An automatic machine (1) for providing corrugated sheet-like elements, which comprises means (3) for the continuous corrugation of a ribbon (5) which moves in a longitudinal direction, in which the corrugation means (3) comprise an upper conveyor (7) and a lower conveyor (9); the upper conveyor (7) comprises a plurality of upper abutment elements (70) which are extended substantially transversely with respect to the longitudinal direction of motion of the ribbon (5); the lower conveyor (9) comprises a plurality of lower abutment elements (90) which are extended substantially transversely with respect to the longitudinal direction of motion of the ribbon (5); the upper abutment elements (70) are interleaved with the lower abutment elements (90) in a work area (11); the upper abutment elements (70) each comprise a bar (71) adapted to make contact with the ribbon (5), while the lower abutment elements (90) each comprise a vane (91), which has a substantially wedge-like transverse cross-section and is adapted to receive the ribbon (5) in order to deform it. |
