摘要 PCT No. PCT/FR95/00586 Sec. 371 Date Jan. 5, 1996 Sec. 102(e) Date Jan. 5, 1996 PCT Filed May 5, 1995 PCT Pub. No. WO95/30537 PCT Pub. Date Nov. 16, 1995Machine (1) and method of manufacture of a single-face corrugated board sheet whereby a fluted cardboard sheet (23) is glued to a flat sheet. The machine comprises three heating cylinders having parallel axes, tangently arranged pairwise and means (26) for positive traction driving the corrugated board sheet, said means being located downstream of the path of the corrugated board in relation to the three cylinders. The fluted sheet is pressed onto the cylinder downstream of the first contact (29) between the flat sheet and the fluted sheet, in an arc of a circle corresponding to an angle at the center (alpha) of a first predetermined value greater then zero. Said positive driving means are associated with complementary means for heating said corrugated board.
