Baumfolder Rebuilding a 200 – 700 series folder - Manual (Page 15)

APPENDIX A - Suggested Special Tools List
Reference Appendix B & C for the proper part numbers that relate to your folder.
Note: Any Folder built after the 700 series has bearings and straight studs instead of eccentrics
in most locations.
BENCH LEVEL - used to check the level of the folder. The position of the
folder is not as critical as a lath or a machining tool but does need to be level so
the rollers run true against the next roller. The bench level has a v-groove in the
base so it lays true on the roller. The locations to level the folder will be noted in
the instructions. Usually the cross-locations are the fold rollers on the fold section
and the feed wheel shaft on the feeder.
PROTRACTORHEAD - used to measure the degree of the number one roller in
relationship to the main drive roller. The protractor has a level attached. Set the
protractor at 95 degrees and center the bubble to get 5 degrees forward or 103
degrees with the bubble in the center to get 13 degrees. Without this setting, you
have no starting location to use the roll gauges.
ROLL GAUGE - used to measure the distance from one roll to the next where the
fold plates are located. If the distance is too narrow, the fold plate will rub the fold
rollers. If the space is too wide, the paper will go over the top of the fold plate or will
not fold properly.
PLATE GAUGES - used to align the top pan and the bottom plate of the fold plate assembly
PLUS measure the distance between the fold rollers and the fold plate assembly. This is
important to allow the sheet of paper to properly enter the fold plate assembly as well as to fold
properly.
DEFLECTOR GAUGE - used to set the proper distance between the fold roller and the
deflector. This is very important. If one side of the deflector is closer to the fold roller than
the other side, the signature you fold will score crooked or slit crooked. This is caused by
the difference the sheet travels on the right side in comparison to the travel on the left side.
The deflector gauges gets wider at the top as you go from section to the next section due to
the bulk of the folded signature.
LINING BAR - used to insure the bushing or bearing in the right frame is properly
lined with the bushing or bearing in the left frame. If the rollers or shafts are not lined
with both sides, the bearing or bushing will get hot and overload the electrical supply.
You also use the lining bar by coupling the reamer to the end of the lining bar to line
ream the bushing in the main drive bushing and/or the slitter shafts as well as any other
shaft that turns in both side frames.
REAMER - used to size the I.D. of the bushing to the journal of the roller and/or the shaft to be used.
In most instances an oilite bushing should be broached instead of reamed. Since we oil the
bushing and do not rely on the oil in the bushing, we suggest reaming the bushing with a
sharp reamer. The standard REAMERS are used in the slitter shafts and/or main drive rollers and
locations where the shaft doesn’t move except to rotate. The EXPANSION REAMERS are used in the
idler rollers where the I.D. is .502 thousands or .002 thousands over the standard reamer.
FEELER GAUGES - used in several locations during rebuilding the folder. In most instances, the
straight feeler gauge about 12 inches long will work very well. On the 700 series with the fabricated fold
plate a deflector is wider and you need a feeler gauge with a bend on the end, you may want to consider
buying one from BAUM to insure the correct setting.
