Abstract
A compressible printing blanket and method of manufacture, in which the blanket has at least one base fabric layer, an elastomeric face, and an intermediate compressible layer. The compressible layer is formed of a microporous material having cavities with interconnected passages. The material is made by admixing particles of hydrated magnesium sulfate in an elastomeric matrix, creating a blowing effect, and leaching the particles from the matrix.
Claims17
A laminated printing blanket comprising at least one fabric base ply, a surface layer, and a compressible intermediate layer, said intermediate layer comprising an elastomeric matrix having interconnected cavities distributed therethrough.
The method of manufacturing a laminated compressible printing blanket comprising the steps of forming a compressible layer of elastomeric material having interconnected cavities, and incorporating said layer into additional layers to form a completed blanket.
