1. Function and purpose 
- End sheet pasting:
- End sheets are often used in bookbinding. The machine can precisely apply glue to the end sheets and attach them to the appropriate parts of books, brochures, or other paper - based products. This helps to protect the inner pages and provides a more finished look to the binding.
- For example, in the production of hardcover books, the end sheets not only play a role in aesthetics but also in strengthening the binding structure.
- Paper inserting:
- Automatic End Sheet Pasting and Paper Inserting Machine can insert additional sheets such as flyleaves, inserts, or advertising pages into the bound products. In the case of magazines, it can insert advertising leaflets or special - topic inserts into the magazine pages in an orderly manner.
2. Working principle
- Conveyor system: The Automatic End Sheet Pasting and Paper Inserting Machine usually has a conveyor belt mechanism that transports the base materials (such as book blocks or partially bound products) to the working area. The speed and precision of the conveyor belt are crucial to ensure accurate pasting and inserting operations.
- Gluing unit:
- It contains a glue reservoir and a precise glue - applying device. The glue is dispensed evenly onto the end sheets according to pre - set parameters. Some machines use pneumatic or mechanical pressure systems to ensure that the glue is spread thinly and evenly.
- The type of glue can vary depending on the materials being bound. For example, for paper - to - paper binding, a water - based adhesive might be used, while for more durable bindings, a stronger, solvent - based glue could be considered.
 - Inserting mechanism:
- There is a paper - feeding unit that takes the papers to be inserted from a stack and feeds them into the correct position in the product. Sensors are often used to detect the position of the base material and the inserted papers to ensure accurate alignment.
- For example, optical sensors can identify the edges of the book block and trigger the inserting operation at the exact moment to ensure that the inserted papers are centered and properly placed.
3. Applications and industries
- Bookbinding industry: It is widely used in the production of various books, including textbooks, novels, and reference books. By automating the end - sheet pasting and paper - inserting processes, it can significantly increase production efficiency and product quality.
- Printing and packaging industry: In addition to books, it is also used for the production of brochures, catalogs, and high - end packaging boxes that require the insertion of product descriptions or promotional materials.
