FIELD: heat-and-mass transfer processes. SUBSTANCE: member has many holes distributed in accordance with preset pattern which preferably may be used in packings. Each hole of packing is confined by edges of each two neighboring strips of flat material. Edges are extending at some angle to each other and/or curvilinearly. Initial material consists of many strips interconnected by their ends, facing each other by abutting or overlapping. EFFECT: higher efficiency. 24 cl, 23 dwg
