Abstract

The invention relates to a cutting device, as well as to the use of a cutting device, comprising a cutting blade (10) which is pivotably fixed to a stand (1), the cutting edge (12) of said cutting blade (10) descending into an entry slot (6) between two supporting members (2) during the cutting process in order to press out a strip of material (91) from a panel-shaped workpiece (9) placed on the supporting members (2). The width of the entry slot (6) is adjusted to the material thickness of the cutting blade (10) in such a way that, when the cutting blade (10) is positioned in the centre of the entry slot (6), a gap remains, at least in the region of the cutting edge (12), between each of the two supporting member edges (4') or slot walls (4) and the broad faces (11) of the cutting blade (10), said broad faces (11) lying opposite the supporting member edges (4') or slot walls (4). In order for panels or tiles, in particular floor coverings or roof shingles consisting of synthetic material, rubber or of another tough or elastic material to be cut with sufficiently high cutting quality on the cutting device, it is proposed that the gap (11, 4') measure no more than 0.7 mm for cutting panels or tiles between 1mm and 5mm thick, in particular floor coverings or roof shingles consisting of synthetic material, rubber or of another tough or elastic material.

Description

Schneidevorrichtung für Fußbodenbeläge, Dachschindeln oder dergleichen aus Kunststoff, Gummi oder einem anderen zähen oder elastischen Werkstoff Die Erfindung betrifft eine Schneidevorrichtung mit einem an einem Gestell schwenkbar befestigten Schneidmesser, dessen Schneidkante beim Schnitt in einen Eintauchschlitz zwischen zwei Tragholmen mit einem beidseitigen Spaltabstand zwischen Schneidmesserbreitseite und Tragholmkante eintaucht, um aus einem auf den Tragholmen aufliegenden plattenf örmigen Werkstück einen Materialstreifen herauszudrücken.  The invention relates to a cutting device with a pivotally mounted on a frame cutting blade, the cutting edge when cutting into a dip slot between two support beams with a two-sided gap distance between Schneidmesserbreitseite and Tragholmkante dips to push out a strip of material from a lying on the support bars plate-shaped workpiece.
Eine derartige Schneidevorrichtung wird von der DE 10 2009 003 490 AI beschrieben. Die Schneidevorrichtung besitzt ein Gestell, welches aus zwei parallel zueinander verlaufenden Tragholmen besteht, die an ihren beiden Enden mit Füßen verbunden sind. Zwischen den beiden Tragholmen erstreckt sich ein Eintauchschlitz. Ein zwischen den beiden Tragholmen schwenkbar gelagertes Schneidmesser, dessen Schneidkante Zähne aufweist, kann in den Eintauchschlitz eintauchen. Dabei verbleibt zwischen den Breitseiten des Schneidmessers und den Schlitzwänden des Eintauchschlitzes ein Spaltabstand. Auch ein frei etwas außermittig in den Schlitz eintauchendes Schneidmesser zentriert sich unter Schnittbelastung zur Folge einer Deformation des Werkstücks in den Schlitz, so dass der Spaltabstand auf beiden Seiten des Schneidmessers in etwa gleich ist. Such a cutting device is described by DE 10 2009 003 490 AI. The cutting device has a frame, which consists of two mutually parallel support beams, which are connected at both ends with feet. Between the two beams extends a dip slot. A pivotally mounted between the two support bars cutting blade whose cutting edge has teeth can dip into the immersion slot. It remains between the broad sides of the cutting blade and the slot walls of the immersion slot a gap distance. A cutting blade which dives freely into the slot somewhat eccentrically also centers itself under cutting load as a result of a deformation of the workpiece into the slot, so that the gap spacing on both sides of the cutting blade is approximately the same.
