As you use your folder for a length of time, the ink from the printing can build up and cause the rollers to become slick and lose their grip. If you begin to have trouble holding a fold, raise the fold plate with the folder power locked off and the fold plate secure so it does not fall on your hand. Check the urethane section of the fold rollers to determine if this has happened. Use SURE WASH and clean the fold rollers. The difficulty to clean the rollers depends on the amount of nik on the rollers.

To check for wear, with power locked out so no one can start the folder, remove the fold plates. Insert serveral single strips of paper rolled by hand into the roll in a forward direction about half way. Have a single strip of the same paper in the Baum Sets. Now pull on each strip of paper (don't pull it all the way out). You should have the same tension on all the strips. There may be a very slight difference and still be OK. Put the fold plates back in their proper location.

Also check for gouges or nicks created by severe jam-ups or using a screwdriver to remove jams.

Slitting a center trim out on a Baum 2020

Slitting can be utilized on your 1320 folder to cut apart multiple jobs that are printed on the same page. You can use a single blade and anvil to slit between the jobs or take a trim out, sometimes called a gutter trim.

The instructions below are specifically for 1300s with 1-1/8" slitter shafts. Note that 7/8" shafts will require a different procedure specific to that machine.

Remove the slitter shafts by taking out the knurled knob screw on the left side of the folder (operator side). Hold both slitter shafts in place with the right hand (CAUTION - SHARP BLADES)  and remove the knurled knob from the right side of the folder (non operator side) and with both hands, lift up and toward you and place them is a safe work area.

***USE EXTRA CAUTION WHEN INSTALLING SLITTER BLADES. They are sharp and will cut you.***

Note there are multiple spacers of different thicknesses on the blade holder. These are for mounting multiple blades at incremental center distance on the same blade holder. This is helpful when taking out a center trim. When placing the blades on the holder, place sharp edge away from the center and the next blade. Space the blade apart the same amount of trim you want to remove using the sharp edges to measure, using spacers between them for proper distance from the other blade. Both beveled edges of the blades should point to the other blade. The blade holder should be mounted on the shaft so the rotation of the shaft will not loosen the locking screw. (1-1/8 shaft with screw together collars only.)

Place at least two pull-out tires on each side of the slitter blade holder. Also install two on the top and bottom slitter shafts. Use the scoring collars with the sharp edge toward the slitter blade on the bottom slitter shaft. Then install the brass ring with the groove for the wire stripper, and then install the second scoring collar with the sharp edge toward the sharp edge of the second blade (the sharp edge of the collars should be toward the other). Install two more tires on the bottom slitter shaft and top slitter shaft. Replace the slitter shafts in reverse order that you removed them.

With the slitter shaft assembly back in the machine, position the center trim slitting assembly on the shafts, locating them in the correct area to remove the trim out on the printed sheet you will be running. Leave the set screws toward you and tighten them in place so if you move the blades, you do not need to keep turning the handwheel. The wire furnished with the center stripper wraps around the brass collar in the groove and twisted together at the end and hangs toward the floor.

NEW from BAUM: Adjustable slitter shafts for the 714XLT and 714XA folders

BAUM has designed another new feature for the popular BAUM 714XLT and BAUM 714XA 1st station parallel folders that will further increase your capabilities with these already productive folding machines. BAUM has developed a new optional cartridge slitter shaft design that can be installed in place of the existing fixed center distance slitter shafts. The adjustable slitter shafts enable better scoring capabilities that could not be accomplished using the “Fixed” center distance shafts.

The new design includes adjustment points at both ends of the slitter shaft cartridge assembly using a ball driver tool provided with the assembly. A simple turn of the adjustment screw will open or close the center distance between the parallel shafts to enable micro adjustment for select scoring using scoring tooling designs offered by BAUM on larger floor model folding machines. The adjustment can also now enable Microperforating of sheets by adjusting the fine tooth blade depth into the paper stocks.

The new BAUM adjustable slitter shaft assembly can only be added to select BAUM 714 series folders. It cannot be added to 714 right angle folders.

The maximum sheet width is 14.00 (35.56cm) width. The maximum stock weight is limited to the acceptable “curl” from running the sheets through the folding rollers before reaching the adjustable slitter shaft assembly.

For heavier weight stocks that can curl due to the back-bending in the folding rollers, BAUM also has the UltraScore attachment for the 714XLT folders. This enables the sheet to be run straight through using just the main drive roller and the roller directly above to drive the sheet in the Ultrascore assembly. The same tooling used on the new 714 adjustable slitter shafts is also used on the Ultrascore attachment.

It is also very important when adding the new BAUM 714 Adjustable slitter shaft assembly that your folding rollers and deflectors on the fold plates are in their best condition. Be sure to check these items and contact your local BAUM representative or contract the BAUMFOLDER Parts department to update your machine to perform at its best.
