Stahl Folder -- The Good Old Stahl Folder

You're watching one of our oldest folding machines complete a tri-fold brochure.

The paper is 80# Silk Cover weight.
Therefore in the first fold unit we are scoring the piece at the fold lines. (no folding is happening here, only scoring)
A score puts a crease in the paper. The crease or score allows for the paper to fold, WITHOUT cracking.

Try to fold a piece of paper that is cover weight and if you fold it across the heavy ink coverage, in most cases the fibers of the paper will show through the ink. THAT is cracking. And, we all know that crack is NOT good!

The paper then takes a left turn, and goes down the line into the second and final folding unit.
This is where the paper is folded into thirds. Now, these are not EQUAL thirds.
The first panel needs to be a bit shorter than the middle panel, and the last panel needs to cover the piece so that cover-panel is the largest panel.

This machine is running about 13,000 tri-folds per hour.

We use this Stahl machine to fold COVER-Weight stocks as the rollers are harder rollers.

This is one of our oldest machines. We think she's was born around 1990 and we rebuilt her in early 2000 and added the hard rollers in 2008.

Compared to some of the Stahls i've run over the years, the folder in your video is nearly new. That said, give me a Stahl over an MBO any day of the week
