How Many Segmented Glue Rollers?

When applying glue on the register table for a letter fold;
A minimum of three segmented glue rollers are required. 

Fig. A & B; Signature open, glue exposed.
Fig. C; Signature still open, glue exposed.
Fig. D; Although signature closes between rollers 4 & 5 a glue relief is still necessary to avoid flattening/squeezing of glue.*

Fold plates #1 & 3 should have adjustable fold plate nose pieces installed.

Our segmented rollers can be left in your folder even when you are not gluing. The rollers are made with the same materials used in our new and recovered buckle folder fold rollers. We continue to inspect the rollers throughout the process to insure that they are concentric and straight. Our larger core diameter maintains the concentricity and straightness. This provides you the same performance grip and durability as our new fold rollers!
