Abstract

Die Erfindung bezieht sich auf ein Verfahren zum teilen von Baumstämme in kleinere Holzstücke. Der einzelne Baumstamm durchläuft eine Kantholzerzeugungsmaschine (1), die dem Baumstamm vier flache, parallele Seiten beibringt. Dem Kantholz wird Eckausnehmungen (22) beigebracht, die die Aufgabe haben, ein Seitenbrett (12) abzugrenzen. Jede Eckausnehmung wird abgegrenzt durch wenigstens ein Paar im Winkel zu einander orientierten Planflächen. Das aus den Eckausnehmungen entfernte Holzmaterial wird zu Hackschnitzel verarbeitet. Die einzelne Eckausnehmung (22) wird zustande gebracht nur mit Hilfe von zwei abgetrennten Kreissägeblätter (z.B. 6", 7'), die im Winkel zu einander gestellt sind, um zwei flache, winkelgestellte Schnitte zu sägen, die zusammen eine Latte (10) vom Kantholz (3') abtrennen. Die Latten (10) werden einer von der Kantholzerzeugungsmaschine (1) getrennten Hackmaschine (2) zugeführt, in welcher dieselben in einer getrennten Stufe zu Hackschnitzel zerspant werden.

The invention relates to a method for dividing tree trunks into smaller pieces of wood. The individual tree trunk passes through a square timber production machine (1), which teaches the tree trunk four flat, parallel sides. Corner recesses (22) are made in the squared timber, which have the task of delimiting a side board (12). Each corner recess is delimited by at least one pair of plane surfaces oriented at an angle to one another. The wood material removed from the corner recesses is processed into wood chips. The single corner recess (22) is brought about only with the help of two separated circular saw blades (eg 6 ", 7 '), which are placed at an angle to each other to saw two flat, angled cuts, which together form a crossbar (10) from Separate the squared timber (3 ') The slats (10) are fed to a chopping machine (2) which is separate from the squared timber production machine (1) and in which they are cut into wood chips in a separate stage.
