摘要： A cladless anilox sleeve mountable on a mandrel suitable for commercial use as an anilox roll in flexographic printing. The anilox sleeve of the present invention basically comprises a cylindrical body of a predetermined axial length, the cylindrical body having inner and outer cylindrical peripheral surfaces and end faces at opposite ends of the cylindrical body extending radially between the inner and outer cylindrical peripheral surfaces. The cylindrical body is formed substantially entirely of non-metallic material and without an exterior metallic cladding thereon. Each end face of the cylindrical body has a circular recess formed therein at a radial spacing from the inner and outer cylindrical peripheral surfaces, and a metal ring is secured in each circular recess to promote maintenance of cylindricality of the cylindrical body. Each metal ring extends axially beyond the respective end face for deterring damaging contact therewith.
