    • Apparatus for removing an excess amount of a liquid coating material from portions of a moving web (12) following coating of the moving web (12) with the liquid coating material along a coating path. A vacuum head (34) having a suction slot (52) is defined by upstream and downstream walls and adapted to be movably positioned in an inoperative position away from the coating path and in an operative position contacting at least a portion of the liquid coating material on the moving web (12) along the coating path, the downstream wall positively displacing a portion of the liquid coating material when the vacuum head (34) is positioned in the operative position. A suction means is operatively coupled to the vacuum head (34) for establishing a vacuum manifold within the suction slot (52) and communicating with a disposal system. A liquid supply means is operatively coupled to the vacuum head (34) for supplying liquid to the suction slot (52).
    • 装置,用于从移动的纤维网(12)按照与移动幅材(12)与沿涂布路径的液体涂层材料的涂层的部分的液体涂层材料的过量去除。的真空头(34),其具有一个吸槽( 52)通过上游和下游壁和angepasst定义为在至非工作位置可移动地定位在距涂料路径远离并且在操作位置沿着涂布轨迹的移动幅材(12)上至少接触液体涂层材料的一部分 ,下游壁正位移液体涂层材料的一部分当真空头(34)在操作位置被定位。 吸引机构可操作地联接到所述真空头(34),用于建立吸槽(52)内的真空歧管和与处理系统进行通信。一种液体供给装置被可操作地耦合到所述真空头(34),用于将液体供应至 所述吸槽(52)。
