Abstract
A method for positioning a sleeve on a printing-press cylinder includes providing a printing-press cylinder, a sleeve which is to be positioned on the printing-press cylinder, and a polyvinyl alcohol. The polyvinyl alcohol is applied to at least one of an outer surface of the printing-press cylinder and an inner surface of the sleeve. The sleeve is then pushed or pulled onto the printing-press cylinder such that the outer surface of the printing-press cylinder and the inner surface of the sleeve lie confrontingly opposed to one another.

A method for positioning a sleeve on a printing-press cylinder, comprising the steps of:
- providing a printing-press cylinder, a sleeve which is to be positioned on the printing-press cylinder, and a polyvinyl alcohol;
- applying the polyvinyl alcohol as a coating on at least one of an outer surface of the printing-press cylinder and an inner surface of the sleeve;
- pushing or pulling the sleeve onto the printing-press cylinder such that the outer surface of the printing-press cylinder and the inner surface of the sleeve lie confrontingly opposed one another after said step of pushing and pulling with the coating arranged therebetween.
A printing-press cylinder assembly of a printing press, comprising:
- a printing press cylinder having an outer surface;
- a sleeve having an inner surface, said sleeve positioned on said printing-press cylinder such that said outer surface of said printing-press cylinder confrontingly opposes said inner surface of said sleeve;
- and
- a coating based on a polyvinyl alcohol arranged between said outer surface of said printing-press cylinder and said inner surface of said sleeve, said coating being applied to at least one of said outer surface of said printing-press cylinder and said inner surface of said sleeve and improving adhesion of said sleeve on said printing-press cylinder.
