A steel web conveying roller, and a process for manufacturing such a roller.

摘要

A stainless steel roller for conveying a web has a surface (14) prepared by blasting the surface of the roller 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 (14) is finished with a grinding action for removing the peaks to produce plateaus (30) surrounded by interconnected channels (32). The interconnected channels of the surface allow air entrained between the roller surface (14) and a web to be vented through the channels while the web is in contact with the roller.
