Description

Kreismesser mit unterbrochener Schneide, dessen Schneidendurchmesser durch gegenseitiges Verdrehen zweier Körper verändert werden kann. Kreismesser mit unterbrochener Schneide, deren Messer aus einzelnen im Kreise angeordneten Lamellen bestehen, welche durch Verstellen von Ringen o. dgl. so nach außen oder innen verstellt werden, daß die Schneide einen größeren oder kleineren Durchmesser erhält, sind bereits bekannt.Circular knife with interrupted cutting edge, its cutting edge diameter can be changed by mutually twisting two bodies. Circular knife with interrupted cutting edge, the knives of which are made up of individual lamellae arranged in a circle exist, which by adjusting rings o. The like. So adjusted outwards or inwards that the cutting edge is given a larger or smaller diameter already known.

Die Erfindung bezieht sich auf ein derartiges Kreismesser und besteht in der Kombination der Ausführung des Kreismessers dahirgeliend, daß die verstellbaren Messer einersrits in einem verdrehbaren Körper, über dessen Umfang sie nur so weit als erforderlich hinausragen, gehalten sind, während sie sich anderseits gegen einen Anschlag anlegen, mit der Ausführung der einzelnen Messer, dergestalt, daß dieselben aus dünnem Bandstahl Ziergestellt sind.The invention relates to and consists of such a circular knife in the combination of the execution of the circular knife dahirgeliend that the adjustable Knife in a twistable body, over the circumference of which it is only so far stick out as necessary, while on the other hand they stand against one Create stop, with the execution of the individual knives, in such a way that the same are made of thin strip steel.

Bei den bekannten, einleitend beschriebenen Kreismessern mit unterbrochener Schneide haben die Messer eine mehr oder weniger große Dicke, von welcher die Schneiden von beiden Seiten lier herausgearbeitet werden müssen, wobei die Schneiden bei den einzelnen Messern niemals oder nur unter Benutzung besonderer und teurer Arbeitsvorrichtungen genau an ein und dieselbe Stelle kommen. Weichen aber die Schneiden der einzelnen Messer, was schon frei deren Verstellung zwecks Veränderung des Schneidendurchmessers eintreten kann, nur ein klein wenig in ihrer Stellung zueinander voneinander ah, so wird selbstverständlich der Schnitt des Kreismessers ein .breiterer, was für viele Zwecke unstatthaft i"st.In the known, initially described circular knives with interrupted Cutting edge, the knives have a more or less large thickness, from which the cutting edges must be worked out from both sides, with the cutting edges on the individual knives never or only with the use of special and expensive work equipment come to exactly the same place. But give way to the cutting edge of the individual Knife, what is already free their adjustment for the purpose of changing the cutting diameter can occur only a little bit in relation to each other Ah, so of course the cut of the circular knife becomes a wider, what for many purposes are inadmissible.

Beim Erfuidungsgegenstand; stimmen die einzelnen Messerschneiden stets in ihrer Stellung zueinander überein deshalb, weil sie aus dünnem Bandstahl bestehen, welcher selbst unmittelbar als Schneide bzw. Messer benutzt oder an welchem die Schneide angeschliffen wird, was mit Leichtigkeit innerhalb ganz geringer Fehlergrenzen geschehen kann, welche praktisch unerheblich sind. Diese übereinstimmung aller Schneiden der einzelnen verstellbaren Messer wird noch dadurch gewährleistet, daß sie nur so weit, als für die Schneidarbeit erforderlich ist, aus ihrem verdrehbaren Haltekörper herausragen, wodurch zugleich ihre Standhaftigkeit erhöht wird.With the subject matter of the invention; the individual knife edges are always correct coincide in their position to one another because they are made of thin strip steel, which itself is used directly as a cutting edge or knife or on which the Edge is sharpened, which can be done with ease within a very small margin of error can happen, which are practically irrelevant. This coincidence of all cutting edges the individual adjustable knife is still guaranteed by the fact that they only as far as is necessary for the cutting work from its rotatable holding body stand out, which at the same time increases their steadfastness.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Abb. i im Aufriß und in Abb.2 im Durchschnitt veranschaulicht. Auf der Welle i sitzt der Spannkörper 2 fest und auf dessen Nabe 2, der Körper 3 drehbar. In ringförmig angeordneten Löchern 3a des letzteren sind mittels Zapfen 4a die einzelnen Messer 4. aus dünnem Bandstahl drehbar, welcher entweder selbst unmittelbar als Schneide dient oder an welchem oben die Schneide angeschliffen wird. Die Messer 4 legen sich gegen das äußere Ende hin gegen im Spannkörper 2 befestigte Stifte 2b. Wenn der Körper 3 mittels seines Griffzapfens 3b im Bogenschlitz 2d des Spannkörpers 2 in Abb. i nach rechts hin verdreht wird, so bewegen sich die Messer 4 nach außen, bis sie aus den verschiedenen Tangentialstellungen in die Radialstellung als dem größten einzustellenden Schneidendurchmesser gelangen, so daß also jeder beliebige Schneidendurchmesser einstellbar ist. Durch den von der Wellenmutter 6 (Abb. 2) angezogenen Cespannkörper 5 werden die Messer auf dem Rand 2r des Spannkörpers 2 festgehalten, wobei für die Stifte 2b in ihm Ausnehmungen 5- vorgesehen sind.In the drawing, an embodiment of the subject matter of the invention is illustrated in Fig. 1 in elevation and in Fig. 2 in section. The clamping body 2 is firmly seated on the shaft i and the body 3 is rotatable on its hub 2. In ring-shaped holes 3a of the latter, the individual knives 4. made of thin strip steel can be rotated by means of pins 4a, which either directly serves as a cutting edge or on which the cutting edge is ground at the top. The knives 4 lie against the outer end against pins 2b fastened in the clamping body 2. If the body 3 is rotated to the right by means of its grip pin 3b in the arc slot 2d of the clamping body 2 in Fig that any cutting diameter is adjustable. By means of the clamping body 5 tightened by the shaft nut 6 (Fig. 2), the knives are held on the edge 2r of the clamping body 2, with recesses 5 being provided in it for the pins 2b.

In Abb. i ist das Aufreißen einer Ausschußzigarette y und in Abb. 2 das Aufschneiden einer Kartonschachtel 8 gezeigt, wobei das Überzugspapier 81, welches das Bodenstück 81, und Hals 8c mit dem Deckel 8d verbindet, längs der Fuge zwischen Bodenstürk 8b und Deckel öd zertrennt wird.- In beiden Fällen ragen die Messer 4 nur so weit über dem Umfang der Spannkörper 2 und 5 hinaus, als erforderlich isst.In Fig. I the tearing open of a rejected cigarette y and in Fig. 2 the cutting open of a cardboard box 8 is shown, with the covering paper 81, which connects the base piece 81 and neck 8c to the lid 8d, along the joint between the base door 8b and the lid öd is severed.- In both cases, the knives 4 protrude only as far beyond the circumference of the clamping body 2 and 5, as is necessary to eat.
