Abstract
An endless dryer fabric having a paper fiber support surface and a machine contact surface arranged about drying drums within a drying machine. The support surface is adopted to allow air to pass there through while carrying paper forming fibers through the drying machine during drying. The fabric consists of a plurality of elliptically shaped coil monofilaments arranged side by side in intermeshing relationship with elongated pintles extending through the intermeshed portions of the coils forming the fabric continuous. An elongated stuffer filament having a cross-section selected from a rhomboid parallelogram, a rhombus parallelogram and a pointed ellipse is positioned to extend diagonally through central portions of each of said coils leaving diagonally opposed equal sized open areas within each coil. The stuffer filaments have opposed shaped edges which engage across the entire width of adjacent coil forming filaments forming secure closures against air passages along upper and lower opposed ends of the central portions. The stuffer filaments are positioned within each coil with its machine direction edge engaging below a connecting pintle and its trailing edge engaging above a connecting pintle.
