Abstract

Frame saw blade with two rows of slots which have the same grid dimension and are arranged offset from one another in the longitudinal direction of the saw blade, the longitudinal extent of the slots being roughly arranged in the breadth direction of the saw blade and thus producing greater stiffening of the saw blade in the tooth zone without reducing the flexural rigidity about a breadth axis.

Description

Es sind Gattersägeblätter mit einer Schlitzreihe bekannt, die vorzugsweise im hinteren Bereich des Sägeblattes angeordnet sind. Die Länge dieser Schlitze in Breitenrichtung des Sägeblattes ist dadurch begrenzt, daß mit der Länge dieser Schlitze die Biegesteifigkeit des Sägeblattes um eine Achse in Breitenrichtung des Sägeblattes geschwächt wird, und zwar proportional mit der Länge dieser Schlitze.They are frame saw blades with a row of slots known, which is preferably in the rear of the Saw blade are arranged. The length of this Slots in the width direction of the saw blade limited by the length of this Slit the bending stiffness of the saw blade about an axis in the width direction of the saw blade is weakened, proportionally with the Length of these slots.

Andererseits kann die Steifheit des Sägeblattes dadurch vergrößert werden, daß möglichst große Bereiche der Sägeblattbreite durch Schlitze unterbrochen werden.On the other hand, the stiffness of the saw blade be enlarged by making them as large as possible Areas of the saw blade width through slots to be interrupted.

Der Erfindung liegt die Aufgabe zugrunde, ein Gattersägeblatt zu schaffen, das in einem möglichst großen Breitenbereich durch Schlitze unterbrochen ist, ohne die Biegesteifheit um eine Achse parallel zur Breitenrichtung zu verringern.The invention is based on the object Frame saw blade to create that in one if possible large width area interrupted by slots is parallel about an axis without the bending stiffness to decrease in width direction.

Das erfindungsgemäße Sägeblatt weist zwei Schlitzreihen auf, deren Längserstreckung etwa in Breitenrichtung des Sägeblattes liegt und die in Längsrichtung des Sägeblattes zueinander versetzt sind und deren sich gegenüberliegende Enden in einer Sonderausführung sich überlappen in Breitenrichtung des Sägeblattes.The saw blade according to the invention has two rows of slots on, the longitudinal extent of which approximately in the width direction of the saw blade and which is in the longitudinal direction of the Saw blade are offset from each other and their opposite ends in a special version overlap in the width direction of the saw blade.

Die einzige Figur stellt das erfindungsgemäße Sägeblatt (3) mit den vorderen Schlitzen (1) und den hinteren Schlitzen (2) dar, die in Längs­ richtung etwa um das halbe Teilungsmaß zueinander versetzt sind.The single figure shows the saw blade ( 3 ) according to the invention with the front slots ( 1 ) and the rear slots ( 2 ), which are offset in the longitudinal direction by about half the pitch.
