Abstract

A folding unit for final folding of the outer panels (55, 56) of a corrugated board sheet (18) in in-line manufacturing of corrugated board boxes, comprising a pair of parallel and laterally displaceable folding beams (1, 2) with a respective endless conveyor belt (3, 4), which extend from the inlet (19) of the folding unit to a pair of press rolls (9, 10) at the outlet (20) of the folding unit. A pair of folding rules (5, 6) are arranged under the respective folding beams (1, 2) and extend from the inlet (19) of the folding unit and towards, but not all the way to, the outlet (20) of the folding unit. A pair of folding bars (33, 34) which are fixedly positioned outside the respective folding rules (5, 6) and at an angle to the respective folding rules are arranged in the front portion of the folding unit, as seen in the transport direction (15) of the corrugated board sheets (18). A pair of folding belts (7, 8) are arranged under a respective folding rule (5, 6) to cooperate therewith and extend from an associated deflecting roller (16) with a vertical axis at the terminal end of the folding bars (33, 34) in the transport direction (15), to an associated deflecting roller (17) with a horizontal axis substantially adjacent the pair of press rolls (9,10). A lifting device (38, 39, 43) is positioned in front of the pair of deflecting rollers (17) and is brought into contact with the folded panels (55, 56) when the front edge (61) of the corrugated board sheet (18) has passed the lifting device (38, 39, 43) and successively lifts them, so that when said front edge (61) is introduced in the nip between the press rolls (9, 10) at least the portion of the panels (55, 56) that is situated between the press rolls (9, 10) and the lifting device (38, 39, 43) has been folded 180°.
