    Abstract: A pressurized box is positioned opposite a vacuum box. The pressurized box has a leading cross machine direction baffle with a ceramic shoe which engages a forming fabric, and a trailing cross machine direction baffle of similar construction. Two end deckles complete the pressurized box. The leading cross machine direction baffle presses against a resilient seal which causes a web contained between upper and lower forming fabrics to wrap about the baffle shoe a few degrees forming an effective end seal which does not allow air to bypass the baffle. The trailing cross machine direction baffle is positioned over a vacuum box which prevents air from leaking around the trailing baffle. A vacuum box draws air through the forming fabrics and the web, from the pressurized box increasing the total pressure gradient across the web to 20 to 30 psi or more. The pressure box and opposed vacuum box form an air press. The pressure box is positioned and held against the forming fabrics by opposing air tubes. An alternative embodiment utilizes a suction roll positioned beneath the pressure box and having a suction gland positioned beneath the portion of the roll which backs the pressure box.

    Abstract translation: 加压箱位于真空箱对面。 加压箱具有导向的横向机械方向挡板，其具有接合成形织物的陶瓷靴和类似结构的后横向机械方向挡板。 两端盖完成加压箱。 领先的横向机械方向挡板压靠弹性密封件，其使得包含在上部成形织物和下部成形织物之间的纤维网围绕挡板缠绕几度，形成不允许空气绕过挡板的有效端部密封。 后方的横机方向挡板位于真空箱上方，防止空气在后挡板周围泄漏。 真空箱通过成形织物和纤维网从加压箱中吸入空气，将整个幅材上的总压力梯度提高到20至30psi或更大。 压力箱和相对的真空箱形成空气压机。 压力箱通过相对的空气管定位并保持抵靠成形织物。 替代实施例使用位于压力箱下方的抽吸辊，并且具有位于辊的部分之下的吸入压盖，所述抽吸压盖支承压力箱。

    CPC classification number: D21F11/006

    Abstract: The internal bulk of a tissue web can be improved during manufacturing of the basesheet by subjecting the tissue web to differential pressure while supported on a coarse fabric at a consistency of about 30 percent or greater. The differential pressure, such as by applying vacuum suction to the underside of the coarse fabric, causes the wet web to deflect into the openings or depressions in the fabric and "pop" back, resulting in a substantial gain in thickness or internal bulk. The method is especially adapted to improve the internal bulk of wet-pressed tissue webs.

    Abstract translation: 组织纤维网的内部本体可以在制造基片期间通过使组织织物受到差压而同时以约30％或更大的稠度支撑在粗糙织物上而得到改善。 差压，例如通过对粗织物的下侧施加真空吸力，导致湿纸幅偏转到织物中的开口或凹陷中并“弹回”，导致厚度或内部体积的显着增加。 该方法特别适用于改善湿压纸幅的内部体积。
