Abstract
A fluid permeable fabric is disclosed having particular advantages as a dryer fabric for papermaking is disclosed. The fabric includes a number of helix A extending cross-wise in the fabric and joined together along the length dimension by pintles 38. Crevice spaces 40 formed by intermeshing bend portions extending into the loop openings C are closed by a contoured filler strip B. The contoured filler strip occupies the loop openings and includes contoured edges 56 which penetrate and occupy a substantial portion of the crevice spaces. A fabric having a low permeability is thus provided. An enlarged heat radiating surface 52 facing the paper side 39 of the fabric increases the heat transfer occurring in the paper web W to expedite drying. Crevice space 40 and tapered edges 56 of the filler element provide a guiding function which facilitates filler insertion in the loop openings.
