Fastening flexible printing formes

A device for fastening flexible printing formes on a forme cylinder introduces the ends 3, 4 of the forme into the channel 2 essentially symmetrically at right angles, and holds them respectively against the side walls of the channel in recesses 16, 17. To this end spring means 18, 19 are provided on semicircular-section shaft segments 6, 7 mounted directly in a bore 8 of the channel, these spring means protruding radially outwards from their respective segments and having formed ends 20, 21 corresponding to formations of the plate ends so as to hold the latter in place. The segments can each be turned from one axial end to allow the plate ends to be inserted and withdrawn. This arrangement involves a simple mounting of the segments 6, 7, is symmetrical and hence independent of the direction of rotation and requires only a narrow gap 14.
