Abstract

Backup roll 10 is pressed against xerographic copy fuser roll 11 by cam 12 that lifts free end 13 of cradle arms 14 at appropriate times. The opposite end 15 of cradle arm 14 is pivoted by ball and socket connection 16. Spring 17 yields upon closing of roll 10 against roll 11 to limit the force generated between the rolls. The force between rolls 10 and 11 is adjusted with the rolls in their closed position, as shown, by turning screw threaded ball pivot member 18, until a clearance 19 between fixed pivot casing 20 and preload adjustment nut 21 is measured by a feeler gauge 22.
