摘要:
A textile pull roll cover is disclosed which has an exterior side with desired frictional characteristics for engagement with an advancing textile web. On its opposite side, the pull roll cover is affixed to a cylindrical outer surface of a textile pull roll by a repositionable pressure sensitive adhesive disposed therebetween. A method for making a textile pull roll is disclosed, as well as a method for changing a pull roll cover using repositionable pressure sensitive adhesive.
