4. Setting"the"fold"roll"gap/pressure.""
Note:&The&proper&factory&calibration&of&the&gapsets&is&to&where&by&individually&pulling&on&each&
strip&of&paper&and&the&fold&rolls&just&starting&to&rotate.&&&
Not&enough&fold&roll&pressure&could&cause&the&folds&to&be&tight&and&not&provide&enough&
drive&for&the&sheets&to &flow &thro ug h&the &roll&ba nk .&
Too&much&fold&roll&pressure&can&cause&unnecessary&cracking,&especially&on&coated&
stocks,&and&could&cause&premature&w ear&of&the&fold&rolls.&

a) To"do"this,"gently"pull"on"the"strip"of"paper"on"the"operator"side"and"feel"the"
amount"of"pressure"the"fold"rolls"are"applying."

c) Now"that"you"have"initially"calibrated"the"fold"roll"pressures"on"the"op era tor"an d "
nonHoperator"sides,"you"must"go"back"and"check"the"pressures"on"each"strip"of"
paper"again"to"ensure"the"pressures"remained"the"same."You"may"have"to"
readjust"the"pre ssure "on "each "side "to"ensu re"th e"pro pe r"am o un t"of"fold "roll"
pressure"is"maintained."
