Abstract
In a typographic plate cylinder comprising a groove or gap (11) for assembly of a coating, which in turn comprises two flaps (211 and 211′), which, when bent and inserted into a groove or gap of the cylinder, form a gap in the coating; a completion element is provided comprising an elongated element (23) designed to be inserted and remain jammed in the gap, without projecting radially from the coating, so occluding the gap.

1-20. (canceled)
A method for producing a coating for a typographic cylinder, said coating comprising a hard layer (21), deposited on which is at least one top layer (22), said at least one top layer (22) defining with its own thickness two opposed edges (221 and 221′) when the coating is mounted on the typographic cylinder (1), said method being characterized in that it comprises a step in which at least one elongated element (23) is prearranged and attached like an appendage to one of said opposed edges (221, 221′) for at least a portion of the length of the edge itself, and in that it comprises a further step of assembly of the coating (2) on the typographic cylinder (1) by bending the two flaps (211 and 211′) of the hard layer (21) corresponding to said opposed edges (221 and 221′) in order to insert them into a longitudinal groove (11) in the typographic cylinder (1), so that said elongated element (23) will close the space that is formed between said two flaps.

A coating for a typographic cylinder, characterized in that it comprises a hard layer (21), deposited on which is at least one top layer (22), said at least one top layer defining with its own thickness two opposed edges (221 to 221′) when the coating is mounted on the typographic cylinder (1), said coating comprising an elongated element (23) attached like an appendage to one of said opposed edges (221 and/or 221′) for at least a portion of the length of the edge itself, and in that said elongated element (23) has a cross section adapted for jamming between said opposed edges (221 and 221′) when the coating is mounted on the typographic cylinder (1).
