Abstract: A plate cylinder for multiple mounting of flexographic printing plates is provided. The plate cylinder has an outer circumferential surface and a longitudinal axis. It comprises an adhesion layer attached to the plate cylinder, the adhesion layer comprising a carrier sheet with a mounting surface side facing the plate cylinder and an adhesion surface side facing radially outwards in relation to the longitudinal axis; and a plurality of adhesion elements. Each of these adhesion elements includes an elongated body extending radially outwards in relation to the longitudinal axis and an end face for attaching the printing plate by an adhesive bond, wherein the end faces of the adhesion elements form the adhesion surface side.
