To adjust the caliper:

1. Turn the CALIPER ADJUSTING KNOB (F) clockwise three or four turns to raise the THROW OFF WHEEL (B) away from the PULL OUT ROLL (C).
2. Turn the folder on.
3. CAUTION: BE SURE HANDS, TOOLS, CLOTHING, ETC., ARE CLEAR OF THE FOLDER.
4. Turn the CALIPER ADJUSTING KNOB (F) counterclockwise until the THROW OFF WHEEL (B) starts to swing back and forth or kicks off.
5. Turn the CALIPER ADJUSTING KNOB (F) clockwise 1/2 turn, and reset the caliper by pulling forward on the CALIPER THROW OFF LEVER (A).
6. Run the sheet through. If the caliper trips on one sheet, turn the CALIPER ADJUSTING KNOB (F) clockwise another 1/2 turn, until the sheet travels under the caliper without moving the THROW OFF WHEEL (B).

Spring tension on the PULL OUT BANDS (D) should be set to have a light, even pull. The LOCK NUTS (E) should be tight, so the tension does not change.

By watching the operation, one can tell quickly what amount of rise to use.

As these are intended to trap the air in the sheets, they should be set sufficiently close, but not to bind the sheets. Two small bronze castings are provided that mount on these guides at the tail of the sheet. 

When running soft, spongy stocks, the finger must be very lightly weighted, otherwise the stock is compressed at the tail and there is a variance in pile height between the front and the rear of the stock pile.

Turn the power on. Do not press any buttons until the power-up cycle is complete and the count screen appears. Then press the button to move the table off the overrun switch. Once the table has cleared the overrun switch release the toggle switch.

PROBLEM: In the sheet length plus gap mode (easy button off), the sheet length plus gap will not go below 150 (no decimal point), or it has 3 decimal points 0.8.5.

SOLUTION: This is not a problem; it just means the machine is in metric mode. To return to the standard mode, press the mode select button to enter the batch set mode, then press the hidden button shown below.

• There are (2) static bars (1) Power Pack and a mounting kit included with the Static Eliminator.
• One bar is to be mounted at the entry side of the fold rollers and the other at the exit side.
• The cables on the bars are inserted into the connections on the main power pack.
• The bars are to be mounted approximately no greater than 1 inch above the paper.
• The hardware kit consists of universal mounting brackets that must be bent to fit the folder. The universal bracket kit is used because there are so many different folders in the market. Note that there are different “C” brackets for the tiebars. This is also due to the wide variety of folders that this accessory is used on.
• Reference the pictures below to see proper positioning.

FK2001355/50                  ADDITIONAL SLITTER SHAFT ASSEMBLY

This is an additional Slitter Shaft Cartridge set for the Baum 20PFF and CFF. The purpose of having an additional set of slitter shafts is to allow you to leave the tooling to remain in place for faster set up from one job to another.

For example if you do a lot of tri-folded newsletters you can have a set of shafts with the two scores and pull out tires in place for running newsletters. All you have to do is remove the slitter shaft cartridge you are using and replace it with the one with the two scores and you are ready to finish setting up your job.  This saves you the time of adding or replacing tooling on jobs you run on a regular basis. Some customers have a number of these assemblies set up for a particular job and just select the proper set to use on that job.

This Slitter Shaft Cartridge comes with no additional tooling or pull out tires. You will probably need to purchase additional Score, Slit, or Perf Kits along with additional pull out tire assemblies depending on what the job is that you will be setting up on the extra set of slitter shafts.

1. Turn the pump on and set air to maximum.

2. Set the vacuum at 5″.

If you cannot obtain the proper vacuum or air, check the following: A) Clean the pump filters. B) Check hose connections from the pump to the folder, or check for blockage in hoses. C) Contact your local dealer for service.

3. The caliper assembly should be positioned 90 degrees relative to the feed table.

4. There are two holes in the air tube (front blow) on the caliper assembly. These holes should be pointed towards the scribe line on the feeder table below the caliper. When the air is turned on, the bottom sheet should be blown down to the sucker wheel. If not, adjust the blow tube.

5. If the paper is stumbling on the cut out for the sucker wheel or not feeding properly, disconnect the air hose from the folder.

–Line the front edge of the holes in the sucker wheel with the orange tab (the side you put the paper against). See Figure A.

–Lay a sheet of 20 lb. bond paper on the feed table to cover the first set of sucker wheel holes with the leading edge of the paper. Turn on the pump. (Not the folder)

–Turn the handwheel until the leading edge of the paper is past the orange tab. The vacuum should release when the leading edge of the paper is 1/8″ past the orange tab.

–If the paper does not release at 1/8″, A) Remove the feed table. Then B) Loosen the set screw in the sucker wheel feed block closest to the fold rolls 1/4 turn. Tighten the set screw farthest from the fold rolls 1/4 turn. NOTE: Make sure the feed block has a little rotational movement (1/32″). If not, loosen the screw. Now C) Repeat 1/4 turn adjustments until the 1/8″ setting is obtained.

6. If the sucker wheel doesn’t pick up the sheet, reverse the procedure of adjusting the set screws as explained in #5 above.

7. Make sure 1/8″ flat washer is NOT between the sucker wheel and the feed block.

8. Make sure the sucker feed block hole is not plugged.

If these items do not resolve the problem please contact your local dealer, or contact our Technical Support group at 1-800-543-6107.

The drive motor shutting off is the result of a mechanical bind or an electrical problem.

The first thing to check is to make certain the folder is setting level and that the fold pans are not rubbing the fold rolls.

If the above items are okay I would remove the non-operator side guard. Then remove the belt from the motor. Run the motor to see if it still shuts off. If the motor does shut off then you know it is a problem with the motor or switch and you need to call 1-800-543-6107 and ask for technical support.

