The Schopper Type Folding Endurance Tester is designed to determine the ability of paper to withstand repeated bending, folding, and creasing. It is widely used to evaluate the durability and service life of paper under continuous flexing conditions.

The instrument allows testing of two specimens simultaneously, improving efficiency. Spring-loaded clamps apply a standard load of 1000 g during testing to ensure consistent and reliable results.

The tester is equipped with two six-figure impulse counters with hold facility. When the first specimen ruptures, the corresponding head stops automatically while the second continues running. The machine automatically switches off once the second specimen breaks. The front panel includes start and stop push buttons with a light indicator to show the motor’s on/off status. An aluminum sheet cover protects the unit from dust and contamination.

Two independently operating folding units enable faster and more efficient testing.
