<p>The printing plate (01) is a thin sheet of e.g. aluminum with inwardly bent hooks (13,14) engaging in an undercut groove with a narrow entrance and a hollow cylindrical interior. The first end of the plate (03) has a sharp bend with an angle (alpha 1) of approximately 45 degrees. It fits over a sharp lip in the edge of the groove in the printing plate. The second end of the printing plate (04) has an angle (beta 1) of 90 degrees, and fits over a 90 degree edge of the groove, opposite the sharp lip. A spring pushes a clamping plate against the second hooked edge of the printing plate.</p> |
