Description
Stammholzes 3 zugekehrten Ende sitzt an der Welle 7 ein in der Länge einstellbarer Tastdorn 13, dessen Ende gegen die Stirnfläche des Stammholzes 3 zur Anlage gebracht werden kann. Dargestellt ist in dem Ausführungsbeispiel die Anordnung eines zweiten Schwenkarmes 14, der zusammen mit dem Schwenkarm 6 auf gleicher Schwenkachse 10 montiert ist und dem Schwenkarm 6 in einer durch die Mitte des Stammholzes 3 gelegten Fbene gegenüberliegt Beide Schwenkarme 6 und 14 sind durch eine Feder 15 gegenebander verspannt An den freien Enden der Schwenkarme 6 undTrunk 3 facing end sits on the shaft 7 a length adjustable mandrel 13, the end of which can be brought to the plant against the face of the trunk wood 3. Is shown in the embodiment the arrangement of a second pivot arm 14, which together with the pivot arm 6 on the same pivot axis 10 is mounted and the pivot arm 6 in one through the middle of the log 3 opposite plane. Both swivel arms 6 and 14 are opposed to each other by a spring 15 braced at the free ends of the pivot arms 6 and
14 sind Stützfüße 16, J7 angeordnet, die im Beispiel durch abgeschrägte Stützrollen gebildet werden, die mit festen Schrägflächen 18 u;id 19 an den freien Enden der Schwenkarme 6 und 14 fluchten, wobei die Schrägflächen 18,19 einen Winkel einschließen, dessen Scheitel zur Schwenkachse 10 zeigt Bei Ansetzen des Kantenfräsers 4 wird die Welle 7 in der Zeichnung von links nach rechts axial verschoben, bis der Tastdorn 13 gegen die Stirnfläche des Stammholzes 3 liegt Dabei gleiten die Schrägflächen 18 und 19 über die Kante des Stammholzes 3 an der Stirnfläche und spreizen c*:e beiden Schwenkarme 6 und 14 gegen die Wirkung der Feder 15, so daß sich die Schwenkarme 6,14 nach Art einer Schere öffnen, bis der Kantenfräser 4 im Bereich der mit einer Anfasung 5 zu versehenen Kante an der Stirnfläche des Stammholzes 3 liegt Die Spannung der Feder14 support feet 16, J7 are arranged, which in the example be formed by beveled support rollers with fixed beveled surfaces 18 u; id 19 at the free ends of the Swivel arms 6 and 14 are aligned, the inclined surfaces 18, 19 enclose an angle, the apex of which points to the pivot axis 10 when the edge milling cutter is applied 4, the shaft 7 is axially displaced in the drawing from left to right until the stylus 13 against the end face of the log 3 is located. The inclined surfaces 18 and 19 slide over the edge of the log 3 on the end face and spread c *: e two pivot arms 6 and 14 against the action of the spring 15, so that the pivot arms 6,14 in the manner of a pair of scissors open until the edge milling cutter 4 is in the area of the edge to be provided with a chamfer 5 on the end face of the trunk wood 3 lies The tension of the spring
15 sorgt danach für einen ausreichenden Andruck, um den Kantenfräser 4 wirksam werden zu lassen. Gleichzeitig erfüllt die Feder 15 eine Sicherheitsfunktion, denn sie ermöglicht das Ausweichen des Kantenfräsers 4 bei unvorhergesehenen Hindernissen. Infolge der Feder 15 folgt der Kantenfräser 4 exakt der Umfangskontur des Stammholzes 3 an der Stirnfläche und führt somit eine gleichbleibend breite Anfasung 5 aus.15 then ensures sufficient pressure to allow the edge milling cutter 4 to take effect. Simultaneously the spring 15 fulfills a safety function because it enables the edge milling cutter 4 to evade unforeseen obstacles. As a result of the spring 15, the edge milling cutter 4 exactly follows the circumferential contour of the Trunk wood 3 on the front surface and thus carries out a consistently wide chamfer 5.
