Abstract: A paper scoring device is on a first rotatable shaft of a pair of rotatable parallel shafts with a cylindrical member on the second shaft with a circular scoring slot around the cylindrical member where the paper is fed between the rotatable shafts. A male scoring device has a cylindrical base member with a shoulder and a cylindrical sleeve threaded onto the base member forming an outwardly open cylindrical groove in which a cylindrical ring member fits and rotates freely. The cylindrical ring is a pair of plastic rings sandwiching a metal ring which extends outwardly past the surface of the plastic rings to form a scoring rib which interfits into the slot to score the paper.
