ABSTRACT:
A printing sleeve for a flexographic printing process is prepared by spirally winding successive adhesive coated tapes onto a forming mandrel such that the outer tape covers the seam in the previous layer, providing heat to the thermoplastic adhesive layers at the initial contact point between two tapes, providing sufficient tension to ensure consolidation, and advancing the resultant printing sleeve off the mandrel by means of a drive belt.
