摘要： A micropore drying apparatus having a variable wet flow resistance. The flow resistance preferably decreases in the machine direction. The micropore drying apparatus may comprise a single integral unit having an decreasing wet flow resistance from the beginning to the end of the unit. Alternatively, the micropore drying apparatus may comprise a plurality of discrete units, each unit having a successively lesser flow resistance than that of the preceding unit. Alternatively, a hybrid arrangement may be used wherein each discrete unit has a successively decreasing flow resistance within that unit. The micropore drying apparatus may comprise one or more micropore drying media. The micropore drying media have pores which allow air flow therethrough. The pores are disposed in a grid, to form a field of pores. The decreasing flow resistance may preferably be provided by adjusting one or more of said pores, which affect the flow resistance through a single pore or through the entire field of the pores.

摘要： An apparatus for drying a cellulosic fibrous structure. The apparatus comprises a micropore medium having pores therethrough. The pores are the limiting orifice in the air flow used in the drying process. The micropore medium has a relatively low wet pressure drop therethrough. This relatively low wet pressure drop advantageously reduces the energy costs used in drying, and/or allows for greater drying to be obtained at constant energy costs.

摘要： A micropore drying apparatus having a noncircular profile. The apparatus has a machine direction and dries a web thereon as the web or apparatus moves in the machine direction. The micropore drying apparatus comprises a micropore drying medium which has pores therethrough smaller than the interstitials in the web to be dried thereon. The micropore drying medium may be movable or stationary, as desired. The noncircular profile may have a major axis which is substantially vertically oriented. This arrangement provides the advantage that greater residence time for the web to be dried thereupon is provided, without increasing the machine direction footprint.

摘要： A differential density single lamina web of cellulosic fibers comprises at least two pluralities of micro-regions disposed in a non-random and repeating pattern: a first plurality of high density regions and a second plurality of low density regions. The high density regions comprise cellulosic fibers comprising fluid latent indigenous polymers (FLIP), such as hemicelluloses and lignin. The fibers of the high-density regions are FLIP-bonded, i.e., bonded together by a process of softening, flowing and immobilization of the FLIP between the cellulosic fibers of the high density regions. The process for making the web comprises the steps of providing a plurality of papermaking fibers comprising FLIP; providing a macroscopically monoplanar papermaking belt having a web-facing surface and deflection conduits; depositing the plurality of the cellulosic fibers on the papermaking belt to form a web; heating the web to a temperature sufficient to cause the FLIP contained in a first portion associated with the web-facing surface of the belt to soften; impressing the web-side surface of the belt into the web; immobilizing the flowable FLIP and creating FLIP-bonds between the fibers comprising the first portion of the web.

摘要： A process and an apparatus for making a foreshortened paper web are disclosed. A wet web disposed on a fluid-permeable papermaking fabric is being pressed between two parallel and mutually opposed first and second press surfaces, the first press surface contacting the web, and the second press surface contacting the fabric. In the continuous process, the press surfaces, the web and the fabric move in a machine direction. Under pressure, at least selected portions of the web become densified and adhered to the first press surface which can be treated with a creping adhesive. The first surface is heated to create a temperature differential between two surfaces. The temperature differential causes the water contained in the web to move from the web into the fabric, thereby drying the web. After the web is released from the pressure, the web is foreshortened either by creping or by transferring the web to a slower moving transfer fabric. Creping is performed with a creping doctor blade juxtaposed with the creping surface having the web adhered thereto. A creping adhesive may be deposited on the creping surface according to a predetermined pattern. The creping surface may comprise the first press surface. Optionally, the web may be calendered after being foreshortened.
摘要翻译： 公开了一种制造缩短纸幅的方法和装置。 布置在流体渗透性造纸织物上的湿网被压在两个平行和相互对置的第一和第二挤压表面之间，第一压榨表面接触幅材，第二压榨表面与织物接触。 在连续过程中，压力表面，纤维网和织物在机器方向移动。 在压力下，幅材的至少选定部分变得致密化并粘附到可用起皱粘合剂处理的第一压制表面。 第一表面被加热以在两个表面之间产生温差。 温度差使得包含在幅材中的水从纸幅移动到织物中，从而干燥纸幅。 在幅材从压力释放之后，纤维网通过起皱或通过将幅材转移到较慢移动的转印织物而被缩短。 用起皱刮刀与起皱表面并排的起皱是将纤维网粘附在其上。 起皱粘合剂可以根据预定图案沉积在起皱表面上。 起皱表面可以包括第一压制表面。 可选地，网可以在被缩短之后被压延。
