APPARATUS, SYSTEM, AND PROCESS FOR DETERMINING CHARACTERISTICS OF A SURFACE OF A PAPERMAKING FABRIC

摘要

A process of determining the depth of a pocket in a woven fabric. A representation is formed of a portion of a surface of the woven fabric to provide a fabric representation showing at least one of (i) at least one of locations and sizes of knuckles that are a part of the surface of the fabric and (ii) at least one of locations and sizes of pockets that are formed in areas between the knuckles. Particular knuckles are identified that surround a particular pocket. A path is determined in the fabric representation that passes from a first of the knuckles across the particular pocket to a second of the knuckles. The fabric is scanned using a measurement device along a line that corresponds to the determined path. A depth of the particular pocket is determined, to which cellulosic fibers can penetrate in a papermaking process, based on the scan.

1. A process of determining the depth of a pocket in a woven fabric that includes warp yarns and weft yarns, the process comprising:
forming a representation of a portion of a surface of the woven fabric to provide a fabric representation, the fabric representation showing at least one of (i) at least one of locations and sizes of knuckles that are a part of the surface of the fabric and (ii) at least one of locations and sizes of pockets that are formed in areas between the knuckles; identifying particular knuckles of the knuckles in the fabric representation that surround a particular pocket of the pockets in the fabric representation; determining a path in the fabric representation that passes from a first of the identified particular knuckles across the particular pocket to a second of the identified particular knuckles; scanning the woven fabric using a measurement device along a line that corresponds to the determined path to provide a scan of the woven fabric; and determining a depth of the particular pocket, to which cellulosic fibers can penetrate in a papermaking process, based on the scan along the line that corresponds to the determined path.
