<p>A macroscopically monoplanar secondary belt (10) for manufacturing a cellulosic fibrous structure is provided. The belt, having two mutually orthogonal principal directions, a machine direction and a cross machine direction, and having a reinforcing structure (30); and a framework of protuberances (20) joined to said reinforcing structure and extending outwardly therefrom to define deflection conduits (40) between the protuberances, the framework of protuberances having a semicontinuous pattern (25) and the deflection conduits having a semicontinuous pattern, is further provided. The protuberances and the deflection conduits have a vector component extending substantially throughout one principal direction of the belt, each protuberance of the pattern being spaced apart from an adjacent protuberance in the pattern. The protuberances have primary protuberances having a first width, T and nodes having a second width, N, wherein a ratio of N to T is from about 1.5 to about 5.</p> |
