Abstract
Device for keeping a lower covering layer of a two-layer covering on the cylindrical surface of a printing-press cylinder, the two-layer covering also including an upper covering layer covering the keeping device for the lower covering layer, the keeping device for the lower covering layer comprises a keeper rod having a substantially circular cross section and extending along the length of the printing-press cylinder, the keeper rod being braced at one end and at two axially parallel contact locations against the printing-press cylinder so as to position the keeping device in register and in inherently stable condition in circumferential and lateral directions, and locking pins disposed on and distributed in register-maintaining positions along the length of the keeper rod, the locking pins having respective head ends with different length-to-width ratios in the cross section thereof, the head ends being in cooperative engagement in correspondingly shaped holes formed in the lower covering layer.
