Description

Gegenstand der Erfindung ist ein Fräser zum Weißschälen von Rundhölzern für die Papier- und Zellstoffgewinnung.The invention relates to a milling cutter for whitening round timber for paper and pulp production.

Es gibt schon vielerlei Systeme zum Rinden-und Bastentfernen an Rundhölzern für die Zellstoffindustrie. Aber in allen Fällen ist entweder der Holzverbrauch zu groß oder die Rundhölzer werden nicht ganz von Bast frei, so daß ein teures Nachschälen unbedingt erforderlich ist.There are already many systems for removing bark and bast from round wood for the pulp industry. But in all cases it is either wood consumption too big or the round timbers are not completely free of bast, so expensive re-peeling is absolutely necessary.

Um diesen Umstand zu beseitigen, ist ein Fräser konstruiert, bei dem die Messer sägenartig geformt und beweglich angeordnet sind. Die Messer werden durch Federdruck oder Fliehkraft nach der Außenseite gedrückt und können beim Vorbeistreichen an dem rotierenden Rundholz nach der Fräsermitte nachgeben. Dadurch wird.erreicht, daßdieschmalen sägeblattartigen Fräser sich an jede Unebenheit und Krümmung anpassen und trotzdem aber nicht tief in das Holz einschneiden, sondern nur den Bast an der Außenseite des Holzes abstreifen.In order to eliminate this circumstance, a milling cutter is designed in which the knives are shaped like a saw and are movably arranged. The knives are through Spring pressure or centrifugal force pushed to the outside and can pass by give way on the rotating log towards the center of the cutter. This achieves. that this narrow saw blade-like cutter adapt to any unevenness and curvature and yet do not cut deep into the wood, only the bast on the Strip the outside of the wood.

Der Fräser ist so konstruiert, daß bei etwaigem Stumpfwerden der Fräser dieselben mit ein paar Handgriffen satzweise ausgewechselt werden können.The cutter is designed in such a way that if the cutter becomes blunt the same can be exchanged in sets in a few simple steps.

Abb. i ist die Seitenansicht eines Fräsers gemäß der Erfindung; :11)1i. 2 bedeutet die Vorderansicht desselben.Fig. I is a side view of a milling cutter according to the invention; : 11) 1i. 2 means the front view of the same.

i ist die Welle, auf der der Fräsersatz angebracht ist. 2 ist eine über der Welle gelagerte Distanzbuchse, die gleichzeitig als Anschlag gegen zu @veites Ausschlagen der Fräsermesser dient. 3 sind zwei Flansche, welche die Fräsermesser tragen. 4 sind vier Schraubenbolzen, die zwischen den beiden Flanscheci 3 gelagert sind und die Fräsinesser halten. j ist eine Mutter, mittels derer der ganze Fräsersatz zusammengehalten wird. 6 sind vier Satz sägenblattähnlicli gezahnte Fräsmesser, die auf den Schraubbolzen 4 gelagert sind und durch die Distanzringe 7 gegenseitig versetzt nicht beweglich angeordnet sind. 7 sind zwischen jedem Fräsmesser gelagerte Distanzringe, damit eine gegenseitige Reibung der Fräsmesser vermieden wird.i is the shaft on which the cutter set is attached. 2 is a spacer bush mounted above the shaft, which also serves as a stop against excessive deflection of the cutter blades. 3 are two flanges that carry the cutter blades. 4 are four screw bolts that are mounted between the two flanges 3 and hold the milling machine. j is a nut that holds the whole set of burrs together. 6 are four sets of saw-blade-like toothed milling cutters, which are mounted on the screw bolts 4 and are arranged so as to be mutually offset by the spacer rings 7 and cannot be moved. 7 there are spacer rings between each cutter so that mutual friction between the cutter is avoided.
