist darüber hinaus auch in der Lage, einen Initialdruck auf die Klebeverbindung auszuüben, damit die erforderliche Anfangshaftung erzielt wird. Durch die magnetischen Kräfte wird ein dauerhafter leichter Druck auf die Verbindung ausgeübt, was über die Zeit zu einer sicheren Klebeverbindung führt. Die beiden streifenförmigen Klebeschichten sind bevorzugt unterschiedlich ausgerüstet. Sie sind so ausgerüstet, dass sie sich magnetisch anziehen. Eine Klebeschicht kann beispielsweise mit einem permanent magnetischen Magnetpulver versetzt werden. Dieses kann dem zähflüssig aufbringbaren Kleber beigemischt sein. Der anderen Klebeschicht kann ein ferromagnetisches Pulver beigemischt sein, so dass sich die beiden Schichten magnetisch anziehen. Es ist aber auch möglich, dass die Materialien getrennt voneinander auf den jeweiligen Randbereich des Flächengebildes aufgebracht werden. So kann in einer ersten Schicht das jeweilige permanentmagnetische oder ferromagnetische Pulver auf den Randbereich des Flächengebildes aufgebracht werden. Über diese erste Schicht kann dann die lediglich aus einem Klebstoff bestehende Schicht aufgebracht werden. Als Klebstoffschicht kommen bei beiden Varianten die gängigen Materialien in Betracht, die in der Lage sind, Adhäsionskräfte oder Kohäsionskräfte aufeinander auszuüben. Insbesondere werden solche Klebstoffe verwendet, die sich bei Berührung aktivieren und Adhäsionskräfte ausüben. Der Klebstoff kann insbesondere klebende Kunststoff- oder Gummikomponenten enthalten, deren Zusammenwirkung eine Klebewirkung entfaltet. Die Folie kann einen mehrschichtigen Aufbau besitzen und ein Vlies aufweisen. Insbesondere besitzt die Folie eine Vlieslage und eine wassersperrende Folienlage. Die Klebeschichten können auch aus einem hotmelt-Material bestehen. Sie können aus demselben Material bestehen oder aber auch aus verschiedenen Materialien, die erst bei einem Inkontaktbringen eine Klebewirkung untereinander entfalten. Es ist insbesondere vorgesehen, dass lediglich eine Klebeschicht von Hause aus oberflächenklebrig ist und die jeweils andere Schicht nicht klebrig. Diese kann als Polymerschicht, Primer, Folie oder Ähnliches gestaltet sein. Damit die Klebeschichten ihre magnetischen Eigenschaften erhalten, kann die Klebeschicht aus einem ersten, nicht klebenden Streifen bestehen, der lediglich die magnetischen Eigenschaften aufweist. Auf diesen Streifen ist dann die eigentliche Klebeschicht geklebt. Zumindest eine Klebeschicht wird von einem passiven Abdeckstreifen abgedeckt. Bevorzugt werden beide Klebeschichten von einem derartigen Abdeckstreifen abgedeckt.The problem is solved by the fact that the edge areas are not only glued together. The edge regions are additionally magnetically equipped in such a way that the overlapping edge regions are attracted by a magnetic attraction force from a spacer layer into a contact position, in which the magnetic force increasing as the distance decreases exerts an initial pressure which achieves an initial adhesion to the adhesive connection, to which either one of the two adhesive layers with a ferromagnetic Metal powder, in particular iron powder added and the other adhesive layer is mixed with a permanent magnetic powder, or an edge region has a strip of a magnetic material and the other edge region with a strip of ferromagnetic material. According to this embodiment, the force required for the contact or the contact pressure is not exerted by the external pressure but by the magnetic attraction of the two adhesive layers. The attraction has a range that is sufficiently large to attract two slightly superimposed, unconnected adhesive layers from a distance of a few millimeters to a contact position. As the magnetic attraction increases as the distance between the two adhesive layers decreases, it not only exerts a force to pull film portions in a region between two rafters to a touch position. When between two rafters freely sagging underlays often occurs due to the different sags of the underlays in the overlap region a gap that must be sealed to prevent Zugluftbedingten heat loss. A significant advantage of the underlay sheet according to the invention is that the formation of such a gap due to the attractive force of the two edge regions is avoided from the outset. The magnetic force is also able to exert an initial pressure on the adhesive joint, so that the required initial adhesion is achieved. The magnetic forces exert a permanent slight pressure on the connection, resulting in a secure adhesive connection over time. The two strip-shaped adhesive layers are preferably equipped differently. They are equipped to attract themselves magnetically. An adhesive layer can be mixed, for example, with a permanent magnetic magnetic powder. This may be added to the viscous coatable adhesive. The other adhesive layer may be mixed with a ferromagnetic powder so that the two layers attract each other magnetically. But it is also possible that the materials are applied separately from each other on the respective edge region of the sheet. Thus, in a first layer, the respective permanent magnetic or ferromagnetic powder can be applied to the edge region of the fabric. About this first layer can then be applied only consisting of an adhesive layer. As an adhesive layer come in both variants, the common materials into consideration, which are able to exert adhesion forces or cohesive forces on each other. In particular, such adhesives are used which activate when touched and exert adhesive forces. The adhesive may in particular contain adhesive plastic or rubber components, the interaction of which unfolds an adhesive effect. The film may have a multilayer structure and have a nonwoven. In particular, the film has a nonwoven layer and a water-barrier film layer. The adhesive layers can also consist of a hotmelt material. They can consist of the same material or else of different materials, which unfold an adhesive effect only when contacting. In particular, it is provided that only one adhesive layer is tacky from the surface and the other layer is not tacky. This may be designed as a polymer layer, primer, film or the like. In order for the adhesive layers to obtain their magnetic properties, the adhesive layer can consist of a first, non-adhesive strip which has only the magnetic properties. On this strip then the actual adhesive layer is glued. At least one adhesive layer is covered by a passive cover strip. Both adhesive layers are preferably covered by such a cover strip.
