(57) Abstract :
A woven papermaker fabric (31, 81) having a first woven fabric layer (32, 82) made of first threads (2, 4, 6 ... 24; 34 to 45; 84 to
96) and having a second woven fabric layer (33, 83) made of second threads (1, 3, 5 ... 23; 46 to 57, 97 to 109), the two woven
fabric layers being connected by binder threads formed by structural second threads (46 to 57, 98 to 109) at binder points and
having knuckles (58 to 69; 110) having peaks (71, 112) constituting a peak plane (74) parallel to a paper side plane (72,113), and
the first threads forming knuckles (73, 111) with concave inner bends, the points of which lying nearest to the paper side plane
(72, 113) constituting an inner plane (75, 114), wherein the tension of the first threads (2, 4, 6 ... 24; 84) extending transversely to
the binder threads is such that the peak plane (74) is nearer to the paper side plane (72,113) than the inner plane (75,114) thereby
causing lateral deflections of at least one of the first threads (34 to 45; 85 to 96).
