    Abstract: The gap (15) formed between the end portions (5) of a gravure printing plate (3) which is anchored in a groove (2) of a printing cylinder (1) on which the plate is mounted is covered with a sheet (6) which overlaps the end portions. The gap cavity (9) thus formed is then filled with a thermoplastic and/or hardenable material and when this has hardened the cover is removed.
