Description

Die Erfindung betrifft eine Vorrichtung zum Zuschneiden von Dämmmaterial, insbesondere Mineralfaserdämmstoffbahnen und/oder Mineralfaserdämmstoffplatten.The invention relates to a device for cutting insulation material, in particular mineral fiber insulation webs and / or mineral fiber insulation material panels.

Aus dem Stand der Technik ist es bekannt, dass von Mineralfaserdämmstoffbahnen Abschnitte abgetrennt werden müssen, die den Maßen eines Einbauraumes, beispielsweise in einem Sparrenfeld entsprechen müssen. In gleicher Weise werden Mineralfaserdämmstoffplatten zugeschnitten, wobei in der Regel ein Schneidmesser verwendet wird, welches auf einer großen Oberfläche der Mineralfaserdämmstoffbahn bzw. der Mineralfaserdämmstoffplatte angesetzt und beispielsweise entlang einer zuvor festgelegten und gegebenenfalls angezeichneten Linie durch die Mineralfaserdämmstoffbahn bzw. die Mineralfaserdämmstoffplatte gezogen wird. Bei dieser Vorgehensweise wird die Mineralfaserdämmstoffbahn bzw. die Mineralfaserdämmstoffplatte auf einem Untergrund, in der Regel dem Boden aufgelegt und von der den Schnitt ausführenden Person mit der Hand oder dem Fuß festgehalten. Bei relativ dünnen Mineralfaserdämmstoffbahnen und/oder Minerafaserdämmstoffplatten hat sich diese Vorgehensweise grundsätzlich bewährt, da hierzu nur wenige Werkzeuge, wie Messer und/oder Lineal notwendig sind. Mit zunehmender Materialstärke der Mineralfaserdämmstoffbahn sowie mit zunehmender Rohdichte dieser Dämmstoffe wird das voranstehend beschriebene Zuschneiden dieser Mineralfaserdämmstoffbahnen bzw. Mineralfaserdämmstoffplatten erschwert, da die Führung des Messers in der Regel quer zum Faserverlauf aufgrund der voranstehend genannten Materialeigenschaften erschwert wird. Es sind dann mit unter zwei oder mehr nacheinander auszuführende Schnitte in der gleichen Schnittebene durchzuführen. Die hierbei ausgeführte Handarbeit führt aber zu ungenauen Schnitten, die dann das Dämmergebnis beispielsweise in einem Sparrenfeld zwischen benachbarten Dachsparren erheblich verschlechtern können, da aufgrund ungenauer, dass heißt nicht gerader Schnitte ein vollständiges Anliegen des abgelängten Mineralfaserdämmstoffes an den Sparren nicht immer gewährleistet ist.It is known from the prior art that sections must be separated from mineral fiber insulation webs which must correspond to the dimensions of an installation space, for example in a rafter field. In the same way, mineral fiber insulation boards are cut, whereby a cutting knife is generally used, which is applied to a large surface of the mineral fiber insulation web or mineral fiber insulation board and, for example, is drawn through the mineral fiber insulation web or mineral fiber insulation board along a predetermined and possibly marked line. With this procedure, the mineral fiber insulation sheet or the mineral fiber insulation sheet is placed on a surface, usually the floor, and held by the person performing the cut with his hand or foot. In the case of relatively thin mineral fiber insulation webs and / or mineral fiber insulation panels, this procedure has proven itself in principle, since only a few tools, such as knives and / or rulers, are required for this. With increasing material thickness of the mineral fiber insulating material web and with increasing bulk density of these insulating materials, the above-described cutting of these mineral fiber insulating material webs or mineral fiber insulating material boards becomes more difficult, since guiding the knife across the fiber course is generally made more difficult due to the material properties mentioned above. It is then to be performed with less than two or more cuts in succession in the same cutting plane. However, the manual work carried out here leads to inaccurate cuts, which can then considerably deteriorate the insulation result, for example in a rafter field between adjacent rafters, since due to imprecise, that is to say not straight cuts, a complete concern of the cut mineral fiber insulation on the rafters is not always guaranteed.

