Abstract:
An endless dryer fabric having a paper fiber support surface and a machine contact surface arranged about drying drums within a drying machine, said support surface being adopted to allow air to pass there through while carrying paper forming fibers through said drying machine during drying, said fabric comprising;a plurality of elliptically shaped coil monofilaments arranged side by side in intermeshing relationship and elongated pintles extending through intermeshed portions of said coils forming said fabric continuous;elongated stuffer filaments, having a cross-section selected from one of a rhomboid parallelogram, a rhombus parallelogram, and a pointed ellipse, extending diagonally through central portions of each of said coils leaving diagonally opposed equal sized open areas within each coil, said stuffer filaments having opposed shaped edges which engage across the entire width of adjacent coil forming filaments forming elongated secure closures against air passage along upper and lower opposed ends of said central portions; whereby,air passage through said dryer fabric is equalized throughout its passage through said drying machine allowing even drying and preventing flutter of said paper forming fibers.
