摘要
The two-dimensional lattice work is formed by folding a first (1) and a second (2) system of struts, which are connected to each other in their crossing points (3). Further folding is carried out at an angle of between 10 deg and 80 deg relative to the struts in the first two system, in diagonally opposite crossing points (5,7,6,8), and in a zig-zag shape. The struts are positioned so that al crossing points located on the corners of squares. The struts mainly consist of metal or plastic wires, or a combination thereof. Folding is carried out by a pair of grooved rollers (6). The lattice work is for use as a core, connected to non-woven fabric, in a drainage element.
