ROLL, SHEET ROLLED BODY MANUFACTURING METHOD AND SHEET TAKE-UP DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a rubber roll as a contact pressure roll to be used in taking up a sheet into a rolled body, having a lower friction coefficient and less aging effects. SOLUTION: The rubber roll has a diamond like carbon film formed on the surface. Its surface has a static friction coefficient of 0.3 or less and a hardness of 30-70 degrees.
