Application of Schildknecht Flexing Tester

Schildknecht Flexing Tester is used to test the flexure and flexure resistance of coated fabric.

A rectangular coated fabric strip is placed around two opposite cylinders to make the sample cylindrical. One of the cylinders moves back and forth along its axis, causing the coated fabric cylinder to compress and relax alternately, causing folding on the sample. The folding of the coated fabric tube continues until the predetermined number of cycles or samples are significantly damaged.
