Application No. 10/143,209
concerned with web material alignment and maintenance of the central line of a web
material so that the difference between the length of the generatrices of the side edges
and the central line of the web material is very small.
We agree with the appellant that Wessman does not describe an adjustable web
folding system which adjust the position of the folding detour based on the sensing of a
physical characteristic of the web. Instead, the Wessman sensors measure the
presence of the edges of the web indicative of the alignment of the web. Based on this
measurement, the guide roll 3 of the detour 20 is adjusted so as to adjust the position of
the web so as to align the edges of the web (col 1, lines 33 to 34; col. 4, line 51 to col. 5,
line 5). Therefore, we will not sustain the examiner’s rejection of claim 1 and claims 2
to 9, 11, and 16 dependent thereon.
Claim 17 recites that there is a first force sensor for measuring the first force on
the web substrate, a second force sensor that measures a second force on the web
substrate and the first and second force forces are compared to produce a resultant
force. The folding detour is adjusted in relation to the resultant force. In regard to the
recitations in claim 17, the examiner states:
. . . The web detour 20 is adjusted by device 13 due to the magnitude of a
resultant force signal generated by regulating device (not shown; see
column 4, lines 51 to 61). The resultant force signal is a comparative
measurement of tension in the web 1 (i.e. if the tension in one edge of the
web is greater than the other then only one sensor 12 will generate a
signal) [answer at page 3].
