The present invention relates to a method for preparing an activated lignin composition. In addition, the present invention also relates to a method for further processing the thus activated lignin composition in a method for preparing a lignin-phenol formaldehyde resin. Such a lignin-phenol formaldehyde resin can be used in the manufacturing of laminates by replacing the traditional synthetic phenol formaldehyde resin.

A coating device for coating composite cellulose honeycomb support parts (1) each having a multiplicity of channels (5, 6) extending in an axial direction with an impregnation coating to increase fire, water-resistance and/or mechanical stability of the support parts (1). A conveyor (8) transports the support parts (1) in a conveying direction along a filling station (9) configured to pour impregnation agent (12) from above into the channels (5, 6), and damming agents (16) are configured such that the impregnation agent (12) is prevented or at least delayed from draining downwards out of the channels (5, 6) such that the impregnation agent (12) builds up in the channels (5, 6). An emptying station (19) is arranged downstream of the filling station (9) in the conveying direction, at which emptying station excess impregnation agent (12) drains out of the channels (5, 6) in the composite cellulose honeycomb support parts (1). A corresponding process is also disclosed.
