YYT503 Schildknecht Flexing Tester
1. Purpose: The machine is suitable for repeated flexure resistance of coated fabrics, providing reference for improving fabrics. 2. Principle: Place a rectangular coated fabric strip around two opposite cylinders so that the specimen is cylindrical. One of the cylinders reciprocates along its axis, causing alternating compression and relaxation of the coated fabric cylinder, causing folding on the specimen. This folding of the coated fabric cylinder lasts until a predetermined number of cycl... -
