Bei ungespannten, einfach oder doppelt gezahnten Sägeblättern von biconcavem Querschnitt kommt es häufig vor, dafs bei starkem Druck gegen das Arbeitsstück ein Klemmen in den Führungen eintritt, was eine starke Er-. hitzung und Abnutzung des Blattes zur Folge hat.For unclamped, single or double-toothed saw blades with a biconcave cross-section it often happens that if there is strong pressure against the workpiece, it jams in enters the guides, which is a strong er-. heat and wear and tear on the blade.

Um diesem Uebelstande abzuhelfen, wird das doppelt oder einfach gezahnte Sägeblatt a an einer Längsseite mit einer Nuth b bezw. bx von dreieckiger, Fig. 1, bezw. rechteckiger Form, Fig. 2, versehen, während die obere und untere Führung d einen den Nuthen entsprechenden Ansatz c bezw. C1 erhält, welcher in der Nuth beim Arbeiten des Blattes gleitet.To remedy this inconvenience, the double or single toothed saw blade a is respectively on one long side with a groove b. b x of triangular, Fig. 1, respectively. rectangular shape, Fig. 2, provided, while the upper and lower guide d bezw a corresponding approach to the Nuthen c . C 1 received, which slides in the groove while working the sheet.

Durch diese Construction kann die Krümmung der Führungen nach dem Blatte zu möglichst gering gemacht werden und ist die Verwendung: von Sägen mit geringerer Blattbreite möglich..This construction allows the curvature of the guides towards the blade to be as great as possible can be made small and the use: of saws with a smaller blade width is possible.

Claims (1)

Patent-Anspruch:Patent claim: Bei der nach Anspruch 1. des Patentes No. 43972 eingerichteten Führung für ungespannte Sägeblätter an einer Führungsbacke die Anordnung eines Ansatzes c bezw. C1, der in eine an der Längsseite des Sägeblattes angebrachte Nuth b bezw. bx greift, um bei zu starkem Drucke gegen das Arbeitsstück ein Klemmen und die damit verbundene starke Erhitzung und Abnutzung des Blattes zu verhüten. In the case of claim 1 of patent no. 43972 set up guide for unstressed saw blades on a guide jaw the arrangement of an approach c respectively. C 1 , which b respectively in a groove attached to the long side of the saw blade. b x intervenes in order to prevent jamming and the associated excessive heating and wear of the sheet when the pressure is too strong against the workpiece.
