  • Publication number: 20070059470
    Abstract: The adhesive tapes (20) for sticking together printing blankets on a metallic retaining bar or metal rail during a printing process. The adhesive tapes are composed of at least one layer (25), a release liner, and of a melt pressure-sensitive adhesive layer (30) that is applied to said release liner layer on one side. Both sides of the release line layer (25) have the same or different release.
