ABSTRACT:
There is proposed a process of continuously producing a catalyst plate, wherein a thin metal plate is formed by use of a blade with slits in the widthwise directions thereof, expanded in the longitudinal direction thereof into an expanded metal plate having formed therein meshes, the expanded metal plate thus formed is corrected in shape, degreased, thereafter, molten metal such as molen aluminum is sprayed onto the expanded metal plate to form roughened surfaces on the opposite sides of the expanded metal plate, further, a catalytic substance is deposited onto the roughened surfaces, thereafter, formed into a predetermined form, and shorn into pieces. There is proposed a pinch roll system having a tension roll, in which end portions in the widthwise direction are vertically movable so as to be used as a corrector for the expanded metal plate, and a stepping press system to be used as a former for the expanded metal plate.
