31-23 MIT Folding Endurance Testers
With this machine, a pliable specimen is placed under a constant tension load. The specimen is then folded to an angle of 135° in either direction, at the rate of 175 double folds per minute until the specimen is severed at the crease. A variable folding rate option allows the operator to vary the folding rate between 20 and 175 double folds per minute.
