POLYMERIC SLEEVE USED IN PRINTING BLANKET

摘要

The present invention relates to a printing blanket comprising an inner multilayer spiral wound polymeric sleeve, wherein the sleeve comprises between 2 and 5 layers that are affixed to one another with an adhesive, the winds overlayone another to form the multiple layers, the gap between adjacent edges of each ribbon are less than 0.5 cm (0.2 inches) apart as measured axially, the total sleeve thickness is between 0.007-0.015 cm (0.0028-0.0006 inches), and the layers are formed either from a single continuous ribbon or a plurality of continuous ribbons of polymeric material. The adjacent edges of the ribbon may alternately overlay axially in an amount such that relaxation during curing results in non-overlapping edges.
