The fold rolls in your Baumfolder are the heart and muscle of your folding operation. Make sure these valuable investments are still able to give you the quality work that your customers demand. This simple procedure can let you verify the condition of your rolls which will give you confidence on that next job. To check this operation, lock out the power supply to the folder so it isn't started up while you have your hands in the folder.

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.
