摘要： An improved processes for making fluff pulp sheets mechanically eliminates many of the unwanted fiber-to-fiber bonding (fiber bundles) which may be contained in the sheet to produce consistent and uniform quality fluff pulp. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break a majority of fiber bundles contained in the web. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. A shoe press can be used to dewater the web after it is subjected to the pulsating shear forces. The web can be dried utilizing conventional drying equipment, such as cylindrical driers.

摘要翻译：用于制造绒毛纸浆片的工艺机械地消除了片材中许多不想要的纤维 - 纤维粘合（纤维束）。浆料浆料沉积在移动的底部成形网上以形成原料纤维网。纸浆与移动的顶部成形线接触。坯料经受上下脱水，产生分开形成的层，以减少纤维与纤维的粘结。当织物沿着底部成形线推进时，可以承受强烈的脉动剪切力以破坏纤维束。纸浆可以使用具有稀释控制的流浆箱沉积在底部成形网上，以选择性地调节纸浆的浓度。可以使用鞋压机在经受脉动剪切力后对其进行脱水。
