Abstract
A secondary belt for papermaking. The belt has a framework of protuberances arranged in a semicontinuous pattern to provide a semicontinuous pattern of deflection conduits. The semicontinuous pattern is distinguished from the discrete and continuous patterns of the prior art. The protuberances may be generally parallel, or may provide individual cells within the deflection conduits between the protuberances. Also disclosed is the paper made on such a secondary belt.
Claims7
A macroscopically monoplanar secondary belt for manufacturing a cellulosic fibrous structure, and having two mutually orthogonal principal directions, a machine direction and a cross machine direction, said belt comprising:
- a reinforcing structure;
- and
- a framework of protuberances joined to said reinforcing structure and extending outwardly therefrom to define deflection conduits between said protuberances, said framework of protuberances comprising a semicontinuous pattern, said protuberances having a vector component extending substantially throughout one principal direction of said belt, each said protuberance of said pattern being spaced apart from an adjacent protuberance in said pattern.
