A binding page pull test, also known as a page pull strength test, is a type of test commonly used in bookbinding and printing industries to measure the adhesive strength or binding strength of book pages or other printed materials. It involves applying a controlled force to a page or a group of pages, typically by using a specialized instrument or equipment, to assess the strength of the adhesive bond between the pages and the bookbinding or printing material.
The binding page pull test is performed by grasping a page or a group of pages near the bound edge and applying a steady and controlled force in a perpendicular direction to the plane of the page(s). The force is increased until the page(s) start to separate from the binding or printing material, and the maximum force required to cause the separation is recorded as the binding or page pull strength.
The binding page pull test is used to evaluate the quality and durability of bookbinding or printing methods, as well as the effectiveness of adhesives or binding materials used in the production of books, magazines, brochures, and other printed materials. It is an important test to ensure that printed materials are bound securely and can withstand normal handling and use without pages becoming loose or detached. Standards and specifications for binding page pull tests may vary depending on the industry and application, and specialized equipment may be used to perform the test in accordance with industry standards.
