    • PROBLEM TO BE SOLVED: To provide a forming roll capable of easily forming a metallic sheet for a catalyst support in the manner that the corrugated metallic sheets are free of engaging adhesion to each other when superimposed. SOLUTION: A plurality of blades 11 of the same specification are such that roll peak parts 10a, 10e corresponding to the corrugated peak part and the louvered peak part, which are to be shaped on the circumferential surface of a metallic sheet, are formed at prescribed allocated equal angles θ around the center point 0 of the blade, as are roll valley parts 10b, 10d corresponding to the corrugated valley part and the louvered valley part; these blades 11 are laminated with a pitch shifted using the allocated angle θas one pitch, and the roll is constituted by interposing a spacer between the blades 11 having a different phase angle, thereby providing plural louvered valleys in the corrugated peak part in the direction of the fold of the corrugation as well as providing plural louvered peaks in the corrugated valley part in the same direction, and facilitating the forming of the metallic sheets which are free of engaging adhesion to each other when superimposed.

    • PURPOSE:To prevent the cracking at the time of drawing by forming crease in longitudinal/latitudinal two directions on the engine cover sheet, in which asbesto is stuck on Al sheet. CONSTITUTION:The latitudinal drawing means A is formed so that the rotating shafts 5a1-5an from a first to n-th are placed in the same plane apart a specific space with facing a pair of rotating shaft groups (a), (b), further for the rotating shaft group (a), an abacus bead shape pressing roller 6a is approached in sequence and is stuck on each left/right symmetrically to each rotating shaft from 5a1-5an. For other rotating group (b), the same abacus bead shape roller 6b is stuck to position on both sides of each pressing roller 6a of each rotating shaft, also the longitudinal drawing means B is formed so that long sideway spurgears 8a, 8b are stuck on a pair of rotating shafts 7a, 7b and the teeth 9 of each spurgear are reversed each other with holding the prescribed distance so as to mesh between facing teeth each other.
