Overview
Mecmesin's Page Pull Tester, formerly known as the Smithers Pira Booktester, enables the evaluation of the page adhesion quality of so-called perfect-bound books and magazines.
This dedicated product is quick and easy to use, and requires no compressed air or mains power supply so it can be used anywhere.
Page pull strength test
The binding endurance test determines the force required to pull a page from the spine of a book.
The adhesive joint strength is calculated in N/cm by dividing the peak force required to remove the page by the page height.
The test is applicable to books bound with adhesives such as hotmelts and emulsions including PUR (polyurethane), EVA (Ethylene Vinyl Acetate) and PVA (polyvinyl acetate).
Setting a performance specification for page pull strength is difficult without a standard method of measurement.
Using the Mecmesin Page Pull Tester, the following page pull strength values have been found to be a reliable measure of performance:
| Pull strength range | Binding performance |
|---|---|
| Below 5 N/cm | Unacceptable |
| 5 - 7.25 N/cm | Satisfactory |
| 7.25 - 9 N/cm | Good |
| Above 9 N/cm | Very good |
