Vorrichtung zum Erzeugen von Vierkantbalken aus Baumstämmen

摘要

To produce square beams from tree trunks (13), a device is proposed in which a tree trunk (13) is first positioned by a centering device (4) such that the lengthwise axis (14) of the tree trunk (13) assumes essentially always the same stipulated position. The tree trunk (13) is then grasped by holders (11, 12) of a carriage (8) concentrically to the lengthwise axis (14), whereupon the centering device (4) is opened. Then the tree trunk (13) is guided through a band saw (5) and trimmed on the opposite sides, whereupon it is turned by 90° and the two other sides of the tree trunk (13) are trimmed.
