Belt abrading apparatus and method
|
Joseph R. Taylor Jr. |
Richlands, NC |
This belt sander creates an air cushion between belt and platen via holes in the idler roller which introduces air flow; the milled edges of the platen confines the air flow to run longitudinally beneath the belt. The air flow provides a flat surface, reduces friction, and also cools the belt.
An example has been seen, serial No. 1, with this patent number and "Auto Crafts Belt Grinder / Automotive Craftsman, Inc. / R. 2, Box 111 Richlands, NC 28574". |
