General Information: Spiral Binding/Coil Binding and Wire Binding

Spiral Binding or Coil binding is a very popular book binding style for creating reports, documents, proposals and presentations. Spiral binding is known by a number of names including spiral coil, color coil, colorcoil, ez-coil, plastic coil, coilbind and plastikoil. Documents bound with spiral binding / coil binding have the ability to open flat on a desk and offer 360 degree rotation for note taking- a applicable binding for manuals and notebooks. Spiral Binding is durable and is an excellent choice for documents. Spiral binding / coil binding elements are readily available in many colors and sizes.

Spiral Binding / Coil Binding Hole Patterns:

See how it is made:



The common hole / punch pattern is 4:1 pitch (4 holes per 1") spiral binding; or sometimes referred to as 6mm. 4:1 means there are four holes per inch on the binding edge of the document. The holes / punch pattern for this style are usually either round or oval shaped. Elements for binding documents with 4:1 pitch spiral coil are available in sizes ranging from 6mm up to 50mm in diameter.  Allowing binding documents that are up to two inches.



Not as common as 4:1 pitch spiral / coil, some prefer to use 5:1 pitch (5 holes per 1") spiral binding / coil or referred to 5mm they interchange. With five holes per inch, 5:1 pitch spiral / coil is tightly bound and provides a cleaner appearance. The limiting factor with 5:1 or 5mm pitch is that it only binds up to 25mm- not a good choice for larger documents as they are more difficult to bind function as a document.



3:1 pitch (3 holes per 1") spiral binding / coil is less common. Designed for use with the hole pattern used in Wire Binding (twin loop, double loop) or with GBC Proclick. 3:1 pitch spiral coil is easier to use for large diameter books because there are less holes / punch patterns to run the spiral / coil through. Spiral binding elements for this hole pattern are available in sizes ranging from 6mm up to 50mm.



2.5:1 pitch coil is also known a 0.400 pitch spiral / coil and requires a hole / punch pattern that has 2.5 holes every inch along the binding edge. Most users choose this hole / punch pattern that is produced for 2:1 pitch Wire Binding. 2.5:1 spiral coil uses a larger gauge plastic filament diameter and is designed for binding larger documents. Spiral / coil in this pitch pattern are offered in diameters; 20mm thru 56mm.

Spiral Binding / Coil Binding Lengths:  An added benefit of spiral coil binding is that the supplies are available many lengths to match your binding edge. The standard 12" length is the most popular spiral binding for 11" documents. This spiral / coil is put into an eleven inch document and the excess length of coil is cut and crimped at each end of the book. Binderies and print shops often times choose spiral binding /coil in 36" lengths for the flexibility to bind various document sizes.

Spiral Binding / Coil Binding Colors:  Spiral / coil binding supplies are available in a variety of colors. Spiral / coil binding is a great choice that allows the customer to highlight / accent a document with a desired color.

Spiral Binding / Coil Binding Diameters:  Spiral binding / Coil binding elements are typically measured in millimeters (mm) with inches being a close estimate to the actual mm size (6mm is very close to 1/4" but not exactly). Spiral binding is available in sizes from 6mm [1/4"] thru 56mm depending on the pitch (hole spacing of the document) of spiral that you choose.

Spiral Binding / Coil Binding Equipment:  It requires three pieces of equipment for binding documents with spiral binding / coil binding. A paper punch is needed to punch the holes along the binding edge of the document. A spiral / coil inserter is required to spin the spiral / coil through the holes- although above 35mm it is done manually. To complete the process spiral / coil crimping pliers or a crimping machine  is needed to cut and crimp the spiral / coil ends.  This completes the document by trimming the ends and securing the spiral element in the document.

General Wire Binding Information:

Wire Binding is one of the most popular commercial book binding methods used in North America and is known by a number of different names including twin loop wire, wire-o, double loop wire, double-o, ring wire and wirebind. With this binding method, users insert their punched pages onto a U shaped element and then use a wire closer to squeeze the spine until it is round. Documents that are bound with wire binding will open completely flat on a desk and allow for 360 degree rotation of bound pages.

Pitches / Hole Patterns:  There are three common hole patterns used in Wire binding documents with double loop wire. Each hole pattern has specific sizes and applications where it is best suited. Here is a quick overview of the different options...

Wire 3:1 Pitch (3 Holes Per 1"): The three to one pitch hole pattern is most commonly used for wire binding small sized documents with double loop wire. Spines for wire binding are available in sizes between 3/16" and 9/16" in diameter. Three to one pitch wires are not available in sizes larger than 9/16". The size of the holes used with this wire binding pattern simply does not allow for larger spines to be produced. The hole pattern used for 3:1 pitch wire binding can use either square or round holes.

Wire 2:1 Pitch (2 Holes Per 1"): A two to one pitch / hole pattern is most commonly used for wire binding larger sized documents it can also be used for binding smaller diameter books. 2:1 pitch wire is most commonly found in sizes ranging from 5/8" up to 1-1/4". However, a couple of manufacturers make wire binding special small sized 2:1 pitch wire for binding documents as small as 1/4". The holes for this type of wire binding are normally rectangular but can sometimes be square or round depending on the manufacturer of the paper punching equipment that you use.

Wire Binding Process: Binding documents using the double loop wire binding involves just a few basic steps.


Put together the document including covers and measure the document overall thickness to determine the correct size of wire binding element.



Set up your wire binding machine so the holes are centered on your paper.



Divide your document into appropriate sections and punch it using your wire binding machine or modular multipurpose binding punch.



Place the pages of your document onto the U shaped wire binding elements by hanging them on it.



After carefully arranging the pages of the document over to the wire binding closer, engage the machine to squeeze the element together until the U shape becomes an O shape- usually with a lever action closer although there are pneumatic systems out there.

 Wire Binding (twin loop / double loop) EquipmentBinding documents with double loop / twin loop wire requires a binding machine including a wire closer. Low volume operators will often find a small less expensive manual wire binding machine that offers a manual hole punch and a built in wire closer to be adequate. Medium volume users will often require a wire binding machine with an electric punch that can or cannot include a wire closer, wire closer can always be separate. High volume wire binding users such as print shops, larger binderies,  and in-house printers will split the punching and final stages of the binding process (punching, hanging pages on the wire and closing the wire) wire in order to increase productivity. These users will often use a higher end heavy duty modular interchangeable die punch or an automated punching system along with either a manual or an electric wire closing machine.
