ABSTRACT:
A quarter-folder operates at high speed by reducing the leading edge to leading edge distance between successive papers, and continuing to move the papers forward while urging the papers down between folding rolls. The folding rolls are obliquely disposed so that a tucking blade urges a portion of the paper between the rolls, and the angular disposition causes the paper to continue. A plurality of pairs of folding rolls receives a paper for complete folding. Retarding brush rollers will slow the folded paper to be received by a conventional creel.
