19. Check that the Guide Rollers are correctly adjusted. The intent of the Guide Rollers is to
reduce drag caused by the plate feeding through the machine. This is achieved by the plate
running against these free moving bearings which are slightly in front of the Guide Roller
Bracket, and thereby reducing the surface contact with the face of the Guide Roller Bracket.
For plates with straight edges, the Guide Rollers should be slightly in front of the face of the
Guide Roller Bracket, by approximately 0.020” [0.5 mm].
For plates with concave edges (i.e. bevelling the inside diameter of a large disk) the Guide
Rollers will need to be set further back (in towards the machine).
For plates with convex edges (i.e. bevelling the outside diameter of a large disk) the Guide
Rollers will need to be set further forward (out from the machine).
To adjust the Guide Rollers, follow the procedure on the following page.