Schneidgeräte der vorbezeichneten Art sind ferner bekannt aus der FR 575749, der FR 612747 A und der FR 847014 A. Das eingangs genannte Schneidgerät ist für das Zerteilen von Laminatfußbodenplatten vorgesehen. Bei auf dem Markt befindlichen Schneidevorrichtungen für Laminatfußbodenplatten beträgt der Spaltabstand zwischen der Schneidmesserbreitseite und der Tragholmkante etwa 2mm bis 2,5mm. Ein derart großer Spalt ist erforderlich, um die Kräfte, die beim Herausdrücken eines Materialstreifens aus der Laminatfußbodenplatte in den Eintauchschlitz entstehen, gering zu halten. Auf dem Markt sind ferner Schneidegeräte zum Schneiden vom Laminatplatten bekannt, bei denen der Spaltabstand geringer als 2 mm ist und die einen unhandlich langen Griff am Schneidmesser aufweisen. Cutting devices of the type described above are also known from FR 575749, FR 612747 A and FR 847014 A. The aforementioned cutting device is provided for the cutting of laminate floor panels. For cutting devices on the market For laminate floor panels, the gap distance between the cutting blade width side and the beam edge is about 2mm to 2.5mm. Such a large gap is required in order to minimize the forces that arise when pushing out a strip of material from the laminate floor panel into the immersion slot. Also known in the market are cutting devices for cutting laminate boards where the gap distance is less than 2mm and which has a cumbersome long handle on the cutting blade.
Der Erfindung liegt die Aufgabe zugrunde, die Schneidevorrichtung dahingehend weiterzubilden, dass auf ihr Fußbodenbeläge oder andere Platten aus Kunststoff, Gummi oder einem anderen zähen oder elastischen Werkstoff mit ausreichend hoher Schnittqualität geschnitten werden können. The invention has the object of developing the cutting device to the effect that can be cut on her floor coverings or other plates made of plastic, rubber or other tough or elastic material with sufficiently high quality cut.
Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung. The object is achieved by the invention specified in the claims.
Es hat sich herausgestellt, dass die Schneidevorrichtungen des Standes der Technik zufolge des großen Spaltabstandes zwischen der Schneidmesserbreit- seite und der Tragholmkante zum Zerteilen von Platten, insbesondere von Fußbodenbelägen aus Kunststoff, beispielsweise Vinyl-Fußbodenfliesen ungeeignet sind. Die Schnittränder fransen bei der Verwendung der bekannten Schneidevorrichtung aus. Dies gilt nicht nur für Vinyl-Fußbodenbeläge mit einer geringen Materialstärke, beispielsweise 2,5mm, sondern auch für Vinylbeläge mit 5mm Materialstärke und erst recht für PVC-Fliesen, die lediglich 1,8mm stark sind. In Versuchsreihen hat sich herausgestellt, dass eine Reduzierung des Spaltabstandes zumindest im Bereich der Schneidkante auf Werte unter 2mm also insbesondere auf Werte zwischen 0,2mm bis 2mm zu deutlich verbesserten Ergebnissen führt. In Bereichen entfernt von der Schneidkante kann der Spalt- abstand größer sein. Insbesondere bei Vinylbelägen mit einer hohen Materialstärke führt eine Reduzierung des Spaltabstandes zwischen Schneidmesser- breitseite und Tragholmkante bzw. Schlitzwand auf Werte unter 2mm zu deutlich verbesserten Schnittrandqualitäten. Die Schnittrandqualität dünneren Materials kann noch verbessert werden, wenn der Spaltabstand auf 1,6 mm bzw. 1,4 mm begrenzt ist. Sehr dünne PVC-Fliesen lassen sich optimal schneiden, wenn der Spaltabstand etwas größer als 0,2mm ist. Allerdings sind die dabei aufzuwendenden Kräfte insbesondere bei Vinylfliesen mit etwas höherer Materialstärke recht hoch. Insofern ist es vorteilhafter, wenn der Spaltabstand in einem Bereich zwischen 0,5 mm und 0,9 mm liegt. Eine universelle Verwendbarkeit der Schneidevorrichtung ist dann gegeben, wenn der Spaltabstand etwa 0,7 mm beträgt. Dieser Wert ist toleranzbehaftet, wobei die Toleranzen relativ unkritisch sind. Es ist von besonderem Vorteil, wenn die Schneidkante mit einer Verzahnung versehen ist. Der Abstand der Zahnfirste liegt dabei in der Größenordnung der Materialstärke der zu schneidenden Beläge, also zwischen 1mm und 5mm. Bevorzugt ist der Abstand der Zahnfirste jedoch größer als 2mm. Die Zähne besitzen Zahnfirste, die sich parallel zur Drehachse desIt has been found that the cutting devices of the prior art due to the large gap distance between the Schneidmesserbreit- side