Roller Caliper Set up (870 only)
WARNING: DO NOT MAKE ROLLER
ADJUSTMENTS WITH THE FOLDER
RUNNING! Serious personal injury or
machine damage could result from tools,
fingers, hair or clothing being caught by rollers.
Always disconnect the power cord when
setting rollers. Never operate folder with any
guards or fold plates removed.
Adjustable calipers are used on the Medalist 870 to
obtain clean crisp folds on a variety of stock. The
proper amount of paper strips (of the same material
being folded) in each caliper will give the best grip for
a good fold. As the paper is folded, the thicknesses of
the paper passing between the rollers increases. The
number of paper strips placed in the calipers should
be equal to the minimum thickness of the paper pass-
ing between the rollers (tail end of the sheet).

To provide the proper clearance between rollers, 3/4"
wide paper strips are inserted into the calipers, (fig.
27). Simply press the caliper lever and insert the cor-
rect number of strips into the open gap. Put the same
number of strips into both sides of the folder. Do not
use folded or torn strips of paper (they may give false
readings). Illustration 4 diagrams the position of roll-
ers, fold plates, feed table, calipers and the correct
number of paper strips to be placed into the calipers
for a common "Z" fold.
The chart on page 16 shows the caliper and plate set
up for several common folds.
N O T I C E
Whenever the machine is not being used, put
chipboard into the roller calipers in place of
paper to prevent rollers from getting flat spots.
This is an operator controlled maintenance
function. Roller flat spots are NOT COVERED
under warranty.
