for the drive rollers 20 (see col. 5, ll. 59-63 and col. 7,
ll. 41-44) and the speed of rotation of the electrical motor
41 in dependence on the position of the carriage 40 and the
signals from the sensor 37 and the rotary sender 39 (see col.
8, ll.
20-24).
The examiner determined that Nyfeler teaches a “means
(34) [sic, (40)?] responsive to the first and second sensors
(37 and 38) for simultaneously adjusting by equal and opposite
amounts path lengths followed by the carrier (5) on the input
and output sides of the transfer station (11).” See answer,
p. 4. In support, the examiner cites the following disclosure
at col. 8, ll. 2-8 of Nyfeler (answer, p. 8):
Movement of the carriage 40 in the forward feed
direction 8 or in opposite relationship thereto
increases the speed of the backing strip 5 in the
sticking plane 18 relative to the strip speed B or
reduces it, or reverses it, in other words the
backing strip 5 is pulled back by a predetermined
length in opposite relationship to the forward feed
direction 8.
In our opinion, the examiner’s position that movement of
Nyfeler’s carriage 40 between first 44 and second 45 reversal
