Also known as Library Binding, side sewn case binding offers one of the strongest binding methods available. In the side sewing process, threads are sewn through the full bulk of the text block and endsheets 3/16” from the spine. This yields strength, durability and longevity superior to simply “gluing off” the signatures at the spine. Cloth reinforcement is applied to both endsheets prior to sewing, which further enhances strength and durability.

Children’s books, educational books and reference books are just a few products that benefit from the strength and durability of side-sewn case binding performed at Muscle Bound.
