Everything There Is To Know About Spiral Coil Video
Transcript :
Welcome to MyBinding video. This is everything you need to know about spiral coil. First, there are sizes ranging from a 6mm diameter all the way to 50mm. The smallest size can hold up to 30 pages and the largest can hold up to 444. A great benefit to spiral coil is that the pages lay flat. Better yet, they fold nicely back to back and the choices of color is one of the largest in any type of binding. Standard size coil has a 4:1 pitch, which is compliant with its respected hole punches. The standard length of each coil is 12 inches. Coil should always be longer than the pages you're binding. There are also custom lengths up to 36 inches. With the extra length on each end, you finish off your book with special wire cutting crimpers. Once you're done, you'll have yourself a spiral coil bound book. For more demos, reviews and how-to's, go to MyBinding.com.
