Abstract
An apparatus for preventing jams in a folder of a printing press includes a roller having vacuum holes to which vacuum pressure may be applied to attract the loosely constrained signature towards the roller. The signature will follow the curved path of the roller and be led away from a jam area of the printing press. When the printing press is running at normal operating speed (e.g., steady state), the vacuum is removed from the roller because the signatures will be guided by grippers and will then take a path through the printing press for further processing.
