ABSTRACT:
A roller for conveying a web is manufactured by applying a layer of nickel to a steel roller and blasting the surface of the nickel layer with steel shot to create on the surface a deep texture with well rounded down features and sharp up features with peaks. The blasted surface is finished with a grinding action for removing the peaks to produce plateaus surrounded by interconnected channels. The interconnected channels of the surface allow air entrained between the roller surface and a web to be vented through the channels while the web is in contact with the roller.