and the carrier beam edge for dividing plates, in particular plastic floor coverings, such as vinyl floor tiles are unsuitable. The cut edges fray when using the known cutting device. This applies not only to vinyl floor coverings with a low material thickness, for example 2.5 mm, but also for vinyl floor coverings with 5mm material thickness and even more so for PVC tiles, which are only 1.8mm thick. In test series it has been found that a reduction of the gap distance, at least in the region of the cutting edge to values below 2 mm, in particular to values between 0.2 mm and 2 mm, leads to significantly improved results. In areas away from the cutting edge, the gap distance may be greater. Particularly in the case of vinyl coverings with a high material thickness, a reduction of the gap distance between cutting blade broad side and supporting beam edge or diaphragm wall to values below 2mm to significantly improved cutting edge qualities. The cut edge quality of thinner material can be further improved if the gap distance is limited to 1.6 mm or 1.4 mm. Very thin PVC tiles can be cut optimally if the gap distance is slightly larger than 0.2 mm. However, the forces to be expended are quite high, especially for vinyl tiles with a slightly higher material thickness. In this respect, it is more advantageous if the gap distance is in a range between 0.5 mm and 0.9 mm. A universal usability of the cutting device is given when the gap distance is about 0.7 mm. This value is subject to tolerances, the tolerances are relatively uncritical. It is of particular advantage if the cutting edge is provided with a toothing. The distance between the tooth ridges lies in the order of magnitude of the material thickness of the coverings to be cut, ie between 1 mm and 5 mm. Preferably, however, the distance of the tooth ridge is greater than 2mm. The teeth have tooth ridges, which are parallel to the axis of rotation of the
Schneidmessers erstrecken, also senkrecht zur Flächennormalen der Breitseitenflächen verlaufen. Die Zahnfirste erstrecken sich vorzugsweise über die gesamte Materialstärke des Schneidmessers und bilden somit eine stumpfe Schneidkante. Die Zahnfirste können aber auch so geschliffen sein, dass sie schräg mit abwechselnder Schrägenrichtung verlaufen, so dass sie verstärkt am Rand des Schnittstreifens in die Oberfläche des Werkstücks eintreten. Beim Schnitt graben sich diese Zähne in die Oberfläche des zu schneidenden Werkstücks ein, um den Materialstreifen aus der Werkstückplatte herauszudrücken. Dabei ist es von Bedeutung, wenn sich das Werkstück auf beiden Tragholmen abstützt. Wenn mit der Schneidevorrichtung dünne Materialplatten geschnitten werden sollen ist es von Vorteil, wenn die Schneidkante reduzierte Horizontalkräfte in die Materialplatte überträgt. Um derartige Horizontalkräfte, die, sofern sich das Werkstück an einem Anschlag abstützt, zu einem wellenförmigen Verwerfen des Werkstücks führen können, werden bevorzugt dadurch eliminiert, dass das Schneidmesser derart am Gestell schwenkbar gelagert ist, dass die Zähne im Wesentlichen in einer Richtung quer zur Tragebene der Tragholme in den Eintauchschlitz eintauchen. Hierzu ist bevorzugt eine Steuerung des Schneidmes- sers vorgesehen, die bewirkt, dass sich die Schwenkachse des Schneidmessers im Zuge des Schnitz in Horizontalrichtung verlagert. Bevorzugt durchgreift dabei ein ortsfest den Tragholm zugeordneter Steuerstift einen entlang einer Spiralkurve verlaufenden Bogenschlitz im Schneidmesser. In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Schlitzwände des Ein- tauchschlitzes von einer Stirnfläche einer Leiste ausgebildet sind, wobei jeweils eine Leiste an einer Profilrippe eines Tragholms befestigt ist. Es ist ferner vorgesehen, dass die Breitseiten der Klinge und/ oder die Leisten mit einer Antihaft- beschichtung versehen sind. Insbesondere die Schlitzwände sind mit einer Haftbeschichtung versehen. Bei der Haftbeschichtung kann es sich um eine Si- likonbeschichtung oder um eine PTFE (Teflonbeschichtung) handeln. Die Be- schichtung kann als Lack aufgetragen werden. Es handelt sich um eine Be- schichtung, wie sie grundsätzlich beispielsweise von Backformen vorbekannt ist. Mit einer derart ausgebildeten Vorrichtung lassen sich auch klebstoffbeschichtete Fliesen schneiden. Zufolge der Antihaftbeschichtung der Klinge und der Leisten ist dort ein Anhaften