摘要

A back cloth for printing cylinders (especially for offset machines), with an inelastic metal base (1) overlapping a structure (2) comprising a microporous, compressible elastomer interlayer, a woven reinforcing layer and an elastomeric outer layer (3), in which (3) consists of two elastomer layers (10, 11) with a diffusion-resistant barrier layer (12) between them.
