Abstract

Die Erfindung bezieht sich auf ein Verfahren zum Zerspanen von Holzstämmen (1) zu großflächigen Holzspänen, bei dem ein rotierender, mit parallel zu seiner Rotationsachse (3) ausgerichteten Schneidmessern (5) versehener Messerring (2) einerseits und eine Anzahl ebenfalls parallel zur Rotationsachse (3) des Messerringes (2) ausgerichteter Holzstämme (1) andererseits aufeinander zu bewegt und dabei die Holzstämme (1) zerspant werden. Die Erfindung bezieht sich außerdem auf eine Vorrichtung zum Ausführen dieses Verfahrens.The invention relates to a method for cutting logs (1). to large-scale wood chips, in which a rotating one with parallel to its axis of rotation (3) aligned cutting knives (5) provided knife ring (2) on the one hand and a number also parallel to the axis of rotation (3) of the knife ring (2) aligned logs (1) on the other hand moved towards each other and the Logs (1) are cut. The invention also relates to a Device for carrying out this method.

Bei einer Vorrichtung der vorgenannten Art ist vorgesehen, daß die auf die Holzstämme (1) gerichtete Bewegung des Messerringes (2) und/oder die auf den Messerring (2) gerichtete Bewegung der Holzstämme (1) zumindest während des Zerspanungsvorganges auf einer gekrümmten Bahn erfolgt.In a device of the aforementioned type it is provided that the on the logs (1) directed movement of the knife ring (2) and / or the knife ring (2) directed movement of the logs (1) at least during the machining process takes place on a curved path.

Damit wird erreicht, daß einzelne Spansektoren

gestaucht", andere hingegen gedehnt" werden, woraus sich ein größerer Anteil von Spänen mit innerhalb der vorgegebenen Toleranz liegender Qualität ergibt.

This ensures that individual chip sectors

compressed ", others are stretched ", which results in a larger proportion of chips with a quality lying within the specified tolerance.
