Binding doesn't get any simpler! It’s easy to see why the classic, conventional GBC CombBind is our best selling binding spine. Whether you want to produce functional, everyday manuals or bind internal reports, CombBind spines enable you to create stylish, editable documents up to A4 size quickly and efficiently. GBC plastic comb binding offers unparalleled flexibility when it comes to updating documents. You can add, replace or remove individual pages whenever required, saving you the time and expense of reproducing a whole document if you only want to update a single page. Simply remove the plastic spine, edit your pages and rebind the document on your machine. And the bound pages lie flat too which makes pages easy to turn and photocopying quick and simple. Whether you are a novice or expert binder, comb binding is an easy 4-step process that everyone can master. Simply: 1. Collate the pages you wish to bind. 2. Punch the document using an electric or manual comb binding machine. 3. Insert the document onto the comb teeth. 4. Complete the closing process: with all pages and your chosen covers placed securely on the comb, just close the binding mechanism to secure your document and the process is complete. GBC combs are available in a wide range of colours and in 14 different sizes, in both A5 and A4, enabling you to bind documents from 2 up to 450 pages. Choose from 6mm to 28mm combs which are available in a round format, or 32mm to 51mm combs which are oval in shape to accommodate larger, thicker documents.
