  • Patent number: 9279164
    Abstract: In a manufacturing method (HV) for producing finished leather (FL) for covering components with leather, wherein the following process steps for treating a leather hide (LH) are performed on a raw hide (RH) as an initial product for producing the finished leather (FL) as an end product of the method: mechanical process steps in which the leather hide (LH) is treated using mechanical tools, and chemical process steps in which the leather hide is treated with chemicals, wherein both mechanical and chemical modes of action are combined in individual process steps, it is envisaged that, in a process step of retanning, synthetic and/or vegetable tanning materials, fattening agents, microencapsulated auxiliary agents based on ammonium, phosphate, phosphorus and the ester compounds thereof and natural additives based on rubber and milk products are used, and in a process step of reducing the thickness of the leather hide, the leather thickness of the leather hide (LH) is reduced by splitting and/or scraping witho

  • Publication number: 20120307969
    Abstract: In a testing device (10) for determining the quality of leather (9) in the production of leather, wherein the testing device (10) is formed for examining a quality category of the leather (9) and for delivering a quality value characterizing the leather (9) in regard to its quality category, the testing device (10) comprises screening means (16) for examining the homogeneity of the leather (9) auf, which may screen at least portions (22, 23, 24, 27, 29) of the leather (9) and which are formed for delivering screening data (D) to analysis means (19), and wherein there are formed analysis means (19) for comparing the screening data (D) with feature data typical for hide injuries or inhomogeneities, respectively, of the leather (9) and for classifying determined hide injuries of examined portions (22, 23, 24, 27, 29) of the leather (9) and wherein there are formed display means (20) for display the categorized hide injuries or quality value, respectively, of the leather (9), preferably per portion (22, 23, 24, 2
