Appeal 2007-2107
Application 10/190,123
(3) Jackson teaches that it is generally more efficient to produce
and/or process material in wider webs but often more convenient to package,
ship, sell, and/or use the material in narrower rolls (Answer 4; see Jackson,
Abstract; and col. 1, ll. 13-21);
(4) Jackson teaches the problem of “wandering” which happens to
narrow webs when guided and under tension (col. 2, ll. 13-21);
(5) Jackson discloses a two-stage separation process to combat
“wandering” where the first stage involves a partial separation but leaves the
web portions connected to be handled as a full width web, and after
handling, processing, and transporting, complete separation occurs near the
winding station (Answer 4; see Jackson, col. 3, l. 59-col. 4, l. 19; and col. 6,
ll. 9-16);
(6) Jackson teaches that the web portions after the first stage
separation can be handled as a full width web, thus allowing conventional
apparatus to be employed but avoiding the handling and tensioning of each
of the web portions separately that can lead to wandering (Answer 4; see
Jackson, col. 6, ll. 40-53);
(7) Jackson teaches that other web processes can be done during the
period when the full width web is being guided and transported between the
first and second separation stages (col. 7, ll. 6-12);
(8) Jackson teaches various web materials can be employed, and the
“lines of weakness” that substantially separate the web portions can be slits
or other alternatives (col. 9, ll. 39-55; and col. 11, ll. 21-24); and
(9) Marco teaches carrier stock with weakened perforated lines to
facilitate severance (Answer 6; see Marco, col. 4, ll. 12-20).
