Abstract
A folder is adapted to fold sheets. A drum having a circumferential surface is adapted to withdraw sheets from a stack or from an overlapping flow and feed the sheets to the folder. A creasing apparatus is operatively arranged with the drum and includes: a first creasing wheel which cooperates with the drum to crease the withdrawn sheets that are fed to the folder, and a tracing wheel positioned at least axis parallel with the first creasing wheel and running on the circumferential surface of the drum to maintain a constant distance between the first creasing wheel and the circumferential surface of the drum.

- a drum having a circumferential surface defining a groove, the drum adapted to withdraw sheets from a stack or from an overlapping flow and feeding the sheets to the folder;
- and
- a creasing apparatus operatively arranged with the drum and including:
- a first creasing wheel aligned with the groove in the circumferential surface of the drum to crease the withdrawn sheets that are fed to the folder, the creasing wheel defining a creasing wheel axis, and
- a tracing wheel offset laterally from the groove and running on the circumferential surface of the drum to maintain a constant distance between the first creasing wheel and the circumferential surface of the drum, the tracing wheel defining a tracing wheel axis that is parallel to the creasing wheel axis.
