摘要： A cylinder for clamping printing plates for photogravure printing wherein the cylinder has a longitudinal bore comprising at least one clamping spindle with a surface for receiving the printing plate ends said at least the clamping spindle runs on the radius of the surface of the cylinder, wherein in the clamping and closing position, the cylinder bore is closed. The clamping spindle is flattened on the inside and loosely supports a continuous cylindrical cup which is positioned in the axis radial in the clamped and locked position of the clamping spindle. There is a tension spring and ball disposed in a lateral bore of the clamping spindle for supporting the spindle with respect to the cylinder bore wall at the side which is opposite to the advancing side of the cylinder.
