摘要： A roller 10 for conveying a web 12 is characterized by a surface 14 prepared by blasting the surface of a base roller 16 with steel shot to create on the surface 14 a deep texture with well rounded down features 22 and sharp up features with peaks which are removed during a superfininshing step to form the final surface. Down features 22 of improved stainless steel and nickel web rollers have a depth in the range from 1000 microinches to about 2000 microinches. Improved aluminum web conveyance rollers of the invention have down feature 22 depths ranging from 1000 microinches to about 2500 microinches. Titanium web conveyance rollers of the invention have down feature 22 depths ranging from 500 microinches to about 2000 microinches. The blasted surface is finished with a grinding action for removing peaks 26 to produce plateaus 30 surrounded by interconnected channels 32 . The interconnected channels 32 of the surface 14 allow more of the air entrained between the roller surface and web 12 to be vented through channels 32 while web 12 is in contact with roller 10 thereby improving the tractive force of roller 10 relative to web 12 surface.
