PCT No. PCT/FR91/00245 Sec. 371 Date Oct. 2, 1992 Sec. 102(e) Date Oct. 2, 1992 PCT Filed Mar. 28, 1991 PCT Pub. No. WO91/15343 PCT Pub. Date Oct. 17, 1991.The invention concerns a punch block support arm adaptable to a perforating device as well as a process for mounting punches on such a block. According to the invention, the block comprises a narrow slot (12, 20, 23) across the whole block thickness, and extending on the whole length of the punch array. The slot extends, at each of its ends (23), perpendicular to the alignment axis (26) of the punches (20, 22), in order to define a longitudinal bar (14) and two transversal bars (15, 16), the slot being located so that the distortion of the longitudinal bar brings relatively closer the portions of transversal bars so as to immobilize the punches.
