Abstract
Description
Die Erfindung betrifft ein Abreißmesser eines Klebefilmabrollers, Bandspenders oder dergleichen mit mehreren Zähnen.The The invention relates to a tear-off knife a Klebefilmabrollers, tape dispenser or the like with several Teeth.
Beispielsweise für Klebefilmabroller sind Abreißmesser bekannt, die mehrere Zähne aufweisen, wobei die Zähne in der Regel gleichartig ausgebildet sind. Insbesondere weisen die Zähne in der Regel eine dreieckige Form auf. Beim Verwenden derartiger Abreißmesser kommt es häufig nicht zu einem einwandfreien Abtrennen des Klebefilms. Häufig wird der Klebefilm über eine gewisse Distanz über das Abreißmesser gezogen, ehe der Klebefilm abreißt. Außerdem ist es häufig nicht möglich, eine gerade Schnittkante zu erzeugen.For example for adhesive film dispensers are tearing knives known to have multiple teeth show, with the teeth are usually formed similar. In particular, the Teeth in usually a triangular shape. When using such Abreißmesser it happens often not to a perfect separation of the adhesive film. Often the Adhesive film over a certain distance over the tear-off knife pulled before the adhesive film breaks off. Besides, it is often not possible, to create a straight cutting edge.
Aufgabe der vorliegenden Erfindung ist es, die oben beschriebenen Nachteile zu vermeiden.task It is the object of the present invention to overcome the disadvantages described above to avoid.
Gelöst wird diese Aufgabe erfindungsgemäß durch ein Abreißmesser der eingangs genannten Art, bei dem zumindest einige Zähne an ihrem freien Ende eine Ausnehmung aufweisen. Die Ausnehmung der Zähne weist dabei vorzugsweise eine geringere Tiefe auf als die Zwischenräume zwischen den Zähnen. Ein derart gestaltetes Abreißmesser weist bessere Schneideigenschaften auf. Die oben genannten Nachteile können dadurch vermieden werden.Is solved this task according to the invention by a tear-off knife of the type mentioned, in which at least some teeth on her have a recess at the free end. The recess of the teeth points preferably a smaller depth than the spaces between the Teeth. Such a designed tear-off knife has better cutting properties. The above-mentioned disadvantages can thereby be avoided.
Bei einer besonders bevorzugten Ausführungsform kann vorgesehen sein, dass die Ausnehmung in etwa U-förmig ausgebildet ist. Durch diese Maßnahme lassen sich besondere gute Abtrennergebnisse erzeugen.at a particularly preferred embodiment can be provided that the recess formed in approximately U-shaped is. By this measure can produce special good separation results.
Besondere Vorteile ergeben sich, wenn der Ausnehmungsgrund, d. h. die Begrenzungsfläche der Ausnehmung, gegenüber einer Zahnebene geneigt ist. Durch diese Maßnahme kann eine sehr scharfe Schneidkante erzeugt werden. Besonders bevorzugt ist es, wenn die Begrenzungsflächen der Zahnzwischenräume gegenüber einer Zahnebene geneigt sind. Vorzugsweise sind die Begrenzungsflächen der Zahnzwischenräume genauso geneigt wie der Ausnehmungsgrund der Zähne. Die Neigungen bzw. Anschrägungen können dadurch im selben Herstellungsschritt der Abreißmesser ausgebildet werden. In diesem Zusammenhang ist es besonders vorteilhaft, wenn der geneigte Ausnehmungsgrund und/oder die geneigten Begrenzungsflächen der Zahnzwischenräume durch schräges Verstanzen mit einem Formstempel hergestellt sind. Durch schräges Stanzen lassen sich die schrägen Begrenzungsflächen der Zahnzwischenräume und die schrägen Flächen eines Ausnehmungsgrunds besonders einfach herstellen. Besonders gute Schneid- und Abtrennergebnisse ergeben sich, wenn der Ausnehmungsgrund und/oder die Begrenzungsflächen der Zahnzwischenräume einen spitzen Winkel, insbesondere etwa 45°, zur Zahnebene aufweisen.Special Benefits arise when the recessing reason, d. H. the boundary surface of the Recess, opposite a tooth plane is inclined. By this measure can be a very sharp Cutting edge are generated. It is particularly preferred if the boundary surfaces the interdental spaces across from a tooth plane are inclined. Preferably, the boundary surfaces of the Interdental spaces as inclined as the recess base of the teeth. The inclinations or bevels can thereby be formed in the same manufacturing step, the tear-off. In this context, it is particularly advantageous if the inclined Ausnehmungsgrund and / or the inclined boundary surfaces of the interdental spaces sloping Breaks are made with a forming punch. By oblique punching let the beveled boundary surfaces the interdental spaces and the weird ones surfaces make a recess reason particularly easy. Especially Good cutting and separation results arise when the recess and / or the boundary surfaces the interdental spaces have an acute angle, in particular about 45 °, to the tooth plane.
Ein besonders zuverlässiges Abreißen des Randes von Klebefilmen oder Bändern kann sichergestellt werden, wenn die äußeren, insbesondere äußersten Zähne des Abreißmessers ohne Ausnehmungen ausgebildet sind. In diesem Zusammenhang ist es besonders vorteilhaft, wenn die äußeren, insbesondere äußersten Zähne höher sind als zumindest einige der dazwischen liegenden Zähne. Sowohl der Abreißbeginn als auch das Abreißende können dadurch positiv beeinflusst werden.One particularly reliable Tear off the edge of adhesive films or tapes can be ensured when the outer, especially the outermost Teeth of the Abreißmessers are formed without recesses. In this context it is particularly advantageous if the outer, in particular the outermost Teeth are higher as at least some of the intervening teeth. Both the beginning of the tear as well as the tearing off can be positively influenced.
Wenn das Abreißmesser aus einem vernickelten Material ist, insbesondere aus einem vernickelten Kaltband als Trägermaterial hergestellt ist, ist es besonders korrosionsbeständig. Die Dicke der Nickelschicht beträgt vorzugsweise etwa 0,5 bis 1,5 μm.If the tear-off knife is made of a nickel-plated material, in particular of a nickel-plated Cold strip as carrier material made, it is particularly resistant to corrosion. The thickness of the nickel layer is preferably about 0.5 to 1.5 microns.