Aus der DE 195 13 984 A1 ist bereits eine Trennvorrichtung zum Herstellen aus z. B. Glaswolle bestehenden Dämmplatten bekannt. Diese vorbekannte Vorrichtung besteht aus einem Auflagebalken und einer einseitig angeordneten Halterung, in der ein Spannbalken in verschiedenen Abständen zum Auflagebalken verschwenkbar gelagert werden kann. An dem der Halterung gegenüberliegenden Ende weist der Auflagebalken zwei Führungsleisten mit Rasthaken auf, die der Verspannung des Spannbalkens bei eingelegtem Dämmmaterial dient. Bei dieser vorbekannten Vorrichtung ist es nachteilig, dass der Spannbalken lediglich um einen Drehpunkt relativ zum Auflagebalken verschwenkbar ist. Für unterschiedliche Materialstärken des Dämmmaterials muß diese Vorrichtung eingestellt werden, um eine sichere Spannfunktion zu gewährleisten.DE 195 13 984 A1 has already disclosed a separating device for producing z. B. glass wool existing insulation boards known. This previously known device consists of a support beam and a bracket arranged on one side, in which a clamping beam can be pivotably mounted at different distances from the support beam. At the end opposite the bracket, the support bar has two guide strips with latching hooks, which serve to brace the tensioning bar when the insulating material is inserted. In this known device, it is disadvantageous that the clamping bar can only be pivoted about a pivot point relative to the support bar. This device must be set for different material thicknesses of the insulating material in order to ensure a secure tensioning function.

Ausgehend von diesem Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine Vorrichtung zum Zuschneiden von Dämmstoffmaterial zu schaffen, die in einfacher und kostengünstiger Weise herstellbar und darüberhinaus in einfacher Weise anwendbar ist.Starting from this prior art, the invention is therefore based on the object of providing a device for cutting insulation material which can be produced in a simple and inexpensive manner and, moreover, can be used in a simple manner.

Die Lösung dieser Aufgabenstellung sieht eine gattungsgemäße Vorrichtung, bestehend aus einem Auflagekörper und einem am Auflagekörper beweglich angeordneten Klemmelement vor, zwischen denen das Dämmstoffmaterial klemmend angeordnet wird, wobei Auflagekörper und Klemmelement eine quaderf örmige Ausgestaltung mit einer hinsichtlich zumindest ihrer Länge sehr geringen Dicke aufweisen, der Auflagekörper zumindest eine geradlinige Schneidkante aufweist und das Klemmelement entlang von Führungselementen hin zum Auflagekörper parallel bewegbar ist.The solution to this problem is provided by a generic device consisting of a support body and a clamping element movably arranged on the support body, between which the insulating material is arranged in a clamping manner, wherein the support body and the clamping element have a cuboid configuration with a thickness that is at least very small in terms of length Support body has at least one rectilinear cutting edge and the clamping element is movable parallel to the support body along guide elements.

Bei der erfindungsgemäßen Vorrichtung kann ein Dämmstoffmaterial, insbesondere eine Mineralfaserdämmstoffbahn und/oder Mineralfaserdämmstoffplatte zwischen dem Auflagekörper und dem Klemmelement derart angeordnet werden, dass die abzuschneidende Länge des Dämmstoffmaterials über die Schneidkante des Auflagekörpers herausragt. Durch die Bewegbarkeit des Klemmelementes besteht die Möglichkeit, das Klemmelement in Richtung auf den Auflagekörper zu bewegen und das Dämmstoffmaterial kraftschlüssig in der Vorrichtung zu fixieren. Hierbei wird das Dämmstoffmaterial komprimiert. Anschließend besteht die Möglichkeit, dass das Dämmstoffmaterial entlang der Schneidkante mit dem ansich bekannten Schneidmesser abzuschneiden, wobei der Schnitt auch bei Dämmstoffmaterialien mit hoher Rohdichte bzw. größerer Materialstärke aufgrund der vorherigen Kompression in der Regel in einem Schnitt durchgeführt werden kann. Hieraus ergeben sich geradlinige Schnittkanten, die den Einbau des abgelängten Dämmstoffmaterials wesentlich vereinfachen und hinsichtlich eines ordnungsgemäßen Einbaus wesentlich sicherer machen.In the device according to the invention, an insulation material, in particular a mineral fiber insulation sheet and / or mineral fiber insulation plate, can be arranged between the support body and the clamping element in such a way that the length of the insulation material to be cut protrudes beyond the cutting edge of the support body. The movability of the clamping element makes it possible to move the clamping element in the direction of the support body and to fix the insulation material in the device in a force-locking manner. This compresses the insulation material. There is then the possibility that the insulation material is cut off along the cutting edge with the cutting knife known per se, the cut also being able to be carried out in one cut as a rule with insulation material with a high bulk density or greater material thickness due to the previous compression. This results in straight cut edges that considerably simplify the installation of the cut insulation material and make it much safer with regard to proper installation.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Führungselemente schienenförmig ausgebildet und im Bereich der Enden des Auflagekörpers angeordnet sind. Durch die schienenförmige Ausführung der Führungselemente ist eine exakte Führung des Klemmelementes während der Bewegung zum Auflagekörper hin oder vom Auflagekörper weg möglich.According to a further feature of the invention, it is provided that the guide elements are of rail-shaped design and are arranged in the region of the ends of the support body. Due to the rail-shaped design of the guide elements, an exact guidance of the clamping element is possible during the movement towards the support body or away from the support body.

