ELECTROSTATIC ABRASIVE PARTICLE COATING APPARATUS AND METHOD |
| 摘要 |
A method of applying particles to a backing having a make layer on one of the backing's opposed major surfaces. The method including the steps of: supporting the particles on a feeding member having a feeding surface such that the particles settle into one or more layers on the feeding surface; the feeding surface and the backing being arranged in a non-parallel manner; and translating the particles from the feeding surface to the backing and attaching the particles to the make layer by an electrostatic force. |

1. An apparatus comprising:
a vibratory feeder having a feeding surface; a conductive member opposing the feeding surface; a voltage potential charging the feeding surface generating an electrostatic field between the feeding surface and the conductive member; and a web path for guiding a web between the feeding surface and the conductive member. |
