摘要： A cover device (10) is disclosed for use in a dewatering shoe or other drainage device of a papermaking machine. The cover device (10) includes a plate (12) of expanded metal which defines a plurality of elongate holes (14, 15, 16, 17, 18, 19, 20 and 21) for the passage therethrough of water as indicated by the arrow (22) removed from a web W disposed on a dewatering screen (24) moving in a machine direction MD relative to the cover device (10). The arrangement is such that the dewatering screen (24) is disposed between the web W and the cover device (10) so that the water (22) is removed from the web W through the dewatering screen (24) and then through the elongate holes (14 to 21).
