    • Described herein is a method for obtaining an incision in an embossing roller using a hob, with a low-cost technique that enables protuberances P that are rounded on top to be obtained, which improve the quality of the embossed material and reduce the wear of the mechanical components of the embossing units. The shape of the protuberances (P) is obtained by machining the cylindrical surface of the roller (1) that is placed between the tailstocks of the lathe using a hob that has teeth, the profile of which in cross-sectional view is complementary to that of the cross section of the protuberances illustrated in Figure 6. Figure 6 shows schematically in cross-sectional view a portion of the surface of the roller with protuberances in the machining step and a portion of the hob (10) with the teeth (D) that are generating the grooves that define the side faces of the protuberances . As may be noted in Figure 6A, the grooves between the teeth of the hob have a profile that is curvilinear in a cross-sectinoal view. With a double pass othis taccording two different inclinations of the surface of the roller the protuberances of Figure 5 and 6 are generated.
    • 这里描述了一种使用滚刀获得压花辊中的切口的方法,其具有使得能够获得顶部圆顶的突出物P的低成本技术,这提高了压花材料的质量并降低了压花材料的磨损 压花单元的机械部件。 突起(P)的形状通过使用具有齿的滚刀来加工放置在车床的尾座之间的辊(1)的圆柱形表面而获得,其横截面图的轮廓与该齿轮的轮廓互补 图6示意性地示出了在加工步骤中具有突起的辊的表面的一部分的横截面图,以及具有齿(D)的滚刀(10)的一部分, 它们产生限定突起的侧面的凹槽。 如图6A中可以注意到的,滚刀的齿之间的凹槽具有在剖面图中曲线的轮廓。 根据两个不同的辊的表面倾斜度,双向通过,产生图5和6的突起。