Vorzugsweise ist vorgesehen, dass die Führungselemente als runde Profilabschnitte ausgebildet sind, von denen an jedem Ende des Auflagekörpers zwei im Abstand zueinander angeordnet sind, die fest mit dem Auflagekörper verbunden sind, insbesondere verschraubt und/oder verklebt sind und sich durch korrespondierende Bohrungen im Klemmelement erstrecken. Bei dieser Ausgestaltung steht insbesondere der Vorteil im Vordergrund, dass eine derartige Ausgestaltung sehr kostengünstig herstellbar ist und gleichzeitig sehr gute Führungseigenschaften für die Bewegung des Klemmelementes relativ zum Auflagekörper bereitstellt.It is preferably provided that the guide elements are designed as round profile sections, two of which are arranged at a distance from one another at each end of the support body, which are fixedly connected to the support body, in particular are screwed and / or glued and extend through corresponding bores in the clamping element , In this embodiment, the main focus is on the advantage that such an embodiment can be produced very inexpensively and at the same time provides very good guiding properties for the movement of the clamping element relative to the support body.

Zwischen dem Klemmelement und dem Auflagekörper ist zumindest ein Kraftspeicher, insbesondere in Form von Druckfedern angeordnet, die bei einer Bewegung des Klemmelements zum Auflagekörper hin gespannt werden. Die Druckfedern sorgen demzufolge dafür, dass das Klemmelement im Ausgangszustand im Abstand zum Auflagekörper angeordnet ist, um das Einschieben des Dämmstoffmaterials zwischen Auflagekörper und Klemmelement zu erleichtern. Ist das Dämmstoffmaterial in gewünschter Länge zwischen dem Klemmelement und dem Auflagekörper angeordnet, so kann das Klemmelement entgegen der Federkraft in Richtung auf den Auflagekörper gedrückt werden. Hierzu bedient sich die handhabende Person beispielsweise eines Fußes, mit dem sie das Klemmelement in Richtung auf den Auflagekörper niederdrückt. Anschließend kann dann der Schnitt rechtwinklig zu den Längskanten des Dämmstoffmaterials durchgeführt werden.At least one energy accumulator, in particular in the form of compression springs, is arranged between the clamping element and the support body and is tensioned when the clamping element moves toward the support body. The compression springs consequently ensure that, in the initial state, the clamping element is arranged at a distance from the support body in order to facilitate the insertion of the insulating material between the support body and the clamping element. If the insulating material is arranged in the desired length between the clamping element and the support body, the clamping element can be pressed against the spring force in the direction of the support body. For this purpose, the handling person uses, for example, a foot with which he presses the clamping element in the direction of the support body. The cut can then be carried out at right angles to the longitudinal edges of the insulation material.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass das Klemmelement eine Breite aufweist, die eine Fußbetätigung des Klemmelements ermöglicht.According to a further feature of the invention, it is provided that the clamping element has a width that enables foot actuation of the clamping element.

