Device for clamping flexible plates including a pivotable three-armed profiled strip

A device for gripping a flexible plate having beveled suspension legs comprising:

• a cylinder of a rotary printing press, said cylinder receiving the flexible plate;
• a fastening slit on said cylinder, said fastening slit adapted to receive the beveled suspension legs of the flexible plate;
• a cylinder groove in said cylinder, said cylinder groove extending in an axial direction of said cylinder and connected, in a radial direction of said cylinder, with said fastening slit;
• a pivotable three-armed profiled strip in said cylinder groove, said three-armed profiled strip including a first, power arm, a second, load arm and a third, seating arm;
• an air hose in said cylinder groove, said air hose being in engagement with said first, power arm to shift said first, power arm;
• at least one spring in said cylinder groove and positioned to resist said shifting of said first, power arm;
• a free end on said second, load arm, said free end of said second, load arm being engageable with a beveled suspension leg of a flexible plate inserted in said fastening slit;
• a bearing in said cylinder groove, said third, seating arm being supported in said bearing for pivotal movement of said three-armed pivotable strip in said cylinder groove;
• a wedge-shaped slit defined by a surface of said third, seating arm and said cylinder groove, said wedge-shaped slit defining a wedge angle, said wedge angle being changed during said pivotal movement of said three-armed profiled strip;
• and
• a roller located in said wedge-shaped slit and engageable with another beveled suspension leg of a flexible plate inserted in said fastening slit.
