When it comes to document binding, you need to use punch and bind equipment. The  binding machine may be well known by most customers. It is a professional document binding equipment and many users have some difficulty in choosing the right binding machine. Although some comb binding machines attach with convenient instructions, most of them do not. Many manuals even do not include the guide of capacity or diameter of the bound files. If the comb is too large, the bound text will look strange. If the comb is too small, the page may be torn and it will be difficult to turn the page. So how can we choose the best size fit?
