DEVICE FOR EMBOSSING MATERIAL SURFACE (VERSIONS) AND METHOD OF EMBOSSING MASK ROTATION STABILISATION (VERSIONS) Russian patent published in 2008 - IPC D06C23/04 

FIELD: engines and pumps, textile, paper.

SUBSTANCE: described aerodynamic embossing devices use cylindrical rotary masks with air pikes arranged therein to direct air flow through the mask holes onto the material surface to be embossed. The said devices comprise also at least one mask stabiliser arranged in the said device so that to apply a force to the mask sufficient to reduce that gap between the material and the mask area facing the material in close proximity to the material during the mask revolution.

EFFECT: high quality of high-resolution embossed images, reduced amount of poor areas and high uniformity across embossed material width.
