Appeal No. 96-1214
Application No. 08/065,182
The subject matter on appeal is directed to a coating device (claims 1-14) and
methods for coating a size-press roll, paper or board (claims 15-19). The coating
device comprises a large-diameter revolving coating bar supported in a cradle and
abutted against a moving base having a tubular shape, a hollow interior, a diameter of at
least of about 18 mm and grooves on the outer surface thereof. The coating bar is
structured and arranged to meter the coating agent onto the moving base. Additionally, the
device includes a coating agent chamber. The method comprises providing a large-
diameter revolving coating bar with open grooves, arranging the bar in a coating device,
supporting the bar in a cradle, loading the bar against a moving base and applying,
spreading and smoothing a coating agent on the moving base.
Appellants argue the claims in three groupings: (1) claims 1-7, 15-17 and 19 ;
(2) claims 8 and 18 and (3) claims 9-14. Claims 1, 8 and 9 are illustrative and read as
follows:
1. A coating device for coating a size-press roll, paper, board or a surface of a moving
object, comprising
a larger-diameter revolving coating bar resting against a moving base having a
machine width, said coating bar extending substantially along the machine width and
having a tubular shape, a hollow interior, a diameter of at least about 18 mm and grooves
on an outer surface thereof, said grooves opening in a direction toward said moving base,
