Surface with a Surface Structure for Contacting Printing Material, Machine for Processing Material and Method for Producing Areas with a Surface Structure

摘要

A surface, especially a galvanically molded transport cylinder sleeve, has a surface structure for contacting printing material, in particular sheets of paper. The surface structure includes first structural elevations spaced apart from each other by a minimum distance A1 and having a height B1 and second structural elevations spaced apart from each other by a minimum distance A2 and having a height B2 with B2B1. A ratio between the distances A1 and A2 ranges between 10:1 and 1:1. The surface has support areas for supporting the printing material. The printing material is prevented from contacting a planar horizontal surface between the support areas of first, higher structural elevations due to second, lower structural elevations with support areas thereof that are formed between the first, higher structural elevations. A machine for processing printing material and a method for producing areas with a surface structure, are also provided.
