Coil binding machines punch, insert a coil, and fold and trim the ends to bind 90-300 pages. Dual coil binders can be separate or all-in-one machines, while plastic comb and plastic coil binding machines offer easy editing and flat documents.
Coil binding machines bind documents by lining up pages, punching, inserting a coil, and then folding and trimming the coil ends. Also known as wire binders, coil binders are usually manually operated and capable of binding 90 to 300 pages. Coil binding machines are available with various comb diameters. The larger the diameter of the comb, the more pages the machine can bind. Spiral binding is one of the most common forms of binding technology and one used to bind notebooks in a spiral.
One type of coil binding machine is the dual coil binding machine. Double loop binding is accomplished by punching the pages, laying them in the wire element, and pulling a handle to close the wire. This type of coil binder is available in a 32-hole punch using smaller wire or a 21-hole punch using larger wire. Double-ring bound documents lay flat and the pages can be folded over 360 degrees.
Dual coil binders can be purchased as two separate machines, a punch press and a narrower coil binder. Alternatively, a binding system can have everything contained in one machine. Coil binders are most often used for low to medium volume binding in offices, schools, churches and print shops. Using separate coil binding machines for punching and wire locking allows for greater punching capacity for larger jobs.
Plastic comb binding machines are another common type of coil binding machine. With these coil binding machines, a comb is inserted into the machine and a handle spreads the comb open. The pages are perforated and overlapped on the comb. Then, one pull of the handle closes the comb.
This system also allows the document to lie flat as the pages are folded. It has the added benefit of easy document editing. Plastic comb binders are also available as separate machines, a hole punch and comb opener for larger jobs, or all-in-one binding systems for low to medium volume jobs.
The newest type of coil binding machine is the plastic coil binding machine. These coil binders work by punching pages, inserting the coil, and trimming the ends. Then, the bobbin is spun onto the document by a rotating roller. This type of coil binder also produces flat, foldable documents, and is available both as separate machines and as an all-in-one binding system.
