KLASSE SS: Papierfabrikation.CLASS SS: Paper manufacture.
Patentirt im Deutschen Reiche vom 17. April 1889 ab.Patented in the German Empire on April 17, 1889.
Behufs Herstellung von Zellstoff wird in der Regel das geschälte Holz durch Sägen in Scheiben von etwa 30 bis 60 mm Dicke geschnitten. Diese Vorbereitung des Holzes erfordert aber viel Kraft und Arbeitslohn und ergiebt aufser dem bedeutenden Verschleifs an Sägen u. s. w. eine Menge von Sägespänen, die die Herstellung guten und reinen Zellstoffes beeinträchtigen.For the production of pulp, the peeled wood is usually cut into Cut slices about 30 to 60 mm thick. This requires preparing the wood but a lot of strength and wages and besides the considerable wear and tear it shows Sawing, etc. a lot of sawdust, which makes the production of good and pure pulp affect.
Die bis heute im Gebrauch befindlichen drehbaren Holzschneide- oder Hackmaschinen sind für das Schneiden von solchen dicken Holzscheiben nicht zu gebrauchen und ist deshalb die auf beiliegender Zeichnung ersichtliche Schneidvorrichtung hergestellt worden, die es ermöglicht, auch vermittelst der drehbaren Messerscheibe Holzscheiben von 30 mm und mehr Dicke zu schneiden.The rotatable wood cutting or chopping machines that are still in use today are not to be used for cutting such thick wooden slices and is therefore the cutting device shown in the accompanying drawing has been made which it allows, also by means of the rotating knife disc, wooden discs of 30 mm and to cut more thickness.
Die Vorrichtung besteht aus dem Messer Ax dem Spannbügelrahmen B und der für diese Theile erforderlichen Messerscheibe. Das Messer A wird in dem Spannbügelrahmen B festgeschraubt. Der Rahmen umschliest mit dem einen Ende die Befestigungsmutter C der Messerscheibenwelle D und wird auf die Messerscheibe geschraubt. Um dem Messer eine vollkommene Steifigkeit zu geben, sind die Schrauben S1, S2 und S3 an dem anderen Ende des Spannbügelrahmens so beschaffen, dafs man diesen und somit auch das Messer in der Pfeilrichtung Fig. 1 anspannen kann.The device consists of the knife A x the clamp frame B and the knife disc required for these parts. The knife A is screwed into the clamp frame B. One end of the frame encloses the fastening nut C of the cutter disc shaft D and is screwed onto the cutter disc. In order to give the knife complete rigidity, the screws S 1 , S 2 and S 3 at the other end of the clamp frame are designed in such a way that this and thus also the knife can be tightened in the direction of the arrow in FIG.
Ein Nachstellen des Messers ist nicht erforderlich. Statt dessen wird der Schneideschlitz m η geregelt einerseits durch Nachstellen des Gabelstückes E und andererseits durch Drehen des Spannbügelrahmens B um die Achse der Messerscheibe in der Richtung der in Fig. 3 angedeuteten Pfeile. Für die Befestigungsschrauben befinden sich deshalb in der Messerscheibe in den Pfeilrichtungen Schlitzlöcher. It is not necessary to readjust the knife. Instead, the cutting slot m η is regulated on the one hand by readjusting the fork piece E and on the other hand by rotating the clamp frame B about the axis of the knife disk in the direction of the arrows indicated in FIG. There are therefore slotted holes in the knife disc in the directions of the arrows for the fastening screws.
