    摘要： La présente invention concerne une machine pour former, dans une tôle, des ondes parallèles et pour souder chacune de ces ondes à ses extrémités longitudinales.
    Cette machine est caractérisée en ce que la matrice de pliage 3 porte, à chacune de ses deux extrémités latérales et sur les faces internes en regard de ses deux plaques parallèles 4, 5, une paire d'organes de cambrage 8, 9 en saillie par rapport aux faces internes des deux plaques parallèles de la matrice, pour pincer entre eux, lors du mouvement relatif de la matrice 3 et du couteau 6, les deux lèvres extrêmes 2a, 2b des flancs de la tôle, et des moyens de soudage 11 portés par la matrice de pliage 3 et assurant le soudage des deux lèvres 2a, 2b de la tôle au voisinage immédiat de zone de pincement de celles-ci entre les organes de cambrage 8, 9.

    摘要： Method for bending a corrugated plate about an axis extending transversally to the valleys and crests respectively, by applying said plate between two press beams the opposite faces of which are provided with mutually corresponding and also with the crests and valleys of the plate corresponding alternating raised portions and recesses, and by then bringing the press beams together so as to press inwardly directed ribs into the bottoms of the valleys and pressing outwardly directed bulges into the adjacent sidewalls of said valleys, in such a way that in the first stage, in which the plate as seen in the longitudinal direction of the crests and valleys is supported through a length which is a multiple of the width of the ribs to be formed, the bulges are pressed only, while the ribs are formed in the subsequent stage.

    摘要： Equipment for manufacturing a separator for a fuel cell according to the present invention comprises: a press which receives a conveyed first metal strip and second metal strip that are unwound from a first uncoiler and a second uncoiler, respectively, vertically arranges the metal strips side by side, and forms patterns on each of the first metal strip and the second metal strip; a welding machine which is disposed adjacent to the press, overlaps the first metal strip and the second metal strip conveyed from the press, and integrally joins the metal strips by welding same in a state in which the patterns are aligned face-to-face with each other; and a plurality of guide rolls which are arranged in front of and behind the press and guide the first metal strip so that the first metal strip is supplied to the welding machine at an overlapping position with the second metal strip after passing through the press at a position spaced vertically apart from the second metal strip. The patterns may include: a first alignment hole, one among a cathode plate pattern and an anode plate pattern, and a trimming hole, which are formed in the first metal strip; and a second alignment hole, the other among the cathode plate pattern and the anode plate pattern, and a trimming hole, which are formed in the second metal strip.
