20090114347 | Embossing Roller And Method For The Manufacturing Thereof - A method for obtaining an incision in an embossing roller using a hob, with a low-cost technique that enables protuberances 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 is obtained by machining the cylindrical surface of the roller 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 FIG. | 05-07-2009 |