If the motor does not shut off then you have a mechanical bind. In the older 714’s (serial numbers beginning with 82 thru 90) the bearings on the ends of the fold rollers need to be lubricated periodically with a lightweight oil. Also the gears that drive the feed table and the stacker also need to be lubricated with lightweight oil. These gears are located on the inside of the non-operator side frames between the feed table and the stacker.

Another item that could be causing the problem would be the slitter shaft thumb screw that tightens into the frame. This screw should only be into the frame a couple of threads. If it is tight it could cause a bind.

If these items do not resolve the problem please contact our Technical Support group at 1-800-543-6107.

PERFORATING

The Ultrafold can be used to perforate either the folded sheet (to assist in making a right-angle fold) or to perforate sheets delivered flat. Baumfolder supplies one standard 41-tooth perforator blade. Additional perforator blades are available throught the Baumfolder Parts Department at 1-800-543-6107.

The perforator blade should be mounted loosely to the blade holder with the retainer collar to give better support to the perforator blade. Always be sure that the flat side of the blade is against the blade holder. Loosen the brass-topped set screws in the perforator collar and blade holder before attempting to place them on the slitter shafts.

The perforating blade holder assembly is then slid onto the upper slitter shaft along with the necessary pull-out tire assemblies. Then tighten the screws holding the perforator blade to the blade holder, aligning the blade to the holder. This allows for free horizontal movement on the shaft.

Side the grooved perforator collar onto the lower slitter shaft along with the other pull-out tire assemblies. The flat side of the perforator blade should just touch the side of the groove in the perforator collar. See Figure 17.

Figure 17

The perforator collar and blade holder can be slid to the desired position on the slitter shaft, then lock the blade holder and perforator collar into position with the brass-tipped set screw.

The perforator stripper fits onto the slitter shaft bar in between or next to the perforating blade. (see Figure 18) This strips the paper off for delivery and prevents it from wrapping around the perforator blade.

Figure 18

SCORING

The Ultrafold can be used to score a sheet and deliver it flat, or to score a sheet after a fold or folds have been made.

To ensure accuracy in making right-angle folds, always score the sheet where the fold is to be made. This applies in all instances when a perforator cannot be used.

Attach the scoring blade loosely to the blade holder for mounting on the slitter shaft. Scoring blades can be mounted on either the upper or lower slitter shaft. Once on the shaft, tighten the screws, aligning both the blade and the collar. This allows free horizontal movement on the shaft. Scoring blades should be placed so that the fold will be made with rather than against the scoring, or, in a continuing direction to the pressure of the crease that has been applied by the scoring blade.

For a wide, well-rounded score, use the two steel scoring collars. (See Figure 19) Sharpness and the depth of the score can be controlled by regulating the distance the collars are placed away from the scoring blade.

Figure 19

The scoring collars can also be placed on either side of the rubber scoring collar. The two collars can be compressed against the rubber collar, causing the rubber to bulge up for a deeper score. (See Figure 20).

Figure 20

Due to the increase use of copy machines and laser copiers, it is becoming more and more difficult to do the Z fold and the Engineering fold on these folders.

If you are doing, or are planning to do, a large quantity of these folds you may want to slow down the feeder.
(Contact your dealer for service)

This can be accomplished by changing 2 pulleys and one belt that are located under the non-operator’s side guard.

The part numbers you need to order are:

• 267-139-01-00 72 tooth pulley
• 267-141-01-00 20 tooth pulley
• 24165 belt

• Square the guide with the fold rollers.
• Remove the number 1 fold plate (top fold plate).
• Take an 11 x 17 sheet of paper that is cut square and lay on feed table against one of the side guides.
• Hand feed the sheet into the folder and watch the sheet come out of the first set of rolls. Watch the sheet to see if it comes out square, or if one corner comes out before the other. If one corner comes out before the other you know you are not feeding square.
• Referencing the diagram above, loosen the rear locking screws on the back of the side guide, then push in the micro-adj. knob and rotate the back of the side guide in the direction that the back of the paper needs to move to square the side guide. Once you have moved the side guide retighten the rear locking screws.
• Repeat step 3 to see if the paper is now coming out square. If not repeat step 4 until side guide is square.
• When you get the side guide square then loosen the collar and rotate it until the micro-adj. knob falls back on to it then retighten the collar.
• Then align the other side guide to the first side guide using the square sheet of paper.

There are two things to check, both dealing with the top sensor (the sensor located right above where the paper feeds into the fold rolls):

1. The bottom of the sensor must be even with the bottom of the nip guard, which it is mounted to. If it is not even, loosen the screw in the sensor and reposition it.
2. Is the sensor lined up with the hole in the feed table? If it is not lined up, loosen the screw holding the sensor and adjust the sensor, remembering step 1 above.

Most Baumfolder machines can produce a wide range of folds, including letter folds, half folds, z-folds, accordion folds, gate folds, and more. The number of fold combinations available depends on the model. Refer to our Guide to the 8 Most Popular Folds or our 18 Most Popular Fold Examples for reference.

Tabletop folders are compact, lower-volume machines designed to sit on a workbench and are well-suited for offices or small print shops. Floor model folders are larger, higher-capacity machines built for production environments that require continuous, high-volume folding.

Paper size and weight capacity vary by model. Most machines handle standard bond and text-weight papers, while select models are designed to handle heavier cover stocks and digitally printed materials. Check the individual product page for specific size and weight specifications.

Yes. Many Baumfolder models support scoring, perforating, and slitting as add-on capabilities through accessory kits that mount directly to the slitter shafts. This is especially useful for self-mailers, reply cards, and booklets.
