Abstract

1,198,863. Printing surfaces. MACLELLAN RUBBER Ltd. 22 July, 1968 [20 July, 1967], No. 33291/67. Heading B6C. [Also in Division F2] In a printing roller of the kind having a cylindrical core with a covering of rubber engraveable by cutting to a predetermined depth to provide the required printing pattern, an intermediate layer of a rubber-treated material is provided in the rubber covering and is spaced from the outer surface of the covering at a distance equal to the required engraving depth. As described, a metal or copolymer core 1 is first either rough-turned, varnished and coated with a thin layer of vulcanite, or is smoothed turned and an adhesive coating applied thereto. A thicker layer 2 of unvulcanized rubber, either natural or synthetic, or a mix of these which may include some plastics, is applied over the vulcanite layer or adhesive, the thickness and hardness of the layer 2 being selected in accordance with the required resilience of the finished roller. The layer 2 is now semi-cured and its surface ground to provide a smooth surface to which is applied a solution of unvulcanized rubber. An intermediate layer 3 of cotton canvas proofed with rubber is now spirally or circumferentially wound on the layer 2 and over this is applied the engraving rubber layer 4 of a thickness, usually 1/8-1/4 inch, corresponding to the depth of engraving. The whole roller is now bound with a strip of fabric and completely cured, after which the fabric is removed. The engraved parts can be formed by making incisions in the layer 4 to the depth of the layer and peeling off the parts forming the pattern. Where a surface is required having two depths of engraving, two additional layers 3, 4 may be added.
