Abstract
A folding jaw cylinder having friction increasing elements for insuring that the fold is not withdrawn from the folding jaws during removal of the folding blade is disclosed. The folding jaw cylinder includes a fixed front folding edge and a movable folding jaw which together cooperate to form a folding slot into which a folding blade forces a plurality of sheets which are folded into a signature. The folding jaw carries suitable friction increasing elements and the folding slot is so structured that the folded sheets are retained in the slot while the folding blade is withdrawn.
