ABSTRACT:
A paper web, which may be pinless, is slit into side-by-side web ribbons that are merged one on top of the other for simultaneous crosscutting into appropriate page lengths. One web ribbon wraps substantially about an angled turnbar to shift it into registry with the other web ribbon. Pressurized air may be provided to the turnbar assembly to reduce friction with the web ribbon. The other web ribbon is detoured via a takeup roller by an amount that is dictated by the circumference of the turnbar assembly. A driven roller in continuous contact with one of the web ribbons draws it toward a cross cutter. A slave roller is in slipping contact with the remaining web ribbon and draws it toward the same crosscutter to maintain registry between the ribbons. Three-up, four-up, and more-up variations are disclosed.
