    • A system and process for producing tissue webs is disclosed. The tissue webs (16) are formed from an aqueous suspension of fibers and dried using a through-air dryer (28). During formation of the web, the web is transferred from a transfer fabric (20) to a throughdrying fabric (24) and then conveyed around a drying cylinder (26) of a through-air dryer. In accordance with the present invention, a pressurized roll (50) emits a gaseous stream through a pressurized zone (52) that pushes and transfers a wet web from a transfer fabric to the throughdrying fabric. The amount of pressure used during the transfer can vary depending upon the particular application and may be used to control the bulk of the web. By using a pressurized transfer roll, the amount the throughdrying fabric is wrapped around the drying cylinder of the through-air dryer can be maximized for increasing the efficiency of the system and the process.
    • 公开了一种用于生产组织网的系统和方法。 纸幅(16)由纤维的水性悬浮液形成,并使用通风干燥器(28)进行干燥。 在幅材的形成期间,幅材从转印织物(20)转移到穿透干燥织物(24),然后在通风干燥器的干燥筒(26)周围传送。 根据本发明,加压辊(50)通过加压区域(52)排出气流,该加压区域将湿织物从转移织物推送并转移到穿透干燥织物。 转移期间使用的压力量可以根据具体应用而变化,并且可以用于控制幅材的大部分。 通过使用加压转移辊,穿透干燥织物缠绕在通风干燥器的干燥筒上的量可以最大化以提高系统和过程的效率。
