    • Air bubbles which are entrapped within the cells of an engraved applicator roller are displaced from the cells by wiping the surface of the engraved applicator roller with the bristles of a brush. An elongated brush mounted on a doctor blade head projects into a doctor blade reservoir. The bristles of the brush are disposed for wiping engagement against the engraved surface of an applicator roller which is wetted by liquid coating material. As the engraved applicator roller rotates in contact with the liquid material in the doctor blade reservoir, the bristles of the brush puncture the entrapped air bubbles and sweep the entrapped air away from the cells. The sweeping action of the bristles induces a relatively low pressure condition within the cells, which promotes the flow of liquid material into the cells. The elongated brush, which extends from one end of the doctor blade head to the other, serves as a baffle which blocks the transfer of dispersed air bubbles from the liquid material in the upper reservoir chamber above the brush to the lower reservoir chamber below the brush where the cells are being filled.
    • 通过用刷子的刷毛擦拭雕刻的涂布辊的表面,将被捕获在雕刻的涂布辊的单元内的气泡从电池移位。 安装在刮刀头上的细长的刷子突出到刮刀贮存器中。 刷子的刷毛设置成与被涂覆液体润湿的涂布辊的雕刻表面擦拭接合。 当雕刻的涂布辊与刮刀储存器中的液体材料旋转时,刷毛的刷毛刺穿被截留的气泡并将捕获的空气从细胞中扫除。 刷毛的扫掠作用在细胞内诱导相对较低的压力条件,这促进液体材料流入细胞中。 从刮刀头的一端延伸到另一端的细长刷用作阻挡分散气泡从刷子上方的上部储存室中的液体材料转移到刷子下方的下部储存室的挡板 那些细胞正在被填充。
