Document Type and Number:
Japanese Patent JP2910969
Kind Code:
B2
Abstract:
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.