des Klebstoffs vermindert. Auch die Verzahnung des Schneidmessers kann mit einer Antihaftbeschichtung versehen sein. Insbesondere bei sehr schmalen Schlitzweiten wird eine ungewollte Verklebung zwischen Schlitzwand und Schneidmesserbreitseite bzw. Schneidmesserverzahnung verhindert. Die Vorrichtung ist auch zum Zerteilen von Schieferplat- ten geeignet. Extending cutting blade, ie perpendicular to the surface normal of the broad side surfaces. The tooth ridges preferably extend over the entire material thickness of the cutting blade and thus form a blunt cutting edge. The tooth ridges can also be ground so that they run obliquely with alternating oblique direction, so that they enter reinforced at the edge of the cutting strip in the surface of the workpiece. When cut, these teeth dig into the surface of the workpiece to be cut to push the strip of material out of the workpiece plate. It is important if the workpiece is supported on both supporting beams. If thin material plates are to be cut with the cutting device, it is advantageous if the cutting edge transmits reduced horizontal forces into the material plate. To such horizontal forces, which, if the workpiece is supported on a stop, to a wave-shaped warping of the workpiece are preferably eliminated in that the cutting blade is pivotally mounted on the frame so that the teeth are immersed in a substantially transverse direction to the support plane of the support bars in the immersion slot. For this purpose, a control of the cutting knife is preferably provided, which causes the pivot axis of the cutting blade moves in the course of the carving in the horizontal direction. In this case, a control pin assigned in a stationary manner to the carrier beam preferably engages through an arc slot running along a spiral curve in the cutting blade. In a preferred embodiment of the invention it is provided that the slot walls of the immersion slot are formed by an end face of a strip, wherein in each case a strip is attached to a profile rib of a supporting beam. It is further provided that the broad sides of the blade and / or the strips are provided with a non-stick coating. In particular, the slot walls are provided with an adhesive coating. The adhesive coating may be a silicone coating or a PTFE (Teflon coating). The coating can be applied as a varnish. It is a coating, as it is in principle already known, for example, from baking pans. With a device designed in this way, adhesive-coated tiles can also be cut. Due to the non-stick coating of the blade and the strips, adhesion of the adhesive is reduced there. The toothing of the cutting blade may be provided with a non-stick coating. In particular, with very narrow slot widths unwanted bonding between the slot wall and Schneidmesserbreitseite or cutting blade teeth is prevented. The device is also suitable for cutting slate plates.

The disclosure of DE 10 2009 003 490 A1 is therefore fully incorporated in this application.
Die Zeichnungen zeigen ein Gestell 1, welches zwei Füße 3 besitzt, die jeweils am Ende zweier parallel zueinander verlaufenden Tragholme 2 angeordnet sind und die Tragholme 2 auf Abstand zueinander halten. Der Abstand der beiden Tragholme 2 definiert einen Eintauchschlitz 6. The drawings show a frame 1, which has two feet 3, which are respectively arranged at the end of two mutually parallel support beams 2 and hold the support beams 2 at a distance from each other. The distance between the two supporting beams 2 defines a submerged slot 6.
An einem Ende der beiden Tragholme 2 ist um eine Anlenkstelle 15 ein At one end of the two support beams 2 is a pivot point 15 a
Schneidmesser 10, welches aus einer Stahlklinge besteht, schwenkbar angelenkt. Das Schneidmesser 10 besitzt eine auf einem Bogen verlaufende Schneidkante 12, die mit einer Vielzahl von Zähnen 13 versehen ist. Die Zähne 13 besitzen Zahnfirste, die parallel zur Flächennormalen der Breitseitenflächen 11 des Schneidmessers 10 verlaufen und sich über die gesamte Materialstärke des Schneidmessers 10 erstrecken. Cutting knife 10, which consists of a steel blade, pivotally articulated. The cutting blade 10 has an arcuate cutting edge 12 provided with a plurality of teeth 13. The teeth 13 have Zahnfirste, parallel to the surface normal of the broad side surfaces 11 of Blade 10 extend and extend over the entire thickness of the cutting blade 10.
