The STERLING® COILMASTER JR. PLUS is an automatic, table top plastic spiral binding machine. It inserts plastic spiral from the first hole onwards, then cuts and crimps automatically. This tabletop unit is affordable and can bind books from 8 mm to 30 mm. Speeds of up to 600 books per hour can be attained. The new in-feed conveyor allows for in-line binding with a coil former.
This plastic coil binder can bind books of any pitch, with round or oval holes. The margins can be slim or wide, up to 3/8” / 9.5 mm, meaning that you can pull punch pins prior to punching, and center the sheet. It can bind books of any length between 4” / 102 mm and 14” / 356 mm— not just a couple of standard sizes. The criss-cross combs guide the coil from both the front and the rear ensuring stable coil insertion. The crimping knives create a ninety degree crimp.
The STERLING COILMASTER® JR. PLUS offers quick and easy set up and minimal table top space. Why bind plastic spiral books by hand when you can bind them quickly and easily with... The STERLING COILMASTER JR. PLUS?
The Sterling Coilmaster III is a complete, in-line, plastic coil binding machine. Plastic filament is fed into the Coilmaker from a spool. It forms plastic coil on a mandrel within the Coilmaker. The formed coils are automatically fed into the Coilmaster®, which spins the coil into the book from the first hole onwards. The coil is then cut and crimped automatically. One operator can create coil and bind books at speeds up to 700 books per hour at the same time.
The Sterling® Coilmaster III is a heavy duty automatic plastic spiral binder designed for high production. This machine binds books from 8 mm in diameter to 32 mm in diameter, and up to 50 mm in diameter with the optional thick book attachment. Spiral bind books as small as 4" X 4" up to calendars 17" long. The machine can also be modified to handle larger books such as art pads.
The Sterling® Coilmaster III Plastic Coil Inserter
The Coilmaster® III inserter is the only spiral binding machine with a patented spreading device that allows for binding books with head and foot margins of up to 3/16 of an inch (4.7mm). It is possible to choose the size of your margin. No matter what size the book is, the Coilmaster plastic spiral binding machine will allow you to center the hole pattern on the sheet. This is especially important on odd sized books.
Here the outside pins are pulled, prior to punching, to ensure that an attractive margin (the distance between the first hole and the head of the book or the last hole and the foot of the book) is produced. This is the time honored standard when binding for double loop wire. This can now be achieved in plastic spiral with the patented spreading device on the Sterling Coilmaster III.
All other automatic coil binders do not allow you to use a margin that is larger than the bridge (the distance between two holes). Therefore you must make sure that the sheet fits exactly between the pins of the die pattern you are using. If the sheet is too large and forces you to punch a partial hole you must trim the book down, or bind the book another way.
Since many books are not exactly 11 inches, or A4, this becomes a common occurrence. Since other machines force you to use a larger hole size than the Sterling® Coilmaster III, the result will be a thinner margin. This is the reason other manufacture's recommend an oval hole. The ease of spinning in the coil is the same with round or oval holes. Oval dies tend to be much more expensive.
The Coilmaster® binds books punched with standard dies. Use round holes or oval holes. Pick the pitch you want to work with: 4:1, 5:1, 6 mm center to center, 8 mm center to center, 3:1, 2.5:1 or any pitch imaginable.
The Thick Book Attachment allows for the binding of books up to 50 mm in diameter. This modification includes: A vibrating jogger, 3:1 or 2.5:1 combs (this clamps the book and guides the coil), and extra large knives. The Coilmaker can also be modified to have larger gaps put in the tracks of the conveyor and a larger blower.

Making plastic coil just prior to insertion puts an end to working with twisted and deformed coil or coil with an improper pitch. Freshly made coil binds books more easily than coil taken out of a box. Cut the filament to the exact size you need, when you need it and cut down on waste, excess, and on storage. The cost of manufacturing coil is significantly less expensive than buying it preformed.
The STERLING® COILMAKER forms high quality plastic coil from plastic filament. This is achieved through the use of three axles pressing the filament against the forming mandrel as the coil is formed. Other coil formers only use two axles to press against the mandrel. This can cause "wobble" and produce coil that is not uniformly round, especially on larger sizes. This technology is why most of the plastic coil in America is made on this machine. The patented conveyor system ensures sufficient cooling time to make the most uniform coil available. The coil cools while it is still straight instead of laying twisted in a box. The heating element is infinitely variable to compensate for the ambient temperature at any given location. Tooling for sizes up to 50 mm is available for The COILMAKER.
