Abstract
A paper folding machine is improved by grooving the fold rollers. Grooves in the fold rollers extend along a curved path, from one end of the roller and terminating adjacent to the center of the roller. Complementary grooves extend from the opposite end of the roller towards the center of the roller. The surface of the roller is rubber or the like, and has a durometer hardness in the range of 65 to 72 Shore A. The grooves are shallow enough that the paper is not crimped or wrinkled by the grooves.