Die Materialstärke des Schneidmessers 10 ist größer als der halbe Abstand zwischen den beiden Schlitzwänden 4, die die Breite des Eintauchschlitzes 6 defi- nieren. Beim Ausführungsbeispiel werden die Schlitzwände 4 von Leisten 5 ausgebildet, die auf schwalbenschwanzförmig profilierten Profilrippen 7 der aus Aluminium bestehenden Tragholme 2 aufgesteckt sind. The material thickness of the cutting blade 10 is greater than half the distance between the two slot walls 4, which define the width of the immersion slot 6. In the embodiment, the slot walls 4 are formed by strips 5, which are plugged onto dovetail-shaped profiled ribs 7 of the existing aluminum supporting beams 2.
Die Figur 3 zeigt, dass die Leisten 5 Kanten 4' ausbilden. Es handelt sich dabei um Tragholmkanten 4', an denen sich das zu schneidende Werkstück 9 abstüt- zen kann. Aus der Figur 3 ist ferner zu erkennen, dass jede der beiden Breitseiten 11 des in den Eintauchschlitz 6 eingetauchten Schneidmessers 10 einen Spaltabstand zur Tragholmkante 4' besitzt. Da die Schlitzwände 4 parallel zueinander verlaufen, haben die Schlitzwände 4 denselben Spaltabstand zur Breitseite 11 des Schneidmessers 10, den auch die Tragholmkante 4' besitzt. Aus den Zeichnungen ist ferner zu entnehmen, dass auf den Tragholmen 2 ein drehbarer Anschlag 8 angeordnet ist. Dieser Anschlag 8 ist im Wesentlichen eine Justierhilfe. Wegen der Verzahnung der Schneidkante 12, deren Zähne 13 beim Schnitt in das Werkstück 9 eintauchen, wird das Werkstück 9 beim Schnitt kaum über die Tragholme 2 verschoben. Das Gelenk 15 ist so ausgebildet, wie es in der DE 10 2009 043 992 AI beschrieben ist. Dann ist eine Verlagerung des Werkstücks 9 beim Schnitt gänzlich verhindert. Die DE 10 2009 043 992 AI wird deshalb hinsichtlich der Ausgestaltung des Schwenklagers 15 vollinhaltlich mit in diese Anmeldung einbezogen. Die wesentlichen Elemente des Gelenks 15 sind in den Figuren 5 und 6 dargestellt. Die Schwenkachse 17 (um die das Schneidmesser 10 verschwenken kann) ist zwar fest am Schneidmesser 10 befestigt, aber in einem Horizontalschlitz 18 des Tragholms 2 verlagerbar. Ein Steuerzapfen 19, der fest am Gestell 1 bzw. an den Tragholmen 2 befestigt ist, durchgreift einen Bogenschlitz 16 des Schneidmessers 10. Der Bogenschlitz 16 verläuft bezogen auf den die Schwenkachse ausbildenden Zapfen 17 auf einer Spiralkurve. In der in Figur 5 dargestellten Betriebsstellung, in der das Schneid- messer hochgeschwenkt ist, hat der Zapfen 17 den geringsten Abstand zum Steuerzapfen 19. Wird das Schneidmesser 10 geschwenkt, so durchläuft der Steuerzapfen 19 den Bogenschlitz 16, wobei sich der Abstand zwischen FIG. 3 shows that the strips 5 form edges 4 '. These are carrier spar edges 4 ', on which the workpiece 9 to be cut can support. It can also be seen from FIG. 3 that each of the two broad sides 11 of the cutting blade 10 immersed in the immersion slot 6 has a gap distance from the supporting beam edge 4 '. Since the slot walls 4 are parallel to each other, the slot walls 4 have the same gap distance to the broad side 11 of the cutting blade 10, which also has the carrier beam edge 4 '. It can also be seen from the drawings that a rotatable stop 8 is arranged on the supporting bars 2. This stop 8 is essentially an adjustment aid. Because of the toothing of the cutting edge 12, the teeth 13 dive when cutting into the workpiece 9, the workpiece 9 is hardly moved over the support beams 2 during the cut. The joint 15 is formed as described in DE 10 2009 043 992 AI. Then a displacement of the workpiece 9 during the cut is completely prevented. The DE 10 2009 043 992 AI is therefore fully incorporated into