binding is one of the most popular types of binding used.
Because it is economical, durable, reusable, and easy to
use, plastic comb binding is well-suited for many
applications. Comb binders are frequently used by schools, offices and home use. Bound sheet capacity varies
between models. Books up to 40mm thick may be comb bound
(480 sheets of standard 80gsm paper) The plastic combs may
be re-opened to remove and/or insert pages.
Manual plastic comb binding begins by punching holes
into a wad of paper (sheet punching capacity vary
between models). A plastic binding comb is then inserted
into the machine and a handle is pulled to open the combs.
The holes in the paper are aligned with the open combs,
inserted over the "teeth" and the handle is released. This
causes the combs to close around the document and bind them
Some plastic comb binders
use a two-lever system. The plastic comb is inserted and
opened before the paper is punched. The paper is
aligned with the opened comb and inserted over the comb as each wad of
paper is punched. This eliminates double handling of
the paper and saves
Electric comb binding
machines are also available. They take the effort out of
manually punching the paper and are more time efficient than
manual comb binders. Electric binding machines are generally
used for high volume binding needs.
look for when choosing a plastic comb binding machine:
capacity - how many sheets it can punch at one time
capacity - how many sheets it can bind at one time
sizes accepted - Does the binder have punch cancellation
feature so it is able to bind sheets other than A4
Control - Does the binding machine have a margin control
Plastic comb binding can also allow the operator to insert and extract pages
easily without destroying the comb. These days plastic comb binding is generally
used for internal documents, documents which are very thick or where
presentation is not paramount. It is not as secure a bind as wire binding, nor
will the pages turn 360 degrees or lie flat because of the plastic spine
obstructing. The nature of the sharp plastic comb tends to rip into the pages,
hence not providing as secure a bind as other methods such as double loop wire
or plastic spiral binding.
