Abstract
A sharpening device for use with a continuous flexible band cutting blade. The sharpening device includes a pair of rotating abrasive wheels positioned on opposite sides of the cutting blade. The rotating wheels are mounted to a pivot plate on either side of a pivot point between the pivot plate and an assembly arm. The pivot plate is rotatable about the pivot point through the application of a pressure device to the pivot plate. By rotating about the pivot point, the pivot plate moves the abrasive wheels into contact with the cutting blade to facilitate sharpening. The assembly arm is fixed about its upstream end, while the downstream end is movable to adjust the position of the abrasive wheels.
Claims18
A sharpening device for a continuous flexible band cutting blade having a cutting edge formed by a first and a second side flank, the sharpening device comprising:
- a pivot plate pivotally mounted to a pivot point adjacent the cutting edge;
- a first rotatable abrasive wheel connected to the pivot plate upstream from the pivot point, the first rotatable abrasive wheel contacting the first side flank;
- a second rotatable abrasive wheel connected to the pivot plate downstream from the pivot point, the second rotatable abrasive wheel contacting the second side flank;
- and
- a pressure device connected to the pivot plate to selectively rotate the pivot plate about the pivot point such that the first and second abrasive wheels are forced into contact with the cutting blade.

- and
- an assembly arm having an upstream and a downstream end positioned on opposite sides of the cutting blade, the assembly arm connected to the pivot plate at the pivot point such that the pivot plate can pivot with respect to the assembly arm.
A sharpening device for a continuous flexible band cutting blade having a cutting edge formed by a first and a second side flank, the sharpening device comprising:
- an assembly arm having a fixed upstream end and a movable downstream end, the upstream end and the downstream end positioned on opposite sides of the cutting blade;
- a pivot plate movably mounted to the assembly arm at a pivot point between the upstream end and the downstream end of the assembly arm;
- a first rotatable abrasive wheel connected to the pivot plate upstream from the pivot point, the first rotatable abrasive wheel contacting the first side flank;
- a second rotatable abrasive wheel connected to the pivot plate downstream from the pivot point, the second rotatable abrasive wheel contacting the second side flank;
- a pressure device connected to the pivot plate to selectively rotate the pivot plate about the pivot point such that the first and second abrasive wheels are forced into contact with the cutting blade;
- and
- an adjustment means for moving the downstream end of the assembly arm, the adjustment means being securely connected to the downstream end of the assembly arm.
