1. A machine that can process multicopy printed output into separate stacks
of copy and used carbon paper. It is normally done as an off-line activity and
may be combined with a burster that breaks the continuous forms at
the perforations to give separate sheets.
2. A machine associated with
card-based data processing systems that could separate a punched-card file into
its constituent parts, i.e. header cards, which were frequently reused, and
detail cards, which, once processed, were kept only for a short time. This
facility was sometimes built into the collating machine. See collator.
