ABSTRACT:
A safety cutter blade for a rotary trimmer. The blade has a hub formed with a central opening for mounting it on the drive shaft of a rotary trimmer. Three equally angularly spaced cutting blades are formed integrally with the hub and extend outwardly from said hub. Each blade is formed with a convex rearwardly swept cutting edge which is tangential to the hub on one side of the cutting blade and a short straight forwardly swept cutting edge on the other side of each cutting blade. Either of these cutting edges is adapted to be the leading, or effective edge depending on the orientation of the blade on the drive shaft and the direction of rotation of the trimmer shaft. The safety blade is made of an elastomer reinforced with plastic fibers. A layer of coarse fabric made of threads of an organic polymer is embedded in the elastomer and intersects the cutting edges of the cutting blades.
