Method of producing a compressible layer and a blanket for printing

Abstract

An improved method of producing a compressible layer to be utilized for a blanket for printing operation is disclosed, wherein the improvements are that the method comprises the steps of adding to elastomer compound of oil resistant polymer pulverized material which is dissolvable in effluent, placing the elastomer compound over a base fabric in the form of a layered structure, and subjecting to vulcanization and then immersing it in the effluent at a predetermined temperature for a certain period of time. To improve compressibility one or more another compressible layers are preferably placed over the early prepared compressible layer with adhesive agent interposed therebetween so as to form an integrated structure. In addition, a method of producing a compressible blanket for printing operation is also disclosed according to another aspect to the invention, wherein after completion of producing the compressible layer, it is coated with adhesive agent at a predetermined rate of coverage in such a manner as to allow it to penetrate into a number of voids in the compressible layer and a reinforcing material is then placed over the compressible layer so as to adhesively integrate each other.
