1 heads have been disposed along their predetermined position.
2 The remaining heads in front of the master shifter 64 are then
3 pushed to one side and will remain operative. Thereafter, tube
4 46 is expanded to lock the heads.

7 From our review of Miller we make the following findings of fact:
8 14. “[T]he invention relates to, but is not limited to, the positioning
9 of carriages of the type which hold shearing, scoring or creasing tools
10 in an array transverse to a longitudinally-moving web of paper,”
11 (Miller, col. 1, ll. 9-12).
12 15. In most of these systems, the limitation on speed is a result of
13 the inability of the drive member to move the respective
14 carriages bidirectionally simultaneously when repositioning
15 them. Rather, all carriages must usually be moved first in one
16 direction to position some of them, and thereafter in the
17 opposite direction to position the remainder, requiring a time-
18 consuming multi-step process.

22 16. “[I]f power is interrupted for any reason, the stored pulse counts
23 of all of the position sensors are lost, requiring time-consuming return
24 of all of the carriages to the reference position for recalibration of the
25 position sensors before positioning can be determined or repositioning
26 can occur.” (Miller, col. 1, l. 67-col. 2, l. 4).
27 17. Thus, with the band 36 driven unidirectionally with a
28 continuous motion, simultaneous activation of the clutch
29 assemblies 50 of any of the carriages 32 to engage the upper
30 portion 36a of the band will move such carriages in the same
31 direction simultaneously. Conversely, simultaneous activation
