Fig. ι stellt die Seitenansicht und Fig. 2 den Grundrifs einer Abrichtmaschine dar. α ist der Arbeitstisch mit der Messerwelle b und dem Anschlag c. Auf dem Tisch liegt ein um den Punkt d drehbarer Schieber e, dessen eine Seite dergestalt gekrümmt ist, dafs das Holz, gleichviel von welcher Breite, stets diese Curve tangirt.Fig. 1 shows the side view and Fig. 2 shows the basic outline of a dressing machine. Α is the work table with the knife shaft b and the stop c. On the table lies a slide e which can be rotated about point d , one side of which is curved in such a way that the wood, regardless of its width, always touches this curve.
Eine Spiralfeder sucht den Schieber fortwährend in seine Ruhelage zurückzudrücken. Hierdurch wird das Holz erstens fest gegen den Anschlag gedrückt, so dafs der Arbeiter nicht mehr nöthig hat, das Holz so tief zu fassen, und dann" wird das Holz· überhaupt festgehalten, wenn es etwa über der Messerwelle entzwei reifsen sollte. Aus dem Gesagten geht hervor, dafs die Messerspalte stets durch den Schieber geschlossen ist. Bei gröfseren Maschinen, wo ein Schieber zu viel Raum einnehmen würde, legt man mehrere über einander, welche nach einander in Wirksamkeit treten, wie in Fig. 3 dargestellt.A spiral spring is constantly trying to push the slide back into its rest position. This firstly presses the wood firmly against the stop, so that the worker no longer has to grasp the wood so deeply, and then "the wood becomes" at all recorded when it should rip in two over the cutter shaft. From what has been said it can be seen that the knife gap is always closed by the slide. With larger ones Machines, where a slide would take up too much space, you put several on top of each other, which come into effect one after the other, as shown in FIG.
