A bookbinding device utilizes a needle and thread to stitch sections of signatures together, creating a durable text block prior to the application of a cover. This process, distinct from other binding methods like perfect binding or spiral binding, secures pages robustly, allowing the book to lay relatively flat when open. An example includes the Smyth sewing method, known for its strength and flexibility.
This method offers several advantages. It produces a strong, long-lasting binding capable of withstanding frequent use. The ability to lie relatively flat enhances readability and is particularly valuable for large-format publications or music scores. Historically, this technique represents a significant step in the evolution of bookbinding, preceding modern adhesive methods and enabling the creation of more complex and resilient books. The craft remains appreciated for its archival quality and aesthetic appeal.
