Appeal 2007-1364
Application 10/437,576
6. The timing belt 93 is trained on a pulley 102 which presses the timing
belt 93 downwardly and against the cylinder circumference 97 during the
web cutting process (Stobb, col. 6, ll. 8-14).
7. A pulley is a sheave or wheel with a grooved rim. Merriam-Webster’s
Collegiate Dictionary 1007 (11th ed. 2005).
8. The groove of pulley 102 of Stobb must have a depth smaller than the
thickness of the timing belt 93 in order to provide the required pressure
against the belt, because if the pulley had a groove depth greater than the
thickness of the timing belt, the pulley would come in contact with the
cylinder surface before the belt.
9. Figures 6 and 7 of Stobb show enlarged side or sectional views of
conveyor belts of the timing belt type. Figure 6 illustrates an outer belt
66 which includes a recess 71 for receiving a knife blade or cutter.
Figure 7 illustrates an inner belt 67 which includes a cutter 68. Both
belts have the usual teeth or cogs 69 for moving the timing belts in
precise synchronization relative to each other (Stobb, col. 4, ll. 51-62)
10. The conveyor belt 93, illustrated in Figures 12 and 13 of Stobb, is a
timing belt, which includes recesses 94 that receive cutters 87 (Stobb,
col. 5, ll. 50-56).
11. In another embodiment of Stobb, conveyers are operated at a faster speed
than the speed of the web at the point of contact with the drum to pull
apart uncut portions of the web (Stobb, col. 4, ll. 13-19).
