Description
Die Erfindung bezieht sich auf eine Schneidleiste für Papierschneidemaschinen zum Einspannen in einem rinnenförmigen, im Schneidtisch angeordneten Tragkörper. Die gebräuchlichen Schneidleisten für -Papierschneidemaschinen bestehen vorwiegend aus Holzoder Kunststoff. Bei jedem Schnitt dringt das Messer etwas in die Schneidleiste ein, deren Härte so bemessen ist, daß die Leiste einerseits dem Schneidgut einen ausreichend großen Auflagewiderstand bietet und andererseits eine möglichst kleine Abnutzung des Messers ergibt. Die Schneidleisten müssen daher oft erneuert werden.The invention relates to a cutting bar for paper cutting machines for clamping in a channel-shaped support body arranged in the cutting table. The most common cutting sticks for paper cutting machines exist made of wood or plastic. With every cut the knife penetrates the cutting stick a little one, the hardness of which is such that the bar on the one hand the material to be cut one offers sufficiently large contact resistance and, on the other hand, as small as possible Wear of the knife results. The cutting sticks therefore often have to be renewed.
Aufgabe der Erfindung ist die Schaffung einer Schneidleiste für Papierschneidemaschinen, die nicht nur die Vorteile der bekannten Schneidleisten hat, sondern auch praktisch keiner Abnutzung unterliegt, so daß sie als Dauerschneidleiste bezeichnet werden kann.The object of the invention is to create a cutting stick for paper cutting machines, which not only has the advantages of the well-known cutting sticks, but also practical not subject to wear and tear, so that they are referred to as permanent cutting strips can.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schneidleiste von einem Paket aus einer Vielzahl von elastischen Elementen in Form von Stäben, Streifen oder Fäden gebildet ist, die in Schneidrichtüng angeordnet sind, so daß das in dem Tragkörper eingespannte Paket dieser Elemente dem auf ihm liegenden Schneidgut den nötigen Auflagewiderstand bietet, während die beim Schneidvorgang an ihrer Spitze von der Messerschneide getroffenen Elemente seitlich ausweichen und die Messerschneide an sich vorbeigleiten lassen.According to the invention, this object is achieved in that the cutting bar from a package of a large number of elastic elements in the form of rods, Strips or threads are formed which are arranged in the cutting direction so that the package of these elements clamped in the support body to the material to be cut lying on it provides the necessary contact resistance while the cutting process is at its tip Elements hit by the knife edge evade sideways and the knife edge let it slide past you.
Die Elemente bestehen z. B. aus Kunststoffborsten. Diese haben in ihrer Längsrichtung eine große Steifigkeit; sie weichen aber zur Seite schon bei der Einwirkung nur kleiner Kräfte aus.The elements consist e.g. B. made of plastic bristles. These have in great rigidity in their longitudinal direction; but they give way to the side the action of only small forces.
Dieses ist auch der Fall, wenn die Kunststoffborsten sehr eng aneinanderstehen bzw. zu einem Paket zusammengefaßt sind; beim Zusammendrücken benachbarter Kunststoffborsten geht ihr kreisförmiger Querschnitt - etwa in einen solchen mit Sechseckform über.This is also the case when the plastic bristles are very close to one another or are combined into a package; when pressing adjacent plastic bristles together its circular cross-section merges into one with a hexagonal shape, for example.
Wenn das Schneidmesser .nach dem Schnitt in die Ruhestellung zurückgeht, nehmen die Kunststoffborsten infolge ihrer Elastizität wieder die alte Lage ein, so daß der durch den Messereintritt gebildete Schlitz in der Schneidleiste sich wieder schließt.When the cutting knife returns to the rest position after the cut, the plastic bristles take up their old position again due to their elasticity, so that the slot formed by the knife entry in the cutter bar is closes again.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt. Das Schneidgut i liegt auf der Schneidleiste, die in einem rinnenförmigen, im Schneidtisch angeordneten Tragkörper eingesetzt und im wesentlichen durch das Paket z aus Kunststoffborsten gebildet ist. Die Kunststoffforsten -stehen aufrecht, so daß die Schneidrichtung des Messers parallel zu ihrer Längsrichtung ist. Als rinnenförmiger Tragkörper zur Aufnahme des Paketes aus Kunststoffborsten ist in dem Schneidtisch .4 der Maschine ein Winkeleisen 5 eingelassen, dem zum Festspannen der erfindungsgemäß ausgebildeten Schneidleiste Preß-und Zustellkeile 6 und 7 zugeordnet sind.The drawing shows an embodiment of the subject matter of the invention shown schematically. The item to be cut i lies on the cutting bar, which is in one Channel-shaped, arranged in the cutting table support body used and essentially is formed by the package z from plastic bristles. The plastic forests stand upright so that the cutting direction of the knife is parallel to its longitudinal direction is. As a channel-shaped support body for receiving the package made of plastic bristles an angle iron 5 is embedded in the cutting table .4 of the machine for clamping the cutting bar designed according to the invention is assigned pressing and infeed wedges 6 and 7 are.
