  • Patent number: 11986895
    Abstract: The invention relates to an arrangement for setting saw teeth on a saw band (4), the arrangement having a base (1) through which the saw band can slide. The base has a receiving device (6) for receiving a saw tooth setting device (8). The saw tooth setting device (8) can set saw teeth in one direction. The receiving device (6) can receive the saw tooth setting device (8) on both sides of the saw band, so that the saw tooth setting device (8) received on one side can set the saw teeth in one direction and so that the saw tooth setting device (8) received on the opposite side can set saw teeth in the opposite direction. This means that although only a simple saw tooth setting device (8) arranged to be able to set saw teeth in one direction is used, the device for setting saw teeth can set them in both directions.