Es ist ferner vorgesehen, dass das Klemmelement eine Breite aufweist, die geringer als die Breite des Auflagekörpers ist und dass das Klemmelement mittig über dem Auflagekörper angeordnet ist. Bei dieser Ausgestaltung ist es für die handhabenden Personen in einfacher Weise optisch erkennbar, ob das abzuhängende Dämmstoffmaterial an der vorgesehenen Stelle in Übereinstimmung mit der Schneidkante am Auflagekörper angeordnet ist, bevor der Trennschnitt durchgeführt wird.It is further provided that the clamping element has a width that is less than the width of the support body and that the clamping element is arranged centrally above the support body. In this embodiment, it is easy for the handling person to visually recognize whether the insulation material to be suspended is arranged at the intended location in accordance with the cutting edge on the support body before the separating cut is carried out.

Das Klemmelement und/oder der Auflagekörper ist vorzugsweise aus Metall, insbesondere Aluminium und/oder Holz ausgebildet. Diese Materialien gewährleisten eine kostengünstige Herstellung bei gleichzeitig langer Lebensdauer. Eine derartige Vorrichtung ist darüber hinaus ausreichend robust, so dass die Vorrichtung auch den rauhen Bedingungen auf Baustellen widerstehen kann.The clamping element and / or the support body is preferably made of metal, in particular aluminum and / or wood. These materials ensure cost-effective production with a long service life. Such a device is also sufficiently robust so that the device can withstand the harsh conditions on construction sites.

Die Schneidkante ist im Querschnitt als L-förmiges Profil ausgebildet und am Auflagekörper befestigt. Über die Schneidkante wird somit der Auflagekörper dahingehend geschützt, dass ein unsauber ausgeführter Schnitt nicht in den Auflagekörper einschneiden kann. Zu diesem Zweck hat es sich als vorteilhaft erwiesen, die Schneidkante aus Metall, beispielsweise Aluminium auszubilden.The cutting edge is designed in cross section as an L-shaped profile and fastened to the support body. The support body is thus protected over the cutting edge in such a way that an improperly executed cut cannot cut into the support body. For this purpose, it has proven to be advantageous to form the cutting edge from metal, for example aluminum.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Schneidkante eine Schnittleiste mit einer V-förmigen Nut für die Führung eines Schneidwerkzeuges aufweist, wobei die Schnittleiste mit dem Auflagekörper verschraubt ist. Die V-förmige Nut dient der Führung des Schneidmessers, um der handhabenden Person eine Hilfestellung zur Ausführung gerader Schnitte zu bieten. Durch das Verschrauben der Schnittleiste am Auflagekörper besteht die Möglichkeit, die Schnittleiste bei Verschleiß in einfacher Weise auszuwechseln, ohne dass die Funktionsweise bzw. Brauchbarkeit der erfindungsgemäßen Vorrichtung beeinträchtigt ist.According to a further feature of the invention, it is provided that the cutting edge has a cutting bar with a V-shaped groove for guiding a cutting tool, the cutting bar being screwed to the support body. The V-shaped groove is used to guide the cutting knife in order to provide the operator with assistance in making straight cuts. By screwing the cutting bar to the support body, there is the possibility of replacing the cutting bar in a simple manner when it is worn, without the functionality or usability of the device according to the invention being impaired.

Der Auflagekörper weist zumindest eine quer zur seiner Längserstreckung verlaufende, vorzugsweise an der Unterseite des Auflagekörpers angeordnete Öffnung auf, in die ein Schenkel eines Anschlagwinkels verschiebbar einsetzbar ist. Über diesen Anschlagwinkel kann eine zuvor abgemessene Länge des Einbauraumes fest eingestellt werden, so dass nachfolgendes Zuschneiden der notwendigen Anzahl von Abschnitten des Dämmstoffmaterials vereinfacht und damit beschleunigt ist. Es besteht für die handhabende Person mit diesem Anschlagwinkel die Möglichkeit, eine Vielzahl von längenmäßig exakt gleichen Abschnitten in einfacher und schneller Weise herzustellen.The support body has at least one opening which runs transversely to its longitudinal extension and is preferably arranged on the underside of the support body and into which one leg of a stop angle can be inserted. A previously measured length of the installation space can be permanently set via this stop angle, so that subsequent cutting of the necessary number of sections of the insulation material is simplified and thus accelerated. With this stop angle, the handling person has the possibility of producing a large number of sections of exactly the same length in a simple and quick manner.

