Abstract: A device for testing sharpness value of a cutting edge which includes an elongated body of a material into which a properly sharpened edge only will bite when lightly slid therealong at a predetermined angle. A sharply angled ridge is provided at at least one end of the body of the device and may be lightly drawn and/or pushed along the cutting edge to check for nicks or other imperfections in the edge. The edge tester is preferably of unitary construction, with a test ridge at both ends, and manufactured of a polymeric material. A method of testing the cutting edge is also disclosed and claimed.

Abstract: Method and apparatus for coating a moving porous web with viscous coating material, particularly for coating bias-cut, woven fabric with a tacky neoprene composition, to fill the interstices and uniformly coat the faces thereof, comprising a tenter frame for moving the fabric in a horizontal path of travel while maintaining it in dimensional stretched configuration. A pair of coating heads having opposed discharge manifolds positioned above and below the path of movement of the fabric on the tenter frame are supplied with viscous coating material which is applied to the moving fabric. The fabric is dried after each coating application and subsequently collected for use as reinforcement in the rubber cores of V-belt contructions.
