Method for producing a seamless printing form and printing roller with flexible surface layer

摘要

The hollow space is: formed between the outer surface of the support structure (2) and the interior wall of the casting mold; laterally closed by ring element (3) mounted at the ends of the support structure; and tightly sealed by the outer surface of the tubular, closed support structure, the inner surface of the mold and the ring element. A hardened elastic silicone layer and foam like layer (8) are introduced into the hollow space by continuous bores (4) located in the ring element. - The silicone layer is uniformly distributed on the interior wall of the casting mold and a centrifugal force is generated by making the support structure rotates together with the casting mold. INDEPENDENT CLAIMS are included for: (1) a seamless printing form; and (2) a pressure roller with a seamless printing form.
