1.0 General
Operational setup of the folder is simple and quick. No compli-
cated procedures are involved. A simplified fold chart is promi-
nently displayed on the exit table. The chart corresponds to the
alphabetical letter settings on the fold table scales. See section
4.3 for an example of fold chart.The scales are calibrated in
both inch and metric graduations. The folder features a positive
drive system that requires minimal internal drive maintenance.
The exclusive bottom, air-assisted vacuum feed is engineered
for accuracy and consistency, and eliminates the need to fan
paper before folding. The angle of the feed table and the air-lift
design of the paper guides provides minimal drag on the bottom
sheet as it feeds into the folding rollers. More importantly, this
system ensures smudge-free folding of all paper stocks that fall
within machine parameters. The variable SCR speed control
allows you to customize the speed setting to each application.
Although your folder was thoroughly tested and precision
adjusted before shipment, mis-handling during shipment may
necessitate readjustment. We recommend checking these adjust-
ments before you attempt to operate the folder. See Sections 5.2
& 5.3 in this manual.

3.1 Installing The Fold Tables
Both fold tables are alike and can be used in either the
first/upper or second/lower folding position. Each fold table has
two pin slots on each side. One each to the left and right front
of both the open/folding end and the closed/deflector end. The
front slots, one on each side, are for location. The rear slots on
each side are for positioning. The fold tables are supported on
the machine by pins located on the left and right main frame.
The pin locations for the first/upper fold table are above the
upper accessory shaft and the tie rod. The pins for the
second/lower fold table are above the pump guard.
