Abstract
A roll for friction feeding copy paper in the developer section of diazo copying machines is constructed by roughening its surface to a degree which provides an RMS value of 150 to 350 microinches, and then subjecting the thus roughened surface to a hard coat anodizing treatment.
Claims5
A developer feed roll for diazo photocopying machines comprising a roll having a surface of aluminum in which the RMS value of the roughness of the major portion of its surface is between 150 and 350 microinches and in which the thus roughened surface has been subjected to a hard coat anodizing treatment to provide an anodized layer of at least 0.0015 inches in thickness.
The process of making a developer feed roll for diazo photocopy machines comprising the steps of:
- sandblasting an aluminum tube to create a roughened surface whose roughness has an RMS value between 150 and 350 microinches;
- and
- thereafter applying to the roughened surface of the tube a hard coat anodizing treatment.
