SEAMED FELT FOR FORMING FIBER CEMENT ARTICLES AND RELATED METHODS

摘要

A fiber cement felt is includes a set of fine top machine direction yarns and a set of fine top cross machine direction yarns interwoven with the top machine direction yarns to form a top fabric layer. A set of coarse bottom machine direction yarns and a set of coarse bottom cross machine direction yarns are interwoven to form a bottom fabric layer. Seam loops merge with the bottom machine direction yarns and define longitudinal ends of the press felt. A batt layer overlies the top fabric layer. The fiber cement felt is positioned on a series of support rolls of a fiber cement forming machine, and then the longitudinal ends of the fiber cement felt is joined at the seam loops to form an endless belt. A fiber cement slurry is deposited on the fiber cement felt, and moisture is removed from the slurry.
