Post back to report if attention to these points does not result in an improved performance. This will result in a roller bounce for that gap, which is OK. In the case of uneven length legs from a prior fold, each gap should be set to the least number of stock thicknesses passing through that roller gap in the particular job, so as to achieve proper drive force into the next fold plate. This 'calibrates' the gap sets, which can now be used to set the gaps for the required number of stock thicknesses that will pass through that roller gap in the particular job.ģ.

After this is done, the numbered collars can each be set to 0 without altering the gap setting itself. Each fold roller gap needs to be set even from side to side with ONE sheet of stock in the gap sets without regard to the numbered collar position.Ģ. These last two are often ignored by inexperienced operators.ġ. this is accomplished with spacer washers. Each fold plate needs to have the spacing between the two halves even from side to side and front to back. Each fold plate needs to have the the lower part, called the pan, set square to the top part, and set at the middle of its range (unless there is particular reason to set it differently).ģ.

Variations from this can be made to compensate from some other source of trouble, but should be returned to squareness at the start of each job set up.Ģ. Each fold plate needs to have the paper stop set square to the witness marks on the top of the plate. In addition to being set squarely in the machine, there are at least 3 concerns about the fold plates:ġ. Let's go on to the fold plates and rollers. From your 2:56 PM post it sounds as though your side guide use is not the problem.