this application with regard to the design of the pivot bearing 15. The essential elements of the joint 15 are shown in FIGS. 5 and 6. Although the pivot axis 17 (about which the cutting blade 10 can pivot) is fixedly attached to the cutting blade 10, but displaceable in a horizontal slot 18 of the supporting beam 2. One Control pin 19, which is fixedly mounted on the frame 1 and on the supporting bars 2, passes through an arcuate slot 16 of the cutting blade 10. The curved slot 16 extends relative to the pivot axis forming pin 17 on a spiral curve. In the operating position shown in Figure 5, in which the cutting blade is swung up, the pin 17 has the smallest distance to the control pin 19. If the cutting blade 10 is pivoted, the control pin 19 passes through the curved slot 16, wherein the distance between
Schwenkachse 17 und dem Steuerzapfen 19 vergrößert. Dies hat zur Folge, dass die Schwenkachse 17 während des Schnitts in dem Horizontalschlitz 18, also in Erstreckungsrichtung der Tragholme 2, wandert. Für den Schnitt hat das die Folge, dass der in der Figur 4 mit der Bezugsziffer 13 bezeichnete Zahn sich beim Schnitt im Wesentlichen nur nach unten, also in einer Richtung quer zur Erstreckungsrichtung des Tragholms 2 verlagert. Auf das Werkstück 9 werden somit keine in Horizontalrichtung gerichteten Kräfte ausgeübt. Auch dünn- wandige Werkstücke 9 können so geschnitten werden, ohne dass sie Wellen werfen. Swivel axis 17 and the control pin 19 increases. This has the consequence that the pivot axis 17 during the cut in the horizontal slot 18, ie in the extension direction of the support beams 2, wanders. For the cut, this has the consequence that the tooth denoted by the reference numeral 13 in FIG. 4 is displaced substantially only downwards, ie in a direction transverse to the direction of extension of the carrier spar 2, during the cut. Thus, no forces directed in the horizontal direction are exerted on the workpiece 9. Even thin-walled workpieces 9 can be cut without causing waves.
Unter Verwendung unterschiedlich gestalteter Leisten 5 wurde in Versuchen der optimale Spaltabstand ermittelt. Es wurden dabei Leisten 5 verwendet, die voneinander verschiedene Materialstärken besitzen. Aus der Tabelle 1 ist zu entnehmen, dass sich 5mm starke Vinylbeläge bei Spaltbreiten von 0,45mm, 0,7mm, 0,85mm, 1,1mm und 1,35 mm mit hoher Qualität schneiden lassen. Es treten immer glatte Schnittkanten auf. Allerdings ist bei geringen Spaltbreiten eine sehr hohe Kraft auf den Griff 14 des Schneidmessers 10 aufzuwenden. Spaltbreite Vinyl-Belag Vinyl-Belag Vinyl-Belag PVC-Fliese [mm] 5mm 4mm 2,5mm 1,8mm Using differently shaped strips 5 the optimum gap distance was determined in experiments. There were used strips 5, which have mutually different material thicknesses. From Table 1 it can be seen that 5mm thick vinyl coverings can be cut with high quality at gap widths of 0.45 mm, 0.7 mm, 0.85 mm, 1.1 mm and 1.35 mm. There are always smooth cutting edges. However, with small gap widths, a very high force must be exerted on the handle 14 of the cutting blade 10. Slit width Vinyl flooring Vinyl flooring Vinyl flooring PVC tile [mm] 5mm 4mm 2.5mm 1.8mm

