Saddle Stitching is the way most booklets and magazines are bound - wire staples hold the piece together through the spine / centrefold. The machine gathers together the printed and folded sections in the right order, with or without a cover, and then drives the required number of wire stitches through the centerfold where they clench. The stitched product then passes into a trimmer where the three open edges are trimmed to the finished size. Saddle stitching lines may also be equipped with a compensating stacker which stacks a pre-set numbers of items, turning the pile as it does so to form an even pile.
A saddle-stitched product lies almost flat when opened. Saddle stitching is a good choice for binding documents of up to 64-80 pages, in multiples of 4, depending on the paper bulk. Products involving more pages or of very thick bulk demand some other type of binding such as perfect binding.
