Abstract
A paper folder has folding rollers spring urged against the complementary rollers so the rollers touch at the nip when no paper is present. A light spring allows the rollers to open when a piece of paper is to be received therebetween; but, the light spring completely closes after a short movement to limit the gap between the rollers. A heavy spring allows further spacing of the rollers under great force. The resulting folder will fold a range of thicknesses of paper, and including groups of several sheets of paper, without adjustment of the rollers.
