Abstract

Eine Schneideeinrichtung umfaßt ein Bandsägeblatt (1, 1′; 21, 22; 25, 26, 29) mit einem Rückenbereich (4, 4′; 29, 34) und einem stirnseitigen Zahnbereich (2, 2′; 31, 33), dessen Stärke geringer ist als die Bandstärke im Rückenbereich (4, 4′; 34). Der Querschnitt des Bandsägeblattes (1, 1′; 21, 22, 25, 26, 29) ist bezüglich der Mittelachse für einen Mittelschnitt symmetrisch ausgebildet. Zwischen dem Zahnbereich (2, 2′) und dem Rückenbereich (4, 4′, 29, 34) liegt ein Übergangsbereich (3, 3′), gegebenenfalls mit seitlichen konkaven Flanken, die innerhalb von gedachten Keilflächen liegen. Für das seitliche Abtrennen von Brettern von einem Kantholz weist das Bandsägeblatt (21, 22, 25, 26, 29) Zähne (31, 33) auf, die nur in eine Richtung abgeschrägt sind, sodaß die Zähne beim endlosen Bandsägeblatt zueinander konvergieren. Bei der Schneideeinrichtung sind die Zähne (31, 33) gegen das Schnittgut, z.B. das Kantholz (20), gerichtet. Ein abgetrenntes Brett (23, 24, 27, 28, 32) läuft beim Vorschub selbsttätig seitlich aus der Vorschubbahn. Die durch Schleifen oder Walzen hergestellte Querschnittsform umfaßt eine Hartmetallvergütung (Stelitauflage), die durch Schweißen aufgebracht ist. Der Schnitt führt zu einem Aufspalten des Schnittgutes in zwei Bretter, die berührungslos an den Zahnflanken und im Übergangsbereich vorbeilaufen. Die Schneideeinrichtung kann ferner über Führungskeile (12, 13, 30) im Anschluß an das Bandsägeblatt verfügen. A cutting device comprises a band saw blade (1, 1 '; 21, 22; 25, 26, 29) with a back area (4, 4'; 29, 34) and an end tooth area (2, 2 '; 31, 33), the Strength is less than the band thickness in the back area (4, 4 '; 34). The cross section of the band saw blade (1, 1 '; 21, 22, 25, 26, 29) is symmetrical with respect to the central axis for a central cut. Between the tooth area (2, 2 ') and the back area (4, 4', 29, 34) there is a transition area (3, 3 '), possibly with lateral concave flanks that lie within imaginary wedge surfaces. The band saw blade (21, 22, 25, 26, 29) has teeth (31, 33) which are only beveled in one direction so that the teeth in the endless band saw blade converge to one another for the lateral cutting of boards from a square timber. In the cutting device, the teeth (31, 33) are directed against the clippings, for example the squared timber (20). A separated board (23, 24, 27, 28, 32) automatically runs laterally out of the feed path during feed. The cross-sectional shape produced by grinding or rolling comprises a hard metal coating (Stelit coating), which is applied by welding. The cut results in the clippings being split into two boards, which run past the tooth flanks and in the transition area without contact. The cutting device can also have guide wedges (12, 13, 30) following the band saw blade.
