The leather folding test machine is used to test the bending resistance of leather under continuous bending. The instrument is internationally used for a variety of light leather and its surface modification for bending performance evaluation of the instrument. At the same time can also be measured due to walking in the crease in the formation of the tendency of cracking, bending tester bending mechanism and the upper deflection tester is different, both complementary functions. It is also used to pre-treat samples prior to the determination of water vapor permeability - especially for the determination of upper materials for protective footwear. How to maintain the leather folding test machine ?There Can be divided into nine steps as follows: 1. Before the start should be in accordance with the provisions of the lubrication and lubrication methods to lubricate; 2. by the understanding of the structure of the testing machine professional and technical pe...
