Title: Manufacture of partition plate used for heat exchanging element
Inventor: KASAI KATSUYA
IPC: F28F3/04
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To see that the paper material does not tear by engaging a plurality of push pieces in order with recesses thereby forming uneven stripes in order in paper material given to a press device, in the case of forming uneven stripes in the paper material. SOLUTION: The paper material 9 of a cut-out plate stripe is caught with a male mold 12 and a female mold 13, and a recessed stripe 14 provided at the push face 17 of the female mold 13 engages with a push piece 8 provided at the push face 17 of the male mold 12, whereby an uneven stripe is made in the paper material 9. Since the push piece 8 is supported by the elastic body 21 inside a storage groove 15, the quantity of protrusion from the push face 16 of the male mold 12 is largest at the center of the male mold 12, and it decreases as it goes toward both ends. Hereby, in the case of performing press molding of integrated type, a time lag can be given to the time when the push piece 8 begins to push the paper material 9. Accordingly, the tensile stress falling at a time on the paper material 9 decreases, so it becomes hard to tear.
