Abstract (en)

[origin: EP2484516A1] The device comprises: a feed path for corrugated cardboard (N1, N2, N3); along said feed path, a series of sequentially arranged heated plates (103) defining a sliding surface for said corrugated cardboard, said series of heated plates being subdivided into a plurality of groups (109A, 109B, 109C, 109D) of heated plates (103); pressing members (105) to press said corrugated board (N1, N2, N3) against said sliding surface. To heat the plates (103) steam is supplied through a pressurized steam supply line (111). For each group (109A, 109B, 109C, 109D) of heated plates (103), a pressure regulating valve (113A, 113B) is provided between the steam supply line (111) and the heated plates of the respective group of heated plates, to supply said heated plates with steam under regulated pressure. Furthermore, for each group of heated plates (103), a condensate relief valve (134A, 134B, 134C, 134D) allows to discharge the condensate from the various groups towards a common condensate collecting line (130) and from here to a condensate storage tank (136).
