This Dynamic Punching unit is designed to work with paper without perforation in continuous line, in front of the new digital printers or devices that need the creation of horizontal and vertical perforation lines. The speed of the unit is controlled by a dancer. It has four independent vertical drilling wheels, it also has two cylinders for horizontal drilling.
Each cylinder is controlled separately, independently by reading an optical cell.
The drilling position is double, it is equipped with cylinders of variable size, from 11 "to 14", which allows to produce perforations on one side of position 1 and in position 2 to produce perforations on the other side independently. The horizontal perforating cylinders are either of the magnetic type for steel plates or of the conventional type with cutting plates, which are mounted on quick-change brackets. Vertical perforations for continuous drilling are made in a separate position on the input side of the unit and can be equipped with any number of perforator wheels; for selective vertical drilling the use of magnetic plates is recommended.
