Our latest review on paper folders is the Martin Yale paper folder line. We have tested various folders including the Model 1217. We have noticed that this folder does not fold heavy pound paper - particularly 68 pound. The in fed roller also wears out quickly and we had to replace it after folding a few cycles. However, this particular model functions very well for small cycles. For instance, you can fold about 7.000 sheets an hour (or 7.000 sheets a cycle).

We also ran the Intimus paper folder f80 on heavy duty stock paper. The folds on 68 pound paper were excellent. This machine was able to make all six folds (single, double, fold out, zig-zag, gate, and letter) without any problems. During this test, we used about 50 sheets at a time and compared with running 100 more sheets of paper, there was no difference. The only issue we had was realigning the inserting paper. Included with the folder are some weighted wheel magnets that are used to apply pressure to the end of the paper so as to keep the in fed signal down. That way, we ensured that as the stack of paper went down, the paper was still bei`ng fed. A nice feature on this folder is the start and stop button. Occasionally, we ran into trouble running the paper in and it was very convenient to stop the paper folder.
