The German Wheel Peel Fixture is used to test adhesion and bond strength of tapes, adhesive backed films and foils, laminated release coatings, plastic and paper films according to DIN 53357.
This test method measures the force needed to separate the individual layers of the sample material. The rotating wheel design allows the fixture to keep the sample at a constant 90º degrees throughout the test. The sample is peeled from its base and samples must be flexible so they can be wrapped around the wheel.
Run a test:
The sample material is wrapped around the wheel, the end of the sample is folded back on itself for an adhesive free area, this end is secured in the upper grip. During the test the sample peels off the wheel and the peel strength is measured.
Peel grip diameter of wheel 90mm, 10 kN (packaging 1 grip)
Peel grip with a clamp to fix
Note: grip adapters are available to fit this fixture to any test machine
