The knowledge of spiral books binding (YO ring books, spiral books):
1. Also known as YO ring (from English WeO- Binding), O-shaped coil. Double coils are two strands of steel coils with pre-set size and specifications. 2. Common materials are divided into two types: sprayed steel coil and plastic coil. Usually a round hole or a square hole is punched on the left or upper side of the printed matter. 3. After the double loop is passed through, the YO loop binding machine is used to press and fix the entire binding process. After the coil is locked, no more pages can be added unless the coil is removed. 4. The double-coil binding cost is higher than the single-coil binding, of course, the binding effect is better and more durable. Using the double-coiled picture album, any page can be completely flattened when reading, which is very convenient for reading and querying. 5. Books with a thickness of less than 30mm, such as tool books, technical manuals, recipes (cookbooks), VIS manuals, and architectural atlases, are suitable for this binding method.Details below to print and produce Metal spiral cookbook :
