GRAPHIC ARTS SLEEVE AND SUPPORT MANDREL

摘要

A graphic arts sleeve includes a multilayer curved plate and an elongated slide. The plate presents opposed end margins that cooperatively form a longitudinal seam. The plate includes an engravable layer and an inner layer cladded relative to one another, with the inner layer being located radially inward of the engravable layer. The slide extends along the seam and is fixed relative to the plate radially inward of the engravable layer. A filler is located at least partly within the seam to bridge the end margins of the engravable layer. The engravable layer and the filler cooperatively providing an outer sleeve surface, with at least part of the outer sleeve surface being continuous across the seam from one end margin to the other end margin. A method of fabricating the sleeve and a press mandrel for supporting the sleeve, as well as other types of sleeves, are also disclosed.
