    • Mesh cells (30) for machine-made netting (51) use pairs of mesh bars (35) made from a continuous length of material and meet at a common coupler (34). Such mesh bars (35) have a lay with a common direction throughout the length of material. In a zig-zag pattern used in knitting machine-made netting (31), the longitudinal axis of symmetry (38) of mesh bars (35) turns at each coupler (34). Towing such mesh bars (35) causes water to flow past pairs thereof in two different directions with respect to their common lay. The directions of water flow are neither parallel nor perpendicular to the longitudinal axis of symmetry (38) of the mesh bars (35). As water flows past the mesh bars (35), the cross-sectional shapes of the mesh bars (35) produce a net component of force that is oriented in a direction perpendicular to a combined drag component of force for the mesh bars (35).
    • 用于机器制网(51)的网孔(30)使用由连续长度的材料制成的成对的网棒(35),并在公共耦合器(34)处相遇。 这种网格条(35)在整个材料长度上具有共同的方向。 在针织机网(31)中使用的锯齿形图案中,网杆(35)的纵向对称轴(38)在每个联接器(34)处转动。 牵引这样的网状物(35)使得水能够相对于其共同的铺设在两个不同的方向上流过其对。 水流的方向既不平行也不垂直于网杆(35)的纵向对称轴线(38)。 当水流过网格条(35)时,网格条(35)的横截面形状产生一个力的网分量,该网分量垂直于网格(35)的组合阻力分量的方向定向, 。
