Patent ID: 7736570

Claim:
Tool for generating a microstructure on a surface, the tool comprising: a matrix with a negative of the microstructure to be generated; and a pressure roller assembly comprising a first pressure roller, the pressure roller assembly moveably driveable over the surface, the matrix being disposed around the pressure roller assembly for pressing the matrix onto the surface, in which: the pressure roller assembly and matrix are arranged so that, when a center of gravity of the pressure roller assembly is driven over the surface, the matrix executes a rolling movement between the first pressure roller and the surface, with the negative of the microstructure to be generated facing towards the surface, and a device for accelerating the curing of a curable material is coupled to the pressure roller assembly so that when the pressure roller assembly is driven over the surface the curing acceleration device moves along with the pressure roller assembly and the curing acceleration device acts on a part of the surface over which the pressure roller assembly has been driven.
