Perforation

 

Perforation is the process of punching very small holes into paper in a straight line to allow easy separation of two sections. Examples of perforated work can be found in cheque books, raffle tickets, coupons, entry forms and more.

 

There are different types of perforator blades used for different projects. The different options available for perforating are based on the number of teeth around the circumference of the blade and type of teeth the blade has. The teeth are the small raised edges used to punch tiny holes in paper. Different perforating blades have different amounts of teeth that punch different amounts of holes per inch. The more holes punched per inch, the easier the paper is to tear.

 

The actual teeth themselves can also vary between small fine pins, elongated small blades or larger circular punches.
