The GW6000 numbering, perforating, top/bottom slitting and scoring machine runs 6,000 A4 sheets per hour. It is the most popular of the GW range. All GW models are single phase 240 Volt and all are designed to take either a single sheet from 60 gsm NCR up to 10 part NCR fan-apart glued sets or heavier board. You can ‘crash’ number the glued sets with the top copy numbered in red or black. With responding copies of a set crash numbered you know there is never a missing number as might occur when pre-numbered stock is collated. This model can take up to 2 numbering heads for a total of 20 numbers per sheet and can be upgradeable to the GW8000 or 12,000 series so it’s the best starting point.
