ABSTRACT:
A gap cover of arcuate cross section for covering the longitudinal channel in the cylinder of a printing press, the cover being dimensioned to bridge the gap and held in place by first and second fastening assemblies accommodated below the presented surface. The first fastening assembly includes an axially oriented hook and stirrup, while the second assembly includes a radially oriented shaft having a flat head of oblong profile forming a pair of wings. The cover has a recessed portion radially aligned with the latching element and containing an aperture of mating oblong profile bounded by land surfaces so that the head of the latching element may project therethrough, for locking engagement with the lands upon rotation through 90.degree. by a turning tool. The shaft of the latching element has an associated detent for snapping the head from its free position to its locking position and for securely holding it there until intentionally released by additional turning movement. Preferably the cover has a nominal radius of curvature which is smaller that the radius of the cylinder, and the fastening assemblies are located at a radius which requires manual pressing of the cover into a slightly flattened sprung position as a precondition to engagement.
