Definitions

  • An object of the invention is to have a full line of particulates across the width of the blade as it is viewed approaching along the line D in Figure 8. With the abrasive features mentioned this will be obtained in about 90 percent of the blades. The remainder may have a few open spaces due to loss of particulates from the time of first placement on the part up to the time the part is made ready for use.
