DEVICE FOR MANUFACTURING METAL BASE MATERIAL FOR EXHAUST GAS PURIFICATION

WIPO Patent Application WO/2024/048372

A1

This device for manufacturing a metal base material for exhaust gas purification, which is formed by winding a planar plate and a corrugated plate provided on the planar plate, comprises first and second wind-up shafts, a rotation mechanism, and a movement mechanism. The first wind-up shaft is cantilevered, and has, on the free end side thereof, a first pair of facing pieces defining a first slit and facing each other. The second wind-up shaft is cantilevered, and has, on the free end side thereof, a second pair of facing pieces defining a second slit and facing each other. The rotation mechanism coaxially arranges the rotation axes of the first wind-up shaft and the second wind-up shaft, causes the free ends of the first wind-up shaft and the second wind-up shaft to face each other, arranges at least the planar plate and/or the corrugated plate so as to be insertable into the first slit and the second slit, and rotates the first wind-up shaft and the second wind-up shaft in the same direction in synchronization with each other. The movement mechanism causes the free ends of the first wind-up shaft and the second wind-up shaft to move closer to or away from each other while coaxially arranging the rotation axes of the first wind-up shaft and the second wind-up shaft.
