Appeal No. 2002-1945
Application 09/452,072
DISCUSSION
As correctly pointed out by the examiner (see page 3 in the
answer), the admitted prior art net wrap material feeding
mechanism meets all of the limitations in claim 8 except for the
one requiring the wrap material stripper to be “in the form of a
row of bristles.” According to the appellants’ specification
(see pages 8 and 9), the bristles serve the dual purpose of (1)
acting as a stripper to prevent the wrap material from wrapping
around the adjacent feed roll and (2) entangling and holding the
free end of the wrap material so that it advantageously folds
back upon itself at the start of the next wrapping cycle. The
examiner’s reliance on Anthony to supply the acknowledged
deficiency in the admitted prior art is not well taken.
Anthony discloses a lint cleaner for removing leaf
particles, motes, grass, and bark from harvested cotton fiber.
The embodiment 10 shown in Figures 1 through 4 comprises
compression rollers 14, 16, 18, 20, a feed roller 22 and a feed
plate 24 for feeding fibers of lint cotton 25 onto a saw cylinder
26, a grid assembly 28 cooperating with the saw cylinder for
cleaning the cotton, and a doffing brush cylinder 30 having a
plurality of bristles 30a for removing the cleaned cotton from
the saw cylinder.
