Abstract (en)
The covering comprises woven layers joined by connecting threads. In each connecting point or repeating connection unit, at least one connection is irregularly-arranged relative to the others. A variety of patterns having departures from regularity is described. A connecting point or unit may e.g. depart from or be offset from, a regular diagonal line of connections. Successive sets of connections on diagonal lines, may be inclined at differing angles. Up to 20%, 30%, 50% and most especially 70% of the connections in repeating units, do not follow a regular pattern. The smallest repeating unit is formed by 24, 26, 28, 30, 40 or more warp threads. At most 5 or 7 connecting threads are used. The connecting threads run in the warp and/or weft direction. The woven pattern formed on the paper side, is advanced by weaving the connecting threads with the warps or wefts on that side. The paper-side weave is a base weave or drain, preferably a canvas weave. Connecting threads are arranged in pairs.