Tabelle 1 Bei Versuchen, die mit 4mm starken Vinylbelägen vorgenommen wurden, zeigte sich, dass es bei großen Spaltbreiten zu leicht ausgefransten Schnittkanten kommt. Dieser Effekt zeigte sich bei Vinylbelägen mit einer Materialstärke von 2,5mm bereits bei Spaltbreiten von 1,1mm. Bei PVC-Fliesen mit einer Materialstärke von 1,8mm führten Spaltbreiten von 0,85mm bereits zu leicht ausgefrans- ten Kanten. Die Ergebnisse mit leicht ausgefransten Kanten waren aber insgesamt verwertbar. Optimale Ergebnisse werden erzielt, wenn die Spaltbreite jeweils zwischen Schneidmesserbreitseite 11 und Tragholmkante 4' bzw. Schlitzwand 4 im Bereich zwischen 0,4 und 0,7mm liegt, beispielsweise 0,5 mm beträgt. Dann ist die Schneidevorrichtung nicht nur geeignet, Vinylbeläge mit ei- ner Materialstärke zwischen 2,5mm und 5mm sauber zu zerteilen. Mit der Vor- richtung können auch PVC-Fliesen mit einer Materialstärke von nur 1,8mm sauber zerteilt werden. Beim Zerteilen von materialstarken Vinylbelägen ist zwar ein etwas höherer Kraftaufwand erforderlich. Dieser ist jedoch wegen des Hebelarms, mit dem der Griff 14 am Schneidmesser 10 befestigt ist, hinnehm- bar. Table 1 Experiments carried out with 4mm thick vinyl flooring showed that with large gap widths slightly frayed cut edges occur. This effect was already evident for vinyl coverings with a material thickness of 2.5 mm at gap widths of 1.1 mm. For PVC tiles with a material thickness of 1.8mm, gap widths of 0.85mm already led to slightly frayed edges. However, the results with slightly frayed edges were overall usable. Optimum results are achieved if the gap width between the cutting blade broad side 11 and the supporting beam edge 4 'or the slot wall 4 is in the range between 0.4 and 0.7 mm, for example 0.5 mm. Then the cutting device is not only suitable for neatly cutting vinyl coverings with a material thickness between 2.5mm and 5mm. With the direction, even PVC tiles with a thickness of only 1.8mm can be cut cleanly. When cutting material-rich vinyl coverings, a slightly higher force is required. However, this is because of the lever arm, with which the handle 14 is fixed to the cutting blade 10, acceptable.
Soll die Schneidevorrichtung lediglich für Vinylbeläge mit einer Materialstärke zwischen 2,5mm und 5mm verwendet werden, so liegt der nutzbare Spaltab- standsbereich zwischen 0,5mm und 1,4mm. If the cutting device is to be used only for vinyl coverings with a material thickness between 2.5mm and 5mm, the usable gap distance range is between 0.5mm and 1.4mm.
Grundsätzlich sind auch geringere Spaltabstände bis hinunter zu 0,2mm mög- lieh. Dann erhöht sich jedoch der Kraftaufwand. In principle, smaller gap distances down to 0.2 mm are possible. But then the effort increases.
Wie aus der Figur 4 hervorgeht, graben sich die Zähne 13 in das Werkstück 9, so dass der aus dem Werkstück 9 herausgedrückte Materialstreifen 9' auf seiner nach oben weisenden Seite eine Kerbung erhält. Diese Kerbung wirkt schnitt- kr af tvermindernd . Die beiden Breitseiten 11 des Schneidmessers 10 sind mit einer Antihaftbe- schichtung versehen. Auch die Schneidkante 12 bzw. die Zähne 13 können mit einer derartigen Antihaftbeschichtung versehen sein. Auch die Leisten 5 sind mit einer Antihaftbeschichtung versehen. Zumindest sind die Schlitzwände 4 bzw. die Leisten im Bereich der oberen Kante 4' mit einer Antihaftbeschichtung versehen. Bei der Antihaftbeschichtung kann es sich um eine Silikonbeschich- tung oder um eine PTFE-Beschichtung handeln. As can be seen from FIG. 4, the teeth 13 dig into the workpiece 9, so that the material strip 9 'pushed out of the workpiece 9 receives a notch on its upwardly pointing side. This notch reduces cut-to-size. The two broad sides 11 of the cutting blade 10 are provided with a non-stick coating. Also, the cutting edge 12 and the teeth 13 may be provided with such a non-stick coating. The strips 5 are provided with a non-stick coating. At least the slot walls 4 and the strips in the region of the upper edge 4 'are provided with a non-stick coating. The non-stick coating may be a silicone coating or a PTFE coating.
