    Abstract: 1,074,208. Corrugating. TECHNIGAZ, and G. FOURNIER. June 30, 1964 [Jan. 13, 1964], No. 26961/64. Heading B3E. Apparatus for forming, in a metal sheet having a first series of substantially parallel corrugations, a second series of substantially parallel corrugations intersecting the first series comprises means to hold those portions of the sheet not to be altered in shape and punch and die means operable to fold the sheet to form said second corrugations without any stamping action. Metal sheet formed with one series of corrugations is held between upper plates P1, P2, having projections F to engage the formed corrugations, and lower plates P3, P4 having complementary projections I. The upper plates P1, P2 are linked by members hinged at (S1), (S2), (S3), Fig. 4 (not shown), and the lower plates P3, P4 by members hinged at (C1), (C2) (C3), (C4), (C5). In operation, the plates P1, P3 and P2, P4 are moved towards a centre line (MM 1 ) so that the edges (S2), (C2), (C5) effect a corrugation crossing the initial series of corrugations at right-angles. Alternatively, Fig. 6 (not shown), three V-shaped tools (S2), (C2), (C5) may be used. In a further embodiment, Fig. 7 (not shown), the descent of an upper plate causes, through cam means, the left and right-hand gripping members P1, P3 and P2, P4 to move towards one another and, through further cam means on the members P3, P4, lower projections to move towards one another.

FOURNIER。 1964年6月30日[1月 13，1964]，第26961/64号。 标题B3E。 用于在具有第一系列基本上平行的波纹的金属板中形成与第一系列相交的第二系列基本上平行的波纹的装置包括用于保持片材的这些部分不被改变的装置，并且冲模和冲模装置可操作以 折叠片材以形成所述第二波纹而没有任何冲压作用。 形成有一系列波纹的金属片被保持在上板P1，P2之间，具有突起F以接合形成的波纹，以及具有互补突起I的下板P3，P4。上板P1，P2通过铰接在 S1），（S2），（S3）， （C1），（C2）（C3），（C4），（C5）的构件铰接在一起的下板P3，P4（未示出）。 在操作中，板P1，P3和P2，P4朝向中心线（MM 1 ）移动，使得边缘（S2），（C2），（C5）影响穿过初始 系列波纹直角。 或者， 在图6（未示出）中，可以使用三个V形工具（S2），（C2），（C5）。 在另一实施例中， 如图7（未示出）所示，上板的下降通过凸轮装置使左右握持构件P1，P3和P2，P4彼此移动，并且通过构件P3，P4上的另外的凸轮装置 ，降低投影到彼此移动。
