Abstract
A method of producing a panel includes:
- placing an assembly including core elements and impregnatable material webs extending along and between the core elements on a mold, which assembly includes a first side and a second side which is situated opposite the first side,enclosing the assembly under a cover layer in a sealing manner with respect to the mold,introducing at least one inlet for injection material, which inlet ends at a first side of the assembly,connecting the space which is enclosed by the cover layer and the mold to a discharge,injecting injection material via the inlet on the first side of the assembly and causing the injection material to move along via paths formed by the material webs between the core elements,discharging air and/or gas from the enclosed space via the discharge via underpressure at a position which is at a different level to the position where the inlet ends.
