Plastic coil binding is quickly becoming the most popular type
of short-run book binding method. Many companies are upgrading
their plastic comb binding to plastic coil. The reason? Coil
is more functional, secure, and looks better. Coil is available
in a wide range of colors, and coil-bound book pages may be
rotated 360 degrees, and will lay flat. Coil is great for bound
media that is mailed because of its resiliency. If the binding
is bent in shipping, it will bounce back to its original shape.
There are three primary types of coil: 4:1, 5:1, and, 6mm.
4:1 means there are 4 holes punched in every inch of your
binding edge, 5:1 means there are 5 holes in every inch punched
and 6mm is somewhere between the two.
4:1 coil the most popular type of coil bind. Its
also very versatile. A 4:1 coil bind will allow you to bind
books as small as 10 pages, and as large as 1-1/2" thick.
6mm coil is one of the newer coil types. It will
bind the same-sized documents as the 4:1, but has a slightly
tighter hole pattern.
5:1 coil has been referred to as the nicest looking
coil because of its tight hole pattern. 5:1 coil can bind
a book as small as 10 pages and as large as 7/8".
#1: Punch the sheets for your books. Make sure your pages
are all the way against the back wall and completely flush
against the side guide. Don't try to punch more pages than
recommended for your machine.
#2: If you do not have an electric inserter, then manually
twist or roll your coil into the book. If you have an electric
inserter, manually insert the coil into the first few holes,
then use the feed wheel or roller to insert the coil.
#3: Make sure the red dot on your pliers is facing up. While
keeping the pliers flat and horizontal to your work table,
squeeze the pliers tight and without releasing, twist them
clockwise to crimp. Hint: The deeper you can get the coil
into the pliers the nicer the crimp will be.
