Loose-leaf binding is one of the simplest book binding methods, and is often used in printed products that require frequent content updates, such as technical manuals, training materials, and financial statements. The advantage is that the increase and decrease of the page is very convenient, and the flatness after opening is good; the disadvantage is that the margin occupied by the stapling area is large.
There are two types of loose-leaf and stud. The principle is as follows: first cut the page to the size of the specification, and punch out the binding hole of the appropriate size on the binding edge; then put the page on the iron ring of the binder, or screw the stud on the binding hole, so that fixed. Elastic ring binders include plastic binders and metal binders.
Stud type loose-leaf binding can adapt to the binding of very thick books. The disadvantage is that when adding or removing pages, the process is more complicated, and all must be disassembled and reinstalled.
Loose-leaf ordering is suitable for industrial product manuals, catalogs, manuals, etc.
