摘　　要：如果在挤水、剖层及削匀操作中没有进行精确的监测和控制，那么皮革的有用切削面积及剖下的重量将会明显减少。有用的切削面积由如下因素决定，厚度分布特性、软硬程度、物理强度、颜色均一度、撕裂强度松面及粒面质量。由CSIRO研究中心研制的种新型厚度衡量仪可以实现对整张皮革的快速多点测量，使用该仪器和相应软件能够生成整张皮革的厚度图。将该仪器连接到电脑上时，厚度图可以迅速的反馈给机器的操作者，从而控制剖层和削匀操作过程中皮革的厚度在允许的范围内变动，并据此来调整机器。剖层机通过厚度图来控制剖层可提高产率，其原因有三，（1）更为精确的剖层，（2）增加剖下部分的重量，（3）减少削匀的量。减少削匀通常会增加面积，在某些情况下，剖层足够精确的部位无须削匀。省去削匀对皮革的一些特性非常有利，如：强度（尤其是腹部）、纹理、松面和手感，这些性能的改善将导致产率的提高。为了证明该仪器和软件的有效性，我们对在制革厂中使用该技术提高产率的结果进行了讨论。Substantial losses in usable cutting area and the drop-split weight can occur if samming,splitting and shaving operation are not closely monitored and controlled. Usable cutting area is determined by assessing factors including： compliance to thickness specifications,softness or hardness, physical strength colour uniformity,break,looseness and grain quality. A new thickness gauge,developed by CSIRO,can be used to rapidly make large numbers of measurements over whole hides The use of these measurements and purpose written software enables graphical whole hide thickness maps to be produced When the gauge is connected directly to a computer the thickness maps give immediate feedback to machine operators. The compliance to thickness specifications in splitting or shaving is shown together with variance from allowwable tolerances enabling adjustment of machines. Use of the thickness maps at splitting machines can result in increased yield through： ——More precise splitting; ——An increase in the weight of drop splits; A reduction in the amount of shaving required. Reduced shaving usually results in increased area In some caseswhere splitting is sufficiently accurate,shaving is unnecessary Elimination of shaving has been shown to have positive benefits in leather properties including：strength particularly in the belly areas veinines,looseness and general handle. These improvement in leather properies lead to an increase in cutting yield . In addition to demonstration of the gauge and software result from use of this technology in tanneries and consequent improvements in yield will be discussed.
