Shot blasted web conveying roller |
摘要 |
A stainless steel roller for conveying a web has a surface 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 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.
