Application:

This machine applies to test the resistance to repeated flexing of the coated fabrics under low temperature. And provide a reference to improve the fabrics.

Principle:
A rectangular strip of coated fabric is mounted around two opposing cylinders so that the test piece takes a cylindrical form. One of the cylinders reciprocates along its axis, causing the coated-fabric cylinder to be alternately compressed and relaxed, thus inducing folds in the test piece. This folding of the coated-fabric cylinder is continued for either a pre-set number of cycles or until damage to the test piece is apparent.
