Abstract
A gear folder comprising a gear folding cylinder, at least a pair of folding rollers, and spaced pressure mechanisms for maintaining a precut ribbon segment in position on the folding cylinder for accurate folding of the segment. A first pressure mechanism is positioned before the folding rollers and a second similar mechanism is located after the folding rollers. These pressure mechanisms have rotating, yieldable surfaces which contact the ribbon section which is to be folded. The rotational speeds of the pressure mechanisms are different from each other and from that of the gear folding cylinder to tension the ribbon section on the folding cylinder.
