Cortech GW CREASEMASTER PLUS 4600 CREASING SYSTEM - Manual (Page 36)

5.0 Idler Wheels/Perforating/Slitting
5.1 Idler Wheels
The Idler Wheels (rubber tires on the accessory holders) are used to stabilize the stock as
it passes over the boss wheel shaft, especially in the situation where a perf or slit are set
up. They should be positioned 1-1½ in/2.6-4.4 cm from the edges of the paper with a
minimum amount of contact pressure. Skewing of the stock can be adjusted slightly by
increasing/decreasing pressure.
Warning: exit tires and perf/boss wheels use setscrews to secure their
positions. When tightening setscrews, do not over-tighten them. This
may scar the metal shafts and inhibit the free sliding movement of the
feed tire hubs or perf/score/slit boss wheels.
