Abstract

The invention relates to a moistening system (1) for presses (100) for compressing material cakes (200) mixed with binding agents, preferably continuously operating presses (100), in particular for producing composite panels, preferably engineered wood boards, comprising a first moistening agent application device. The first moistening agent application device (3) comprises a first application roll (7), which can be set from above against the material cake (200) conveyed by a conveyor unit (300) of the press, at least one first dosing roll (9), which can be set against the first application roll (7), and a first moistening agent bath (11). The at least one first dosing roll (9) is immersed in the first moistening agent bath (11) for taking up moistening agent and comprises at least one wiper roll (13), which can be set against each first dosing roll (9) and by means of which the amount of moistening agent taken up by each first dosing roll (9) can be adjusted.
