Abstract
Mesh cells ( ) for machine-made netting ( ) use pairs of mesh bars ( ) made from a continuous length of material and meet at a common coupler ( ). Such mesh bars ( ) have a lay with a common direction throughout the length of material. In a zig-zag pattern used in knitting machine-made netting ( ), the longitudinal axis of symmetry ( ) of mesh bars ( ) turns at each coupler ( ). Towing such mesh bars ( ) 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 ( ) of the mesh bars ( ). As water flows past the mesh bars ( ), the cross-sectional shapes of the mesh bars ( ) produce a net component of force that is oriented in a direction perpendicular to a combined drag component of force for the mesh bars ( ).
