Saddle stitching process and operation points

With the continuous development of post-binding technology, saddle stitching, as a process for post-binding of books and periodicals, its binding speed and quality have also changed. Saddle stitching is to align the pages of the book with a sleeve method, add a cover sleeve to form a whole post, cut the coiled wire on the machine, cut it in through the crease of the book, and lock its bent feet , Bookbinding costs. The saddle stitching process is short, fast, convenient, and low cost. It can be flattened when reading the book, which is easy to read. It can be widely used in the binding of brochures, news materials, magazines, albums, posters, etc. The process flow is a collating page. → Stapling → Cutting → Packing. Below, based on many years of work experience, the author summarizes the main points of each process according to the process of riding nails, and I would like to share with you.

1. Collate

The collated pages will be folded from the middle one in sequence, and the cover will be placed on the top.

Books that are bound by saddle stitching should not be too thick, otherwise the wire cannot penetrate and the number of pages can only be up to 100 pages. Therefore, saddle-stitched books generally need no more than eight groups of pages. When adding pages to the storage bucket, you should try to arrange a stack of pages neatly to allow air to enter between the pages to avoid sticking during the next page due to long stacking time or static electricity, which will affect the startup speed. In addition, for book pages with uneven code steps in the previous process, when adding pages, the pages should be arranged evenly to avoid downtime in the production process and affect production speed and output. Sometimes due to dry weather and other reasons, static electricity will be generated between the pages of the book. At this time, you need to sprinkle some water around the pages or use a humidifier to humidify the static electricity. Pay attention to problems such as upside down, white pages and double sheets when adding cover.
