Abstract

The knife blade (7) is for a conical knife. At least one surface of the blade has a recess (6) in the material. This recess is at least 0.05 mm deep and extends over at least 30% of the surface. The recess in the material may be in the form of at least one groove running along the cutting edge and at least 1 mm away from it. The cutting edge may be recessed in small cutouts. The recess may be forged into the blade blank or may be ground or otherwise machined into the finished blade.

Description

Die Erfindung betrifft eine Messerklinge zum Schneiden von schwierigem Schnittgut.The invention relates to a knife blade for cutting difficult clippings.

Bekannt sind Messerklingen, bei denen eine oder zwei Schneiden durch ein Paar oder zwei Paare konischer Seitenflächen gebildet werden. Die die Schneide bildenden Seitenflächen können flachkonisch, ballig oder hohl ausgebildet sein.Knife blades are known in which one or two cutting edges are provided by a pair or two pairs of conical side surfaces are formed. The cutting edge Side surfaces can be flat-conical, spherical or hollow.

Beim Schneiden von tiefen Schnitten befinden sich die die Schneide bildenden Flächen über der gesamten Höhe in Kontakt mit dem Schnittgut. Dies führt dazu, daß das Schnittgut eine Quetschung über der Eingriffsfläche erfährt, insbesonder bei schwierigem Schnittgut, wie Fleisch, Innereien, Wurst, Hartkäse, Brot aber auch Holz und Kunststoffe.When cutting deep cuts, the surfaces forming the cutting edge are located in contact with the clippings over the entire height. This leads to the fact that Cuttings experience a bruise over the engagement surface, especially at difficult cuttings, such as meat, offal, sausage, hard cheese, bread, but also Wood and plastics.

Bei Käsemessern wird diese Quetschung dadurch vermindert, daß Teile aus der Messerklinge herausgestanzt werden. Neben optischen Mängeln führt dies zu einer erheblichen Instabilität der Messerklinge, so daß sie für andere Schneidzwecke kaum eingesetzt werden kann.In cheese knives, this crushing is reduced by the fact that parts from the Knife blade are punched out. In addition to visual defects, this leads to a considerable instability of the knife blade, so that it is hardly used for other cutting purposes can be used.

Der in Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, die Reibung zwischen Schnittgut und Messer und damit die Quetschung des Schnittgutes zu verringern, ohne die Messerklinge merkbar zu schwächen oder deren Optik wesentlich zu verändern. Dies wird dadurch erreicht, daß eine Materialrücknahme auf den Seitenflächen der Messerklinge vorgesehen ist, die eine Tiefe von mindestens 0.05 mm aufweist, mindestens 30% der Oberfläche umfaßt und mindestens 1 mm von der Schneide entfernt beginnt, wobei die Schneide selbst in kleinen Ausschnitten zurückgenommen sein und somit eine Art Säge bilden kann.The invention specified in claim 1 is based on the object Friction between the clippings and the knife and thus the crushing of the clippings to reduce without noticeably weakening the knife blade or its appearance to change significantly. This is achieved by taking back materials is provided on the side surfaces of the knife blade, which has a depth of at least 0.05 mm, covers at least 30% of the surface and at least 1 mm starts from the cutting edge, the cutting edge even in small sections can be withdrawn and thus form a kind of saw.

Versuche haben gezeigt, daß eine solche Materialrücknahme auf der Oberfläche der die Schneiden bildenden Flächen den gewünschten Effekt erzielt.Experiments have shown that such material withdrawal on the surface of the Cut forming surfaces achieved the desired effect.

Eine vorteilhafte Ausbildung der Erfindung ist in Anspruch 2 angegeben. Die Materialrücknahme erstreckt sich in einer oder mehreren Bahnen in etwa parallel zur Schneide.An advantageous embodiment of the invention is specified in claim 2. The Material take-back extends approximately parallel to one or more lanes Cutting edge.

Eine weitere vorteilhafte Ausführung der Erfindung ist in Anspruch 3 angegeben. Die Materialrücknahme befindet sich zusätzlich in unterbrochenen Abschnitten an der Schneide.A further advantageous embodiment of the invention is specified in claim 3. The Material return is also in interrupted sections on the Cutting edge.

Die Materialrücknahmen können am Rohmesser bereits vorgesehen sein oder am fertigen Messer durch Schleifen, Ätzen oder ähnlichen Vorgängen erzeugt werden.The material returns can already be provided on the raw knife or on the finished one Knives are produced by grinding, etching or similar processes.