Vorzugsweise ist die Öffnung für den Anschlagwinkel außerhalb , insbesondere unterhalb des durch die Führungselemente begrenzten Schneidbereichs des Auflagekörpers angeordnet, so dass der Anschlagwinkel nicht im Bereich des schneidenden Messers liegt.The opening for the stop angle is preferably outside, in particular below, the cutting area of the Support body arranged so that the stop angle is not in the area of the cutting knife.

Der Anschlagwinkel ist insbesondere U-förmig ausgebildet und kann alternativ zwei in Öffnungen geführte Schenkel, sowie einen die beiden Schenkel verbindenden Steg auf, wobei der Steg als Anschlag ausgebildet und parallel zur Schneidkante verlaufend angeordnet ist. Bei dieser Ausgestaltung hat es sich als vorteilhaft erwiesen, dass die parallele Führung des Anschlags zur Schneidkante exakt eingehalten wird. Der Anschlag steht hierbei über die Oberfläche der beiden Schenkeln nach oben hervor, so dass das Dämmstoffmaterial auf den Schenkel aufliegend bis an den Anschlag geführt werden kann, an welchen das Dämmstoffmaterial bündig anschließt.The stop angle is in particular U-shaped and can alternatively have two legs guided into openings and a web connecting the two legs, the web being designed as a stop and arranged parallel to the cutting edge. In this configuration, it has proven to be advantageous that the parallel guidance of the stop to the cutting edge is observed exactly. The stop protrudes upwards above the surface of the two legs, so that the insulation material lying on the leg can be guided up to the stop, to which the insulation material is flush.

Ergänzend kann der Steg des Anschlagwinkels eine Längenskalierung aufweisen, die es der handhabenden Person vereinfacht, die zuvor beispielsweise zwischen den Sparren gemessene Länge in der erfindungsgemäßen Vorrichtung einzustellen.In addition, the web of the stop angle can have a length scale, which makes it easier for the handling person to set the length previously measured, for example, between the rafters in the device according to the invention.

Schließlich ist bei der erfindungsgemäßen Vorrichtung vorgesehen, dass das Klemmelement am Auflagekörper schamiert ist, so dass das Klemmelemnt aus einer parallelen Anordnung zum Auflagekörper in eine annähernd rechtwinklige Anordnung zum Auflagekörper überführbar ist. Durch ein Scharnier zwischen dem Klemmelement und dem Auflagekörper wird die Handhabung der erfindungsgemäßen Vorrichtung wesentlich vereinfacht, da das Dämmstoffmaterial dann zwischen Klemmelement und Auflagekörper eingelegt werden kann. Auf ein Einschieben zwischen die beiden Konstruktionselemente kann daher verzichtet werden. Dieser Vorteil wird insbesondere bei Dämmstoffmaterial mit hoher Rohdichte bzw. großer Materialstärke evident, da bei diesen Dämmstoffmaterialien ein Schieben zwischen zwei einander gegenüberliegend angeordneten Konstruktionselementen nur mit großem Kraftaufwand möglich ist.Finally, it is provided in the device according to the invention that the clamping element on the support body is covered with shear so that the clamping element can be transferred from a parallel arrangement to the support body into an approximately rectangular arrangement to the support body. A hinge between the clamping element and the support body considerably simplifies the handling of the device according to the invention, since the insulation material can then be inserted between the clamping element and the support body. An insertion between the two construction elements can therefore be dispensed with. This advantage is particularly evident in the case of insulating material with a high bulk density or high material thickness, since with these insulating materials it is only possible to push between two construction elements arranged opposite one another with great effort.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung der dazugehörigen Zeichnung, in der eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung in perspektivischer Ansicht dargestellt ist.Further features and advantages of the invention result from the following description of the associated drawing, in which a preferred embodiment of the device according to the invention is shown in a perspective view.

