    • A web of tissue is formed in a twin wire former, followed by an air press for water removal in the pressing section, passing onto a Yankee dryer. A headbox injects stock between upper and lower dryer fabrics brought together on a breast roll. The fabrics moves over vacuum boxes, and the web is heated with steam and passed between an upper pressure box and a lower vacuum box forming an air press which dewaters the web. A sheet transfer pickup vacuum box holds the sheet to the upper fabric as the lower fabric diverges from the upper fabric. A pressure roller transfers the web onto a Yankee dryer. The fabrics are cleaned on vertical runs before returning to the breast roll. A final forming fabric is arranged to operated at a lower speed than the penultimate forming fabric so that a rush transfer and creping like action takes place.
    • 在双网成形器中形成纸幅,随后在压榨部中用空气压榨机除水,通过扬克烘缸。 流浆箱在上下干燥织物之间注入一起放在一起的乳房辊上。 织物在真空箱上移动,并且网被蒸汽加热并且通过上压箱和下真空箱之间,形成空气压榨机,该空气压榨机将纸幅脱水。 当下布料从上织物分叉时,片材传送拾取真空盒将片材保持在上织物上。 压辊将纸幅转移到扬克烘缸上。 在返回到乳房卷之前,将织物在垂直方向上进行清洁。 最终成形织物布置成以比倒数第二个成形织物低的速度运行,从而发生急剧转移和起皱作用。

    • A web of tissue is formed in a crescent former, followed by an air press for water removal in the pressing section, passing onto a Yankee dryer. A headbox injects stock between upper and lower dryer fabrics brought together on a breast roll. The fabrics move over vacuum boxes, and the web is heated with steam and passed between an upper pressure box and a lower vacuum box forming an air press which dewaters the web. A sheet transfer pickup vacuum box holds the sheet to the upper fabric as the lower fabric diverges from the upper fabric. A pressure roller transfers the web onto a Yankee dryer. The fabrics are cleaned on vertical runs before returning to the breast roll. A second upper fabric or transfer fabric operating at a lower speed then the first can be used to form a rush transfer between the forming fabrics and the Yankee dryer which increases web bulk and absorbency. Instead of a second fabric, a vacuum pressure roll may perform the rush transfer between the lower forming fabric and the Yankee dryer. The lower fabric may be divided into two fabrics, and the second fabric which passes through the air press, can be used to mold a texture into the web. The rush transfer and the molding fabric may be combined in one machine. A twin wire former may be used instead of a crescent former in each of the above configurations.
    • 在新月形成形体中形成纸幅,然后在压榨部分中用空气压榨机除水,通过扬克烘缸。 流浆箱在上下干燥织物之间注入一起放在一起的乳房辊上。 织物在真空箱上移动,并且网被蒸汽加热并且在上压箱和下真空箱之间通过,形成空气压榨机,该空气压榨机将纸幅脱水。 当下布料从上织物分叉时,片材传送拾取真空盒将片材保持在上织物上。 压辊将纸幅转移到扬克烘缸上。 在返回到乳房卷之前,将织物在垂直方向上进行清洁。 以较低速度操作的第二上织物或转移织物可以用于在成形织物和扬克烘缸之间形成一次冲击传递,这增加了纸幅的体积和吸收性。 代替第二种织物,真空压力辊可以在下成形织物和扬克烘缸之间执行冲击转移。 下部织物可以分成两种织物,并且通过空气压榨机的第二种织物可用于将织构模制成纤维网。 冲击传送和成型织物可以组合在一个机器中。 可以使用双线成形器代替上述构造中的每一个中的新月形物。
