Abstract
The apparatus for testing the sharpness of a blade is arranged with a tape extending between a feeder spool and a receiver spool. The apparatus applies tension to the tape, and has a carriage arranged to bring the blade into contact with a stretch of the tape. The blade progressively makes a long-ways cut in the tape and, as it does, a measuring device detects the amount of force exerted for the cut to occur to determine whether the blade is sharp. A clamp locks the stretch of tape when in a straight line for contact with the blade, and has a main opening through which the tape moves longitudinally when driven between the spools A guide is arranged to help keep the stretch of tape in the straight line and has a main opening through which the tape moves longitudinally when driven between the feeder and receiver spools.