Die in der Figur dargestellte Vorrichtung zum Zuschneiden von Dämmstoffmaterial, insbesondere Mineralfaserdämmstofbahnen und/oder Mineralfaserdämmstoffplatten besteht aus einem Auflagekörper 1 und einem am Auflagekörper 1 beweglich angeordneten Klemmelement 2. Auflagekörper 1 und Klemmelement 2 sind plattenförmig ausgebildet.The device shown in the figure for cutting insulation material, in particular mineral fiber insulation sheets and / or mineral fiber insulation panels, consists of a support body 1 and a clamping element 2 movably arranged on the support body 1. Support body 1 and clamping element 2 are plate-shaped.

Im Bereich seiner beiden Enden weist der Auflagekörper 1 jeweils zwei als im Querschnitt runde Profilabschnitte ausgebildete Führungselemente 3 auf, die parallel zur Schmalseite des Auflagekörpers 1 im Abstand zueinander angeordnet sind. Die Führungselemente 3 durchgreifen korrespondierende Bohrungen im Klemmelement 2, so dass das Klemmelement 2 entlang der Führungselemente 3 relativ zum Auflagekörper 1 bewegbar ist. Die Führungselemente 3 sind fest mit dem Auflagekörper 1 verbunden. Beispielsweise können die Führungselemente 3 in den Auflagekörper 1 eingeschraubt und/oder mit dem Auflagekörper 1 verklebt sein.In the area of its two ends, the support body 1 each has two guide elements 3, which are designed as profile sections that are round in cross section and are arranged parallel to the narrow side of the support body 1 at a distance from one another. The guide elements 3 pass through corresponding bores in the clamping element 2, so that the clamping element 2 can be moved along the guide elements 3 relative to the support body 1. The guide elements 3 are firmly connected to the support body 1. For example, the guide elements 3 can be screwed into the support body 1 and / or glued to the support body 1.

Zwischen dem Auflagekörper 1 und dem Klemmelement 2 ist im Bereich eines jeden Führungselementes 3 eine Druckfeder 4 angeordnet, die das Klemmelement 2 im Abstand zum Auflagekörper 1 halten, so dass zwischen dem Auflagekörper 1 und dem Klemmelement 2 ein Raum angeordnet ist, in dem das nicht näherdargestellte Dämmstoffmaterial einschiebbar ist. Die Führungselemente 3 können an ihren freien Enden darüber hinaus nicht dargestellte Feststeller aufweisen, die das Klemmelement 2 am Auflagekörper 1 sichern.Between the support body 1 and the clamping element 2, a compression spring 4 is arranged in the region of each guide element 3, which hold the clamping element 2 at a distance from the support body 1, so that a space is arranged between the support body 1 and the clamping element 2 in which this is not insulation material shown can be inserted. At their free ends, the guide elements 3 can also have locking devices, not shown, which secure the clamping element 2 on the support body 1.

Der Auflagekörper 1 weist ferner eine Schneidkante 5 auf, die sich entlang einer Längsseite des Auflagekörpers 1 erstreckt. Die Schneidkante 5 ist Bestandteil einer Schnittleiste, die eine V-förmige Nut für die Führung eines Schneidwerkzeugs aufweist, wobei die Schnittleiste mit dem Auflagekörper 1 verschraubt ist.The support body 1 also has a cutting edge 5 which extends along a long side of the support body 1. The cutting edge 5 is part of a cutting bar, which has a V-shaped groove for guiding a Has cutting tool, the cutting bar is screwed to the support body 1.

Schließlich weist die Vorrichtung einen Anschlagwinkel 6 auf, der aus einem Schenkel 7 und einem Anschlagelement 8 besteht, welches rechtwinklig zum Schenkel 7 angeordnet ist. Der Schenkel 7 ist in einer im Auflagekörper 1 quer zur seiner Längserstreckung verlaufenden Öffnung 9 unterhalb des Auflagekörpers 1 verschiebbar geführt.Finally, the device has a stop angle 6, which consists of a leg 7 and a stop element 8, which is arranged at right angles to the leg 7. The leg 7 is slidably guided in an opening 9 in the support body 1 which extends transversely to its longitudinal extent below the support body 1.

