摘要

A roller 14 for use with a surface-scraping doctor blade to meter a fluid applied to an outer surface of the roller 14. The roller 14 has the following elements: a substantially cylindrical core 101 having a core surface; a coating 105 of a polymer material 102 on the core surface, the coating 105 having a predetermined thickness and having a predetermined percent by volume of substantially hard wear-resistant particles 103, the coating 105 also having a surface which is the outer surface of the roller 14; a plurality of cells 104 in the coating 105, each of the cells 104 having at least one cell wall oriented substantially perpendicular to the outer surface of the roller 14 and having an open end at the outer surface of the roller 14. A method for the manufacture of the roller 14 and a method for using the roller 14 are disclosed.
