Overview of perforating blades
With slot perforation, the paper is cut in a series of slots. This makes fold formation much easier and reduces material stresses within the folded sheet. The air trapped during folding can escape, which avoids creases in the folded sheet.
Perforating blades are come with different slot lengths and distances between slots to suit the paper grade and fold type. They can be inserted in either the front mounted or rear mounted slitter shafts. Slot perforating blades with a large number of teeth (between 40 and 80) can be used for tear-off perforations. Dependent on blade specification, possible applications include calendars and mailings. They are generally used in the front mounted slitter shaft, where the movable upper slitter shaft can set the undercut to match the thickness of the broadsheet exactly.
With sequential timed perforation, the tearoff perforating blade is complemented by a timed perforating head on the mounted slitter shaft. This setup works against the slitting wheel on the lower slitter shaft. The control unit determines the timing of the stroke cycles and, as a result, the perforating length in the folded or mailing product.
Punch perforations are created using a rotating punch perforating knife and two dieplates. The punch perforating knife punches out pieces of paper along the perforation line. The fold quality is significantly improved by trapped air escaping. Consequently, punch perforations are ideal for cross folding large numbers of pages (32, 48 or 64 pages) or high grammages of paper.
Punch-perforated sheets are often turned into a book block in the perfect binder without milling. The signatures remain together and the superior sheet edge adhesion produces a more durable end product.
This MBO blade is made of standard steel (ss). Depending on your application, you can save cost, improve quality of cut, reduce interval between sharpening, as well as downtime of your machine by purchasing a blade made of a higher grade metal alloy. We offer blades made of three classes of metal alloys: standard tool steel (SS), high speed steel (HSS) and tungsten carbide (TC).
