These"nuts"on"top"of"the"gapset"knobs"serve"2"purposes:"
"
a) With"the"nuts"just"tightened"until"they"are"just"touching"the"gapset"knobs"while"
the"gapset"is"set"in"between"1"&"15,"the"operator"can"now"adjust"the"fold"roll"
pressures"for"running"a"thinner"stock"than"20#"bond"such"as"Bible"paper,"etc."
"
b) If"the"operator"is"able"to"set"the"gapsets"t o "a "ga p s et "se tt in g"g re a te r"t h an"15,"the"
operator"can"just"turn"the"gapset"knob"counterHclockwise"until"it"contacts"this"
nut."The"operator"can"then"turn"the"knob"clockwise"until"a"gapset"setting"of"1."
The"fold"roll"pressure"for"this"roll"should"now"be"set"for"a"single"sheet"of"20#"
bond"paper."
"
8. Turn"all"of"the"gapset"knobs"back"to"1."It"is"recommended"that"you"check"the"fold"roll"pressures"
of"all"fold"rolls"by"using"1”"wide"strips"of"20#"bond"paper"ad"doing"the"pull"test."IF"the"fold"roll"
pressures"remained"the"same"with"all"gapset"knobs"set"at"1,"then"you"may"proceed"to"the"next"
step."If"the"fold"roll"pressures"do"n o t"fee l"co rr ec t,"it"w ill"be"necessary"to"repeat"steps"4"H"6"to"
properly"set"the"fold"roll"pressures.""
"
9. The"gapset"knob"caps"can"now"be"pressed"into"the"top"of"the"gapset"knobs."
"
10. The"gapset"calibration"is"now"complete."

Setting"of"Gapset"Knobs"for"the"operation"of"the"folder:"
Proper"setting"of"each"gapset"is"determined"by"the"least"amount"of"sheet"thicknesses"passing"
thru"each"nip"between"the"different"fold "rolls.""
For"instance,"if"you"are"folding"a"sheet"of"20#"bond,"and"the"least"amount"of"sheet"thicknesses"of"
passing"thru"the"#1,"#2"&"#3"rolls"was"1,"and"the"least"amount"of"sheet"thicknesses"of"passing"
thru"the"#4"was"2,"and"the"least"amoun t"of"she et"thick ne sses "of"pa ssing"th ru"#5 "wa s"4,"the n"yo u"
would"set"the"gapset"knobs"for"the"#1,"#2"&"#3"rolls"at"1,"the"#3"&"#4"rolls"at"2,"and"the"#5"roll""
at"4."
For"thicker"and"thinner"stocks"than"the"20#"bond,"set"the"gapsets"as"you"would"for"20#"bond."
a) If"you"notice"pressure"marks"or"sever"cracking"on"the"sheet,"reduce"the"amount"
of"fold"roll"pressure"of"the"proper"fold"roll"by"rotating"the"gapset"knob"
clockwise."
"
b) If"you"notice"that"the"sheet"is"stumblin g"a s "it"p a ss es "th r u "th e "fo ld "b a n k "o r"t h e"
fold"is"not"crisp/tight"enough,"increase"the "am o un t"of"fold "roll"pre ssu re"of"the"
proper"fold"roll"by"rotating"the"gapset"knobs"counterHclockwise."
