A comb binding machine is a device used to bind documents together using plastic combs. These machines create holes along the edge of the pages, allowing the combs to be inserted and securely hold the sheets in place. This method is popular for creating professional-looking reports, presentations, and manuals. Comb binding is versatile and can accommodate various paper sizes and thicknesses. The process is simple: users punch holes in the pages, place the comb on the machine, and then insert the pages. This binding style allows documents to lay flat when open, making it easy to read and flip through.
