Den Gegenstand, vorliegender Erfindung bildet eine Neuerung an dem durch Patent No. 50356 geschützten Pappenritzmesser, welche darin besteht, dafs statt des keilförmigen Messers ein pflugscharartiger Hobel angebracht wird, bei welchem ebenfalls die eine geradlinige Mittelschneide in zwei schwalbenschwanzförmig gebogene Schneiden ausläuft. Während der Vorgang beim Ausschneiden bezw. Ritzen der Pappe im wesentlichen derselbe bleibt, tritt eine leichtere Abführung des ausgehobenen Spanes ein, welche gleichzeitig eine bessere Beobachtung des Schneidvorganges ermöglicht. Zu diesem Zweck ist das Messer bezw. der Hobel nur einseitig befestigt, indem eine Seite desselben mit einer geraden Verlängerung versehen ist, mit welcher das Messer an einer Führung des Messerbalkens durch Schraubenbolzen befestigt wird.The subject matter of the present invention is an innovation in the patent no. 50356 protected cardboard scoring knife, which consists in the fact that instead of the wedge-shaped knife, a A ploughshare-like plane is attached, which also has a straight central cutting edge ends in two dovetail-shaped curved cutting edges. During the process of cutting or. Scratches the Cardboard remains essentially the same, the excavated chip can be carried away more easily one, which at the same time enables a better observation of the cutting process. To this Purpose is the knife respectively. the plane attached only on one side by adding one side of it is provided with a straight extension with which the knife on a guide of the Knife bar is fastened by screw bolts.

An.dem Messerbalken α ist der Messerhalter b verschiebbar und an ihm das Ritzmesser bezw. der Hobel c mittelst zweier in Ausschnitten des ersteren lagernden Schraubenbolzen d d an der lothrechten Verlängerung c3 befestigt. Die geradlinige Schneide c1 läuft schwalbenschwanzförmig in zwei gebogene und schräg gegen einander stehende Schneiden c2 c2 aus. Die auf dem Tisch t ruhende Pappe ρ wird dem Messer entgegengeführt.The knife holder b is displaceable on the knife bar α and the scoring knife and / or on it. the planing c by means of two cut-outs in the former overlying bolt dd attached to the extension lothrechten c. 3 The straight cutting edge c 1 runs out in the shape of a dovetail into two curved cutting edges c 2 c 2 which are at an angle to one another. The cardboard ρ resting on the table t is guided towards the knife.