Die Erfindung betrifft darüber hinaus auch eine Dachunterspannbahn, bei der lediglich ein Randbereich eine selbstklebende Klebeschicht aufweist. Diese kann mit einem Abdeckstreifen abgedeckt sein. Der andere Randbereich besitzt lediglich eine Klebekontaktfläche, die eine derartige Oberflächenbeschaffenheit aufweist, dass die Klebeschicht mit dieser Klebekontaktfläche eine klebende Verbindung eingehen kann. Die Klebekontaktfläche wird bevorzugt von einem Polymer ausgebildet. Ein derartiger Polymerstreifen ist fest mit dem Randbereich verbunden. Das Polymer kann auflackiert, aufgeschweißt oder aufgeklebt werden. Diese Art der Verklebung ist insbesondere bei Dachunterspannbahnen vorgesehen, die eine Vliesoberfläche aufweisen. Die Klebekontaktfläche besitzt eine größere Breite als die Klebeschicht des anderen Randbereichs, so dass sichergestellt ist, dass im Überlappungsbereich immer eine ordnungsgemäße Verklebung stattfindet.The invention also relates to a roof underlay, in which only one edge region has a self-adhesive layer. This can be covered with a cover strip. The other edge area has merely an adhesive contact surface which has such a surface finish that the adhesive layer can make an adhesive connection with this adhesive contact surface. The adhesive contact surface is preferably formed by a polymer. Such a polymer strip is firmly connected to the edge region. The polymer can be painted, welded or glued. This type of bonding is particularly provided in roof underlays, which have a nonwoven surface. The adhesive contact surface has a greater width than the adhesive layer of the other edge region, so that it is ensured that in the overlap region always takes place a proper bonding.

Der andere Randbereich 1" ist mit einem Magnetstreifen 5 versehen. Dieser ist im Ausführungsbeispiel in die Dachunterspannbahn 1 eingelassen. Die Dachunterspannbahn 1 besteht hier aus mehreren Schichten, so dass oberhalb und unterhalb des Magnetstreifens 5 bzw. des Metallstreifens 6 eine Schicht der Dachunterspannbahn 1 liegt. Der Randbereich 1" trägt auch eine Klebeschicht 2, die mit einem Abdeckstreifen 4 abgedeckt wird. Werden die beiden Abdeckstreifen 4 abgezogen, so können die beiden Klebeschichten 2 unmittelbar aneinander haften.

Die zuvor genannten Abdeckstreifen 4 dienen nicht nur dazu, eine Verschmutzung der Klebefläche zwischen Herstellung der Dachunterspannbahn und Verlegen derselben zu verhindern. Die Abdeckstreifen 4 werden in der Regel erst unmittelbar vor dem Verkleben bereits verlegter Bahnen abgezogen. Primär sollen die Abdeckstreifen 4 daher verhindern, dass die beiden Klebeschichten ungewollt in nicht ordnungsgemäßer Weise miteinander verkleben. Derartige Abdeckstreifen, die das gegenseitige Verkleben von Klebeschichten verhindern, werden auch als Releasefolie bezeichnet.The aforementioned cover strips 4 are not only intended to prevent contamination of the adhesive surface between production of the roof underlay sheet and laying the same. The cover strips 4 are usually deducted only immediately before the bonding already laid paths. Primarily, the cover strips 4 should therefore prevent the two adhesive layers from unintentionally sticking together in an improper manner. Such cover strips, which prevent the mutual bonding of adhesive layers, are also referred to as release film.
