Abstract
Un método para fabricar una hoja fibrosa que comprende: (a) formar una banda incipiente a partir de una solución acuosa de fibras para la fabricación de papel; (b) mover la banda incipiente sobre una superficie de transferencia; (c) poner una superficie grabada permeable de un cilindro grabado en contacto con la banda incipiente que tiene una consistencia desde aproximadamente 20% de sólidos hasta aproximadamente 70% de sólidos, en donde el cilindro grabado incluye un interior y un exterior, y la superficie grabada permeable (i) está formada sobre el exterior del cilindro grabado, (ii) tiene al menos una de una pluralidad de depresiones y una pluralidad de protuberancias, y (iii) es permeable al aire; (d) llevar la banda incipiente entre la superficie de transferencia y la superficie grabada permeable por sobre una longitud del arco de la superficie grabada permeable, donde la longitud del arco forma al menos una porción de una zona de moldeo; (e) aplicar vacío sobre al menos una porción de la longitud del arco, en donde el vacío se aplica en el interior del cilindro grabado para hacer que el aire fluya a través de la superficie grabada permeable al interior del cilindro grabado; (f) transferir la banda incipiente desde la superficie de transferencia hasta la superficie grabada permeable del cilindro grabado en la zona de moldeo, en donde el vacío se aplica durante la transferencia de la banda incipiente desde la superficie de transferencia hasta la superficie grabada permeable del cilindro grabado, de modo tal que las fibras para la fabricación de papel de la banda incipiente sean (i) redistribuidas sobre la superficie grabada permeable y (ii) modeladas por al menos una de la pluralidad de depresiones y la pluralidad de protuberancias de la superficie grabada permeable en la zona de moldeo para formar una banda de papel moldeada; (g) transferir la banda de papel moldeada a una superficie de captación; y (h) secar la banda de papel moldeada en una sección de secado para formar una hoja fibrosa. Métodos relacionados.A method of making a fibrous sheet comprising: (a) forming an incipient web from an aqueous solution of papermaking fibers; (b) moving the fledgling band onto a transfer surface; (c) placing a permeable etched surface of an etched cylinder in contact with the incipient band having a consistency of from about 20% solids to about 70% solids, wherein the etched cylinder includes an interior and an exterior, and the surface permeable etching (i) is formed on the exterior of the etched cylinder, (ii) has at least one of a plurality of depressions and a plurality of protrusions, and (iii) is permeable to air; (d) bringing the incipient web between the transfer surface and the pervious etched surface over an arc length of the pervious etched surface, where the arc length forms at least a portion of a molding zone; (e) applying vacuum over at least a portion of the length of the arc, wherein the vacuum is applied to the interior of the etched cylinder to cause air to flow through the permeable etched surface into the interior of the etched cylinder; (f) transferring the incipient band from the transfer surface to the pervious etched surface of the etched cylinder in the molding zone, wherein the vacuum is applied during the transfer of the incipient band from the transfer surface to the pervious etched surface of the etched cylinder, such that the papermaking fibers of the incipient web are (i) redistributed over the permeable etched surface and (ii) patterned by at least one of the plurality of depressions and the plurality of bumps on the surface pervious etching in the mold zone to form a molded paper web; (g) transferring the cast paper web to a pick-up surface; and (h) drying the shaped paper web in a drying section to form a fibrous sheet.
