SETTING FOLD PLATES AND DEFLECTORS Continued….
Any time you are checking fold plates, be sure all of the fold rollers are together and NOT set for
any thickness of paper in the Baumsets.
1. All fold plates are set the same way. If the fold plate has a gear rack the gear to raise the
fold plate and the gear on the fold plate has a punch mark. The punch marks must line
up from the tooth gear to raise the fold plate and the mark on the matching tooth on the
fold plate rack. If both sides of the fold plate are not the same, the fold plate and the
deflector will be crooked. Now replace all plate rails in the reverse order you removed
them.
2. The plungers should be removed on fold plates and plates rails that have plungers.
Place the fold plate gauge with the rounded side up between the number one idler roll
and number two roll. One gauge should be about one and a quarter inches from the left
end of the roll and another gauge one and a quarter inches from the right end of the roll.
On the number two and four fold plate location, put a little grease on the gauges to hold
them against the roller so they don’t fall out.
3. Insert the number one fold plate assembly with the deflector up until the plate rests
against the plate gauges. Loosen the five ¼-20 bolts that fasten the bottom fold plate to
the top fold pan of the fold plate assembly. The top fold pan and the bottom fold plate
both should be touching both fold plate gauges. Now tighten the five ¼-20 bolts. Scribe a
line on the both of the plate rails against the back of the fold plate. Remove the two plate
gauges. Latch the fold plate in place, with (plunger, gears or latches on the outside of
the rail. The fold plate should be on the scribe line. If not, move the plate rail in or out
with the eccentrics on the plate rails. The pre-fab fold plates with latches on the side
have adjustment screws on bottom plate and can be adjusted in or out without loosening
the ¼-20 bolts.
4. Now loosen the four fold plate guide screws under the fold pan. Loosen the plate clamps
so nothing affects the fold plate assembly against the plate rails. Hold the fold plate
assembly back about an inch from the rolls and tap the four corners of the fold plate
assembly to see if the fold plate lays flat on the fold plates rails. If the front of the fold
plate assembly on the left side is high; (away from the plate rail) you have four options.
1. -You can raise the front eccentric on the left plate rail, which will also lower the back of
the left plate rail. 2. -You can lower the back plate rail eccentric, which will raise the front
of the plate rail. 3. -You can raise the right rear plate rail eccentric, which will lower the
right side of the fold plate assembly. Then the fold plate assembly will lay flat on the left
plate rail. 4.-You can lower the right front eccentric, and at the same time raise the right
rear of the right plate rail. Naturally this also allows the nose of the fold plate assembly
lay flat on the left rail. They can not all be right because they have a different effect on
the distance of the nose of the fold plate assembly to the fold roll above the nose of the
fold plate assembly. To determine the proper adjustment, insert the fold plate assembly
into its proper location. Use a feeler gauge the proper thickness and check the distance
between the nose of the fold plate assembly and the fold roll above fold plate assembly.
To find the proper space, see the charts in Appendix B or C, depending on the type of
fold pans your machine has. As an example, if there was .015 on the right side between
the fold plate assembly and the fold roll and .020 between the nose of the fold plate
assembly and the fold roll above it on the left side. You would raise the front eccentric on
the left plate rail if you were adjusting the number one plate in the parallel section. The
small amount you raise the left plate rail would probably make both
sides .015
