Leather machine rubberized shaft wear

When processing large skins, pinch rubberized rollers of leather machines must provide a sufficiently uniform pressure along the entire length of the shaft, as the thickness of the skins can vary up to 8 mm and more. The distribution of additional pressure is also affected by the buckling of the pinch and knife shafts, thus, with the aisle width greater than 2 m, additional factors affecting the wear of the roller surface must be considered. The article presents the results of experimental research into the wear of rubberized rollers as employed under factory conditions.
