This 520 DP-, is designed to work with non-perforated paper in continuous line. The speed of the unit is controlled by a dancer. The document then passes the piercing section where the cross bones, and (optionally) vertical holes are added.
Designed to be connected to Digital Printers and integrated into “finishing on demand” applications: the Dynamic Perf. Are able to make cross and length dynamic perforations, variable on the sheet.
Each perforation is separately controlled independently by reading an optical cell.
The drilling position is doubled, is equipped with cylinders of variable size, from 11 "to 14", allowing to produce perforations on one side in position 1 and position 2 can produce perforations on the other side independently. The perforator cylinders are either horizontal magnetic type for steel plates or conventional type cutting pipe character, which are mounted in supports rapid change. Vertical perforations for continuous drilling is done in a separate position on the inlet side of the unit and can be equipped with any number of wheels drills, for drilling vertical selective recommended magnetic plates.
Each horizontal drilling is controlled separately by reading marks on the edge of the paper in a free field.
