A flame resistant to nonflammable composite panel (86) is produced from a nonextrudable core mixture (24) with a pourable, nonflammable filling material and a binder, and on both sides cover strips flexibly bonded to the core. For a continuous production of the composite panel (86) in one operation, the core mixture (24) is poured onto an inrunning lower cover strip (48), in contact with a lower adhesive film (16) .facing the core mixture (24), and a pile is formed there, extending over the entire width of the adhesive film, both [Lacuna] continuously and uniformly drawn through a V gap (40) and compacted there for the first time and calibrated to thickness, an upper adhesive film ( 30 ) , upwardly limiting the precompacted pore mixture (24'), is fed in and brought into contact with a continuously fad cover strip ( 46 ) and the sandwich is pressed with further compaction, heated, cooled and cut to the final length of the composite panel (86). The apparatus for carrying out the process preferably comprises a double-belt press (43) for the concluding pressing and heating, for maintaining the temperature and for cooling.