Auf seiner Oberfläche 10 weist der Schenkel 7 ergänzend eine Längenskalierung 11 auf. Der Anschlagwinkel 8 kann form- oder reibschlüssig im Auflagekörper 1 arretiert werden, um einen eingestellten Abstand zwischen der Schneidkante 5 und dem Anschlagwinkel 8 festzusetzen.The leg 7 additionally has a length scaling 11 on its surface 10. The stop angle 8 can be locked in a form-fitting or frictional manner in the support body 1 in order to fix a set distance between the cutting edge 5 and the stop angle 8.

Die Handhabung der voranstehend beschriebenen Vorrichtung ist wie folgt: Zwischen Auflagekörper 1 und Führungselement 3 wird eine Mineralfaserdämmstoffbahn soweit eingeschoben, bis die vordere Schmalseite der Mineralfaserdämmstoffbahn an der Anschlagfläche 8 anliegt. Die Anschlagfläche 8 ist zuvor entsprechend der Längenskalierung 11 in einem gewünschten Abstand zur Schneidkante 5 eingestellt worden.The handling of the device described above is as follows: A mineral fiber insulating material sheet is inserted between the support body 1 and the guide element 3 until the front narrow side of the mineral fiber insulating material sheet abuts the stop surface 8. The stop surface 8 has previously been set according to the length scaling 11 at a desired distance from the cutting edge 5.

Sobald die Mineralfaserdämmstoffbahn die gewünschte Lage in der Vorrichtung eingenommen hat, wird das Klemmelement 2 entgegen der Federkraft der Druckfedern 4 in Richtung auf den Auflagekörper 1 verschoben. Hierzu kann die handhabende Person beispielsweise einen Fuß auf das Klemmelement 2 aufsetzen und das Klemmelement 2 in Richtung auf den Auflagekörper 1 niederdrücken. Hierbei wird die Mineralfaserdämmstoffbahn sehr stark komprimiert und reibschlüssig in der Vorrichtung gehalten. Anschließend wird die Mineralfaserdämmstoffbahn mit einem Schneidmesser parallel zur Schneidkante 5 geschnitten. Hierbei dient die Schneidkante 5 bzw. eine ergänzend vorgesehenes V-förmige Nut der Führung des Schneidmessers, um einen geradlinigen Schnitt durchzuführen. Bei einem Dämmstoffmaterial mit sehr hoher Rohdichte kann es erforderlich sein, zwei Schnitte mit dem Schneidmesser durchzuführen, wobei jeder Schnitt einen Teil der Materialstärke durchtrennt.As soon as the mineral fiber insulating material web has assumed the desired position in the device, the clamping element 2 is displaced against the spring force of the compression springs 4 in the direction of the support body 1. For this purpose, the handling person can place a foot on the clamping element 2 and press the clamping element 2 in the direction of the support body 1, for example. The mineral fiber insulation web is compressed very strongly and held in the device by friction. Then the mineral fiber insulation web is cut parallel to the cutting edge 5 with a cutting knife. Here, the cutting edge 5 or an additional V-shaped groove is used to guide the cutting knife in order to carry out a straight cut. With an insulation material with a very high bulk density, it can it may be necessary to make two cuts with the cutting knife, each cut cutting through part of the material thickness.

Nach der Herausnahme des derart abgetrennten Abschnittes der Mineralfaserdämmstoffbahn wird die Mineralfaserdämmstoffbahn wieder bis zur Anlage an der Anschlagfläche 8 vorgeschoben, bevor ein weiterer Schnitt durchgeführt wird. Auf diese Weise kann die Mineralfaserdämmstoffbahn in gleiche Abschnitte abgelängt werden, die dann für den bestimmungsgemäßen Einbau zur Verfügung stehen.After removal of the section of the mineral fiber insulating material web separated in this way, the mineral fiber insulating material web is pushed back up to the abutment surface 8 before a further cut is carried out. In this way, the mineral fiber insulation web can be cut to length in the same sections, which are then available for the intended installation.
