After attaching the drive gear, apply press force to all folding rollers, and check the following points.
• Rotate the folding rollers for one round, and check that there is uniform roller nip (surface hollowing
amount of rubber roller) in all directions (left, right, center) between all folding rollers.
• Make sure that gear engagement is ample, and the rollers rotate smoothly.
At this time, if the nip amount on the left and right differs between folding rollers, paper may slip.
• Roller nip
: 0.1 mm (0.004") (folding roller shaft distance: 35.9 mm (1.41"))
• Folding roller drive gear backlash: 0.1 to 0.2 mm (0.004" to 0.008") for above distance between folding
roller shafts
Check the gear backlash with the folding roller key removed.
Apply grease to the whole circumference of the drive gear. (Orelube G1650: Equivalent to NLGI #1)
(5) Attaching the regulated stopper
The regulated stopper helps prevent inference between teeth resulting from excess distance between the
drive gears (helical gears), maintaining proper engagement all the time, and regulating force in the thrust
direction imposed on the helical gear.
The regulated stopper is secured at the position indicated in the figure.
The regulated movement amount of each folding roller is as follows.
Idler roller
: 0.8 mm (0.03") (1.5
°
)
Folding roller 1 : 0.8 mm (0.03") (1.5
°
)
Folding roller 2 : 1.1 mm (0.04") (2
°
)
