ABSTRACT:
An apparatus for depositing a fibrous diaphragm on electrodes having foraminous surfaces which includes a tank having a bottom and side walls. A dividing means, such as a rack, having a plurality of frames, each having a top edge, and side edges, is positioned in the tank. The rack may be attached along one of the side edges of the frames to one of the side walls of the tank or it may be secured to support members positioned on the bottom of the tank. The frames of the rack are spaced apart from each other by a distance related to the spacing between electrodes. The frames may have cross members joining the side edges and have rollers on the top edge and the cross members.
The apparatus is suitably used in depositing a fibrous diaphragm on electrodes having a large surface area and narrow spacing between adjacent electrodes. The apparatus prevents bridging of the fiber between electrodes and also prevents adjacent electrodes from being drawn together during the application of a vacuum to deposit the diaphragm.
