Appeal No. 1998-0853
Application No. 08/381,364
Bosse discloses a bag-making machine comprising a variable gearing arrangement which
causes the angular speed of a transfer drum for feeding handles T and reinforcement sheets B
onto a moving web 32 to be altered during rotation of the drum such that the peripheral speed
of the drum matches that of the moving web 32 at the point of transfer of a handle T and sheet
B to the web (see angular range * in Figure 1), is a mean angular speed over angular ranges "
and $, and is a compensating speed over other angular ranges so as to maintain the cycle of the
drum at a predetermined constant regardless of the speed of the moving web. As explained in
column 3, line 40, to column 4, line 13, Bosse's variable gearing arrangement permits the
apparatus to be used to make different sized bags with a single transfer drum. While Bosse
discloses a variable gearing arrangement which could be used in Schroth to achieve the
necessary variable angular speed at which the ribbon strips are transferred by the roll 4 from
the feed station 57 to the transferring station 59 to accommodate a difference between the speed
at which the ribbons are fed to the roll and the speed at which the web 22 travels, we find in
Bosse no suggestion to feed the ribbons to the roll at a speed which is different from that of the
moving web 22.
As the examiner's rejection of the claims under 35 U.S.C. § 103 rests in part on the
determination that it would have been obvious to feed the ribbons of Schroth at a speed which
is different from the speed of the web 22 and as we find in the applied references no suggestion
