ABSTRACT:
Scores between leading and trailing edges of an advancing sheet are opened as the sheet moves over score opening wheels having their rotating axis transverse to the path of the sheet. The wheels are moveable along a path transverse to the sheet path to align the wheels with respective one of the scores. Sections cut from the sheet move in a side by side relation over freely rotating wheels mounted on a bowed shaft to space side edges of the adjacent sections to prevent edge damage.
