APPARATUS FOR PREPARING CORRUGATED BOARD-SHAPED CATALYST

PURPOSE:To efficiently mold a plate catalyst into a corrugated shape while preventing the release of a catalyst, by mounting a roll means wherein rolls each having a spiral corrugated uneven surface are meshed in two upper and lower stages, a rotary drive apparatus, a plate catalyst supply means and a protective sheet supply means. CONSTITUTION:As molding rolls, upper and lower rolls 21, 22 each having a spiral corrugated uneven surface are arranged in a meshed state and rotated to supply a plate catalyst 23 in a direction capable of sighting the metal lath perforations symmetrically staggered manner). At this time, polymer sheets 25 are supplied and the plate catalyst 23 is supplied between the rolls 21, 22 in the state held between the polymers sheet 25. Subsequently, molding pressure is applied to both ends of the upper roll 21 to continuously mold a corrugated board-shaped catalyst 24 and the polymer sheet 25 are recovered while separately wound up and down. By this method, since the corrugated board-shaped catalyst having a predetermined angle in the molding direction can be obtained, the folded part of corrugation can be molded at the part of the notched width of the metal lath.
